System Diagnosis



SYSTEM DIAGNOSIS

Use the following table to determine the procedure to use. If engine won't crank, or cranks but won't start, enter ECM Diagnostic Mode and check for display of Code 46 or 53.

Note: Code 46 or 53 will be stored for up to 50 Vehicle starts. Therefore after diagnosis is complete, be sure to clear ECM codes.

There are four "No Start" conditions that can occur on a vehicle equipped with PASS Key that may appear to be caused by PASS Key. The four conditions are given in the following table. The first of these is almost certain to be a PASS Key problem. The second and third can be caused by other systems on the vehicle. The fourth symptom is definitely not related to PASS Key.
