Reading Diagnostic Trouble Codes

Fuel Injection Fault Display Unit:





READING FAULT CODES (USA only)
The Engine Control Module (ECM) is capable of storing fault codes. For U.S. vehicles, these fault codes may be read by switching the ignition switch to position II and observing the fuel injection fault display unit, which is located underneath the right hand front seat, adjacent to the ECM.

NOTE: Image shows display unit with trim removed.

If no codes are present, the display will appear blank. A constantly lit Check Engine warning light indicates that a fault is present.

1. Put the ignition switch in position 0 and wait till the load relay drops out.
2. Put the ignition switch in position II. The display will be blank if no other faults exist. If other codes exist, the next fault code will be displayed.
3. If multiple faults exist, repeat steps 1 through 3 until all faults are cleared.

Code 02 indicates that the ECM has just been reconnected. Switch the ignition switch to position II to clear code 02.

For non-U.S. vehicles (not equipped with a fuel injection fault display), the Lucas diagnostic equipment, part number 60600965, is recommended for reading fault codes.
