Starter Inhibit Relay Circuit Diagnosis

CIRCUIT DESCRIPTION

The PCM has the ability to disable the starter operation if conditions inappropriate for starter operation exist. The PCM disables the starter if the engine is running, if a correct VTD password is not received from the VTD system, or if the vehicle operator attempts to engage the starter for an extended period of time. The PCM controlled starter system consists of the following components:
^ The starter enable relay
^ Transaxle range or Park/neutral Position (PNP) switch
^ The ignition switch
^ The starter solenoid
^ The PCM

Steps 1 - 8:

Steps 7 - 20:

Steps 21 - 32:

DIAGNOSTIC AIDS
The PCM Controlled Starter Diagnosis table is intended to identify electrical malfunctions that can occur with the system. For additional system diagnosis, refer to A Diagnostic System Check - Starting and Charging in Starting and Charging. Testing and Inspection

Check for the following conditions:
^ A faulty connection at the PCM, the starter enable relay, the PNP switch, the ignition switch, or the starter solenoid
Inspect the harness connectors for the following conditions:
- Backed out terminals
- Improper mating
- Broken locks
- Improperly formed or damaged terminals
- Faulty terminal-to-wire connections
^ Inspect the wiring harness for damage.
^ Either of the following conditions can cause the PCM to disable the starter operation:
- The engine is running.
- The starter has been continuously engaged for more than 30 seconds.
- A correct password has not been received from the VTD system.
