Info - GM Oil Life System - Resetting
| Subject: | GM Oil Life System™ -- Resetting |
| Models: | 2002 Chevrolet and GMC S/T Utility Models (TrailBlazer, Envoy) |
| 2002 Oldsmobile Bravada |
These vehicles have an oil life monitor. The GM Oil Life System™ will show when to change the engine oil and oil filter. The GM Oil Life System™ must be reset after changing the engine oil and oil filter.
Resetting Procedure
The current Owner's Manual contains the following reset procedure:
- Turn the ignition to RUN with the engine off.
- Fully press and release the accelerator pedal three times within five seconds. If the CHANGE ENG OIL light flashes for five seconds, the system is reset. If the light does not flash, repeat the procedure.
However, it has been found that after completing the reset procedure, the CHANGE ENG OIL light does not flash as stated in the vehicle Owner's Manual.
If the CHANGE ENG OIL light goes out after the reset procedure and does not return after the next ignition cycle, then the system has been reset.
If the vehicle is equipped with a Driver Information Center (DIC), then reset confirmation can also be done by verifying that the Engine Oil Life percentage value has reset to 100%.
Use the above information to prevent the inadvertent replacement of the instrument cluster if there are comments that the oil life reset feature does not work.
