Diagnosis Procedure 2
CAUTION:
Before testing, perform the following procedure to ensure the engine cannot start.
- Remove fuel pump fuse.
- Crank or start the engine (where possible) until the fuel pressure is depleted.
- CHECK STARTER MOTOR MAGNETIC SWITCH CIRCUIT
- Turn ignition switch OFF.
- Disconnect starter motor connector F28.
- Shift transmission into park or neutral.
- Check voltage between starter motor harness connector F28 terminal S and ground with the ignition switch in START.
(+) (-) Condition Voltage Connector Terminal F28 S Ground Ignition switch in START Battery voltage Is battery voltage present?
YES: Magnetic switch circuit is OK. Further inspection is necessary. Refer to "TROUBLE DIAGNOSIS WITH GR8-1200 NI " or "TROUBLE DIAGNOSIS WITHOUT GR8-1200 NI ".
NO: GO TO 2
- CHECK CONNECTOR
- Turn ignition switch OFF.
- Check the IPDM E/R harness connector E44 and starter motor harness connector F28 for damage, bent pins and loose connections.
Is the inspection result normal?
YES: GO TO 3
NO: Repair the terminal and connector.
- CHECK HARNESS CONTINUITY (OPEN CIRCUIT)
- Disconnect IPDM E/R connector E44 and starter motor connector F28.
- Check continuity between starter motor harness connector F28 terminal S and IPDM E/R harness connector E44 terminal 19.
Connector Terminal Connector Terminal Continuity F28 S E44 19 Yes - Check continuity between starter motor harness connector F28 terminal S and ground.
Connector Terminal Ground Continuity F28 S No Are the continuity test results as specified?
YES: Further inspection is necessary. Refer to "TROUBLE DIAGNOSIS WITH GR8-1200 NI " or "TROUBLE DIAGNOSIS WITHOUT GR8-1200 NI ".
NO: Repair the harness.
