Theory Of Operation
WARNING: This page is about a different variant/trim than selected.
This diagnostic checks for the proper response of the gear shift actuator 5th-R to the Transmission Controller Module (TCM) engage command. The gear shift actuator 5th-RV is controlled by the TCM via the electrovalves PPV1 and PPV2. This diagnostic checks the position sensor 5th-R output to confirm that the gear shift actuator 5th-R has moved to the proper position when it is controlled by the TCM and that the gear has been engaged.
