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 not start the engine.

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.

2 times off on

To Retrieve Inactive (Intermittent) Codes: Start with the key in the on position. Turn the key off and on four times within five seconds ending with the key in the on position.

4 times

off on

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

5.Observe the sequence of flashes on the indicator lamp and record the codes. A one to two second pause separates each stored code, and the sequence automatically repeats after all codes have been flashed.

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.)

1.Place the shift lever in neutral.

2.Set the parking brakes.

3.Turn the ignition key on but do not start the engine.

4.Start with the key in the on position. Turn the key off and on six times within five seconds ending with the key in the on position.
