Introduction
Fault Codes Retrieval/Clearing
Retrieving Fault Codes
Retrieve CEEMAT fault codes by enabling the CEEMAT
system’s self-diagnostic mode.
Note: You can also use a diagnostic scan tool, such as the
MPSI Pro Link Main, to retrieve CEEMAT fault codes. Refer to
the OEM’s documentation for more information.
1. Place the shift lever in neutral.
2. Set the parking brakes.
3. Turn the ignition key on but do
4. To Retrieve Active Codes: Start with the key in the on
position. Turn the key off and on two times within five
seconds ending with the key in the on position.

Clearing Fault Codes
The following procedure clears all inactive (intermittent) fault
codes from the ECU’s memory. (Active fault codes are
automatically cleared when the fault has been corrected.)

After a brief pause, the service transmission indicator
lamp begins flashing two-digit fault codes.
