We’ll cover everything from simple battery disconnects to advanced scanner techniques, plus troubleshooting tips and best practices to keep your Commodore running smoothly.

Why the Check Engine Light Comes On

Before you reset the light, it’s crucial to understand what triggered it. The VE SS, like all modern vehicles, is equipped with an onboard diagnostics system (OBD2) that constantly monitors engine performance, emissions, and various sensors. When something falls outside normal parameters, the system logs a trouble code and illuminates the check engine light.

Common causes include:

  • A loose or missing gas cap (one of the most frequent—and easiest—to fix)
  • Faulty oxygen (O2) sensors
  • Mass airflow (MAF) sensor issues
  • Spark plug or ignition coil problems
  • Catalytic converter inefficiency
  • Evaporative emissions system leaks
  • Exhaust gas recirculation (EGR) valve malfunctions

Ignoring the light can lead to reduced fuel economy, increased emissions, poor performance, or even engine damage over time. So while resetting the light is helpful, it’s only part of the solution. Always diagnose the root cause first.

Method 1: Using an OBD2 Scanner (Recommended)

The most reliable and safest way to reset the check engine light on your VE SS is with an OBD2 scanner. This tool connects to your car’s diagnostic port and communicates directly with the engine control unit (ECU). It reads trouble codes, explains what they mean, and allows you to clear them—without risking damage to your vehicle’s electronics.

What You’ll Need

  • An OBD2 scanner (basic models start around $20; Bluetooth models that work with smartphone apps are also great)
  • Your VE SS parked on a level surface with the engine off
  • Ignition key

Step-by-Step Instructions

Step 1: Locate the OBD2 Port

The OBD2 port in a Holden VE SS is typically located under the dashboard on the driver’s side, near the steering column. It’s a 16-pin connector, usually black or gray, and may be tucked behind a small panel or cover. If you can’t find it, check just below the steering wheel or near the fuse box.

Step 2: Plug in the Scanner

Insert the OBD2 scanner’s connector into the port. Make sure it’s fully seated. Some scanners have a locking mechanism—don’t force it, but ensure it’s secure.

Step 3: Turn the Ignition On (But Don’t Start the Engine)

Turn the key to the “ON” position (dashboard lights should illuminate), but leave the engine off. This powers up the ECU and allows the scanner to communicate with it.

Step 4: Power On the Scanner

Turn on your OBD2 scanner. Most devices will automatically detect the vehicle and begin scanning. If prompted, select your vehicle make (Holden), model (VE SS), and engine type (usually 6.0L V8).

Step 5: Read the Trouble Codes

Navigate to the “Read Codes” or “Scan” function. The scanner will retrieve any stored diagnostic trouble codes (DTCs), such as P0420 (catalytic converter efficiency) or P0171 (system too lean). Write these down—they’re essential for diagnosing the issue.

Step 6: Clear the Codes

Once you’ve addressed the problem (e.g., tightened the gas cap, replaced a sensor), go to the “Clear Codes” or “Erase DTCs” option. Confirm the action when prompted. The scanner will send a command to the ECU to reset the check engine light.

Step 7: Verify the Reset

After clearing, turn the ignition off and back on. The check engine light should remain off. If it comes back on immediately, the issue may not be fully resolved, or a new code has been triggered.

Tips for Using an OBD2 Scanner

  • Use a scanner with live data capability to monitor sensor readings in real time.
  • Some advanced scanners can perform system tests (e.g., EVAP leak test) to confirm repairs.
  • Bluetooth scanners like the BlueDriver or FIXD work with iOS/Android apps and provide detailed explanations of codes.
  • Always clear codes after repairs—don’t just read them and hope the light goes away.

Method 2: Disconnecting the Battery (Manual Reset)

If you don’t have an OBD2 scanner, you can reset the check engine light on your VE SS by disconnecting the battery. This method forces the ECU to reset by cutting power, which clears temporary memory—including trouble codes and the check engine light.

However, this approach has drawbacks: it may reset your radio presets, clock, seat memory, and adaptive learning (like throttle response and transmission shift points). It also doesn’t guarantee the light won’t return if the underlying issue persists.

What You’ll Need

  • Wrench or socket set (usually 10mm for battery terminals)
  • Safety gloves and glasses (optional but recommended)
  • Your VE SS parked and engine off

Step-by-Step Instructions

Step 1: Turn Off the Engine and Remove the Key

Ensure the vehicle is completely off. Remove the key from the ignition to prevent any electrical surges.

Step 2: Locate the Battery

In the VE SS, the battery is under the hood on the driver’s side. It’s a standard 12V lead-acid battery, usually secured with a hold-down clamp.

Step 3: Disconnect the Negative Terminal First

Using your wrench, loosen the nut on the negative (black) battery terminal. Always disconnect the negative cable first to avoid short circuits. Pull the cable off and tuck it away from the battery so it doesn’t accidentally touch the terminal.

Step 4: Wait 15–30 Minutes

This waiting period allows the ECU’s capacitors to discharge fully, ensuring a complete reset. Some sources recommend up to 30 minutes for older vehicles, but 15 minutes is usually sufficient for the VE SS.

Step 5: Reconnect the Battery

Reattach the negative terminal and tighten the nut securely. Then reconnect the positive (red) terminal. Make sure both connections are tight and corrosion-free.

