I just had an oil change and the guy turned the key on (did not start car). Pumped the gas pedal three times simultaneous. Repeated with key off.
You can disconnect the negative battery cable, wait a couple minutes then reconnect the cable. This will clear the codes and reset the check engine light but, if the reason the light came on isn't fixed the light will come back on soon.
With a scan tool.
Probably because you need to check the engine.
The light is reset with a scan tool after the repair. There is not a button.
Use a code reader to find out why the check engine light is on.
To reset the oil light in a 2002 Oldsmobile Bravada, first turn the ignition key to the "On" position without starting the engine. Then, press the accelerator pedal three times within five seconds. This should reset the oil change light. Finally, turn off the ignition and restart the vehicle to ensure the light is no longer illuminated.
If the check engine light is on, use a code scanner to find out why.
take it to autozone and have it scanned
After repairing the cause of the code, you clear the code with a scan tool.
Dome light fuse for 2004 Bravada is fuse#4 (10amp) in fuse box underneath back seat on driver's side
The engine computer has detected a malfunction and set a code.
After you have fixed the issue that caused your check engine light to come on, you can use a pocket scanner to erase the code, but this causes your computer to reset and during an inspection will cause many unready codes failing the inspection. You must drive your bravada 5 miles at a non-stop 55miles an hour to clear the computer, sometimes it just takes a few days of driving to get the reset to clear all codes but normally the 5 miles at 55mph will do the trick.
