Pinpoint Test Notes

PINPOINT TESTS

Normal Operation
Under normal operation, when the ignition switch is placed in the START position, voltage is supplied from circuit 1050 (LG/PK), through circuit 32 (RD/LB)/33 (WH/PK) to the digital transmission range (TR) sensor. In PARK or NEUTRAL, voltage is supplied from the TR sensor through circuit 1093 (TN/RD) to the starter relay coil. The starter relay coil is supplied ground from the PCM through circuit 325 (DB/OG). When the starter relay is energized, voltage supplied to the relay switch is sent to the starter motor solenoid through circuit 113 (YE/LB). Battery voltage is supplied to the starter motor through circuit 2037 (RD) at all times.

Possible Causes
- An open in circuits 1050 (LG/PK), 32 (RD/LB), 33 (WH/PK), 1093 (TN/RD), 325 (DB/OG) or 113 (YE/LB).
- PCM.
- Digital TR switch.
- Ignition switch.
- Starter motor relay.
- Starter motor.
