CIRCUIT DESCRIPTION
The PCM has the ability to disable 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 lime.

The PCM controlled starter system consists of the following components:
^ Starter enable relay
^ The transaxle range/park neutral position switch
^ The ignition switch
^ The starter solenoid
^ The PCM

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. For starter motor diagnosis and on-vehicle service, refer to A Diagnostic System Check - Starting and Charging.

Check for the following conditions:
^ Poor connection at the PCM, the starter enable relay, the transaxle range/PNP switch, the ignition or the starter solenoid.
Inspect harness connectors for the following conditions:
- Backed out terminals
- Improper mating
- Broken locks
- Improperly formed or damaged terminals
- Poor terminal to wire connection
^ Damaged harness.
Inspect the wiring harness for damage.
^ Either of the following conditions can cause the PCM to disable starter operation:
- The engine is running.
- The starter has been continuously engaged for longer than 15 seconds.
- A correct VTD password has not been received from the VTD system.
