Fault Status Retrieval
•
Retrieve Fault status by observing the transmission service lamp
1.
Place shift lever in neutral
2.
Set the parking brake
3.
Turn the ignition key on but do not start the engine. If the engine is already running, you can still retrieve fault sta-
tus.
4.
To observe fault status locate the transmission service lamp on the vehicle dash area; if the service lamp is flashing
consistently (more than 2 flashes) the transmission system has an active fault.
Note:
The service lamp merely indicates that there is a fault in the transmission system by flashing consistently; diagnostic pro-
cess will indicate which component/sub-system has failed.
Note:
Under normal conditions at key on the service lamp will flash 2 times indicating that the transmission system is powered
up and functioning properly.
Clearing Faults
•
Any component or sub-system fault will clear itself when the transmission system powers up if a successful repair of
the previous detected fault has been completed.
