Diagnosis/Correction Cranks/No Start

The PASSKey system is allowing the car to crank, so the lock cylinder, key and wiring to the PASSKey module are OK.

The condition may be an open or short to ground or voltage between the PASSKey module and PCM, in circuit 229. Sometimes the condition will have occurred with the engine running and a Code E58 or E058 will set.

To try to duplicate the intermittent condition, clear codes, exit diagnostics, and start the engine. Check circuit 229 connections or wiring between the PASSKey module and PCM. If the condition is duplicated (229 open or shorted), a message will turn on.

See Section 6E-A to check for fuel injection causes of crank/no-start.

IMPORTANT:

^ When diagnosing intermittent no start/no crank, also check items such as battery, starter, neutral safety backup switch (NSBU or PRNDL switch).

^ When diagnosing crank/no start, check for PCM codes that would indicate ignition or fuel injection causes.