Step 6: Turn the Ignition On

Turn the key to the “ON” position. The check engine light should briefly illuminate (as it does during startup) and then turn off. If it stays off after starting the engine, the reset was successful.

Important Notes

  • This method may not clear all codes—especially hard or pending codes.
  • Some VE SS models with advanced electronics may require a relearn procedure for the throttle body or transmission.
  • If the light returns within a few days, the problem wasn’t fixed—don’t keep disconnecting the battery.

Method 3: Ignition Cycle Method (Drive Cycle Reset)

Some VE SS owners report success using the “ignition cycle” method—a series of on/off cycles that can reset the ECU under certain conditions. This method works best for minor glitches or after a temporary sensor fault.

Step-by-Step Instructions

Step 1: Turn the Ignition On (Engine Off)

Turn the key to the “ON” position. Wait 3 seconds.

Step 2: Turn the Ignition Off

Turn the key back to “OFF.” Wait 3 seconds.

Step 3: Repeat 3–5 Times

Repeat this cycle 3 to 5 times in a row. This simulates a power cycle and may reset the ECU’s temporary memory.

Step 4: Start the Engine

After the final cycle, start the engine. If the check engine light was due to a minor fault, it may now be off.

When This Method Works

  • After a loose gas cap was tightened
  • Following a brief sensor dropout (e.g., during heavy rain or rough roads)
  • When no hard codes are stored

Limitations

  • Does not work for persistent or severe issues
  • Not a substitute for proper diagnosis
  • May not clear all monitors required for emissions testing

Completing the Drive Cycle

After resetting the check engine light—whether via scanner or battery disconnect—your VE SS needs to complete a “drive cycle.” This is a series of driving conditions that allow the ECU to re-test all monitored systems and confirm they’re working properly.

Without completing the drive cycle, the vehicle may still fail an emissions test, even if the light is off.

Typical VE SS Drive Cycle

  1. Cold Start: Start the engine when it’s cold (hasn’t run for at least 8 hours).
  2. Idle for 2–3 Minutes: Let the engine idle to reach operating temperature.
  3. City Driving: Drive at speeds between 25–45 km/h for 5–10 minutes, including stops and starts.
  4. Highway Driving: Accelerate to 80–100 km/h, maintain speed for 10–15 minutes.
  5. Decelerate: Slow down gradually without braking hard.
  6. Repeat if Necessary: Some monitors (like EVAP or catalytic converter) may require multiple cycles.

Tips for Success

  • Avoid short trips—longer drives help complete monitors faster.
  • Use cruise control on the highway to maintain steady speed.
  • Don’t disconnect the battery during the drive cycle—it will reset progress.
  • Use an OBD2 scanner to check monitor status (look for “Ready” or “Complete”).

Troubleshooting Common Issues

Even after resetting, the check engine light may return. Here’s how to troubleshoot:

Light Comes Back On Immediately

  • The issue wasn’t fixed—recheck your repairs.
  • A new fault has occurred (e.g., sensor failure during reset).
  • The ECU detected a persistent problem (e.g., catalytic converter damage).

Light Flashes While Driving

  • This indicates a severe misfire that can damage the catalytic converter.
  • Pull over safely and have the vehicle towed for diagnosis.
  • Do not continue driving—serious engine damage can occur.

Radio or Settings Reset After Battery Disconnect

  • This is normal. Re-enter your radio presets and clock time.
  • Some VE SS models may require a radio code—check your owner’s manual.
  • Adaptive learning (throttle, transmission) may take 50–100 km to relearn.

OBD2 Scanner Won’t Connect

  • Check that the ignition is on (engine off).
  • Ensure the OBD2 port is clean and undamaged.
  • Try a different scanner or update firmware.
  • Verify compatibility—some scanners don’t work with all Holden models.

Preventing Future Check Engine Lights

The best way to avoid resetting the check engine light is to prevent it from coming on in the first place. Here are some proactive tips:

Regular Maintenance

  • Replace spark plugs every 60,000–100,000 km (use OEM or high-quality aftermarket).
  • Change air and fuel filters as recommended.
  • Use quality engine oil and change it on schedule.

Use Quality Fuel

  • Fill up at reputable stations to avoid contaminated fuel.
  • Consider using a fuel system cleaner every 10,000 km.
  • Avoid ethanol-blended fuels if possible (they can damage older fuel systems).

Check the Gas Cap

  • Always tighten the cap until it clicks 3 times.
  • Replace worn or cracked caps—they’re a common cause of EVAP codes.

Avoid Unnecessary Modifications

  • Aftermarket exhausts, intakes, or tuning can trigger false codes.
  • If modifying, use a tuner that adjusts for emissions compliance.
  • Keep records of modifications for inspection purposes.

When to See a Mechanic

While many check engine light issues can be resolved at home, some require professional help. Seek a qualified mechanic if:

  • The light is flashing (indicating a severe misfire)
  • You’re unable to read or clear codes with a scanner
  • The vehicle is running rough, stalling, or losing power
  • You suspect internal engine or transmission problems
  • Emissions testing is due and monitors aren’t ready

A professional diagnostic can save time and prevent costly repairs down the road.
