Vehicle Service Note


After all diagnosis and repairs are completed, road test the vehicle to ensure proper ABS operation and that the SERVICE ABS light does not illuminate. If the Tech 1 was used for diagnosis, disconnect it from the ALDL connector and turn the ignition Off before road testing the vehicle. This is required to reset the EBCM, it is disabled during Tech 1 diagnostics and does not reset until serial data communication is stopped and ignition power is lost.
