Instructions
Things You’ll Need
Wrench
Ignition key
OBDl or ll scanner
1. Disconnect your battery cables from the battery posts with a 6-pt. closed wrench in the size appropriate for the battery bolts. Remove the negative (black) cable first. Leave the battery disconnected for several minutes, according to Allpar.com. Reconnect, this time starting with the positive cable, and crank the engine. The code should be gone.
2. Crank the Jeep. Drive it forward, then backwards, and shut off. Repeat this procedure three times. The codes should clear on the fourth crank.
3. Use a OBDl or OBDll scan tool. Plug the tool into your Jeep’s ALDL (Assembly Line Diagnostic Link), a small, rectangular electrical port usually located under the dash. Turn the key to the “on” position. Scan the computer for codes and select the option to clear the codes.
4. Wait for the code to clear itself automatically. Once the component is fixed, the check engine light disappears after several successful ignitions. The code is then stored for a while. If the engine continues to start and run without a re-occurrence of the original problem, the code is wiped out.
Considering it’s made by a GM company, I would assume the standard practice here works there…
Turn key to on, but do not start…
Pump gas peddle three times…
Press and hold brake peddle till the service light blinks and then goes out…
Start the car to make sure the light was reset…
Or…
Turn to on…
Hold trip reset button…
Start car
keep holding trip reset till the light on the dash goes out…
Hopefully one of those works, but they’re just kinda the ‘try this’ until someone who knows chimes in.
