Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 9 - ENGINE -
DIAGNOSIS AND TESTING).
Diagnostic Test
1.VERIFY ASD DTC
NOTE: Diagnose P0685 - Auto Shutdown Relay Control Circuit first if it set along with this DTC.
With a scan tool, erase the DTC.
Attempt to start the engine. If the engine will not start, crank the engine for at least 15 seconds. It may be neces-
sary to repeat several times.
Does the DTC reset?

When Monitored:
Ignition on.
Set Condition:
When the PCM recognizes Brake Switch No.2 voltage is not equal to the applied value at the PCM when
Brake Switch No.1 is applied. This could be a normal condition. If this condition is seen repeatedly by the PCM
the fault is set. Cruise will not work for the rest of the key cycle.
