1.CHECK THROTTLE CONTROL MOTOR POWER SUPPLY
2.CHECK THROTTLE CONTROL MOTOR POWER SUPPLY CIRCUIT
- Disconnect ECM harness connector.
- Disconnect IPDM E/R harness connector.
- Check the continuity between ECM harness connector and IPDM E/R harness connector.
+ | − | Continuity |
ECM | IPDM E/R |
Connector | Terminal | Connector | Terminal |
F51 | 5 | F35 | 73 | Existed |
E16 | 153 |
- Also check harness for short to ground.
Is the inspection result normal?
Perform the trouble diagnosis for power supply circuit. Repair or replace error-detected parts.
3.CHECK THROTTLE CONTROL MOTOR INPUT SIGNAL
Check the voltage between ECM harness connector and ground as per the following conditions.ECM | Condition | Voltage (Approx.) |
+ | − |
Connector | Terminal | Connector | Terminal |
F51 | 24 | E16 | 160 | Ignition switch: OFF | 0 V |
Ignition switch: ON | Battery voltage |
Is the inspection result normal?
.
4.CHECK THROTTLE CONTROL MOTOR INPUT SIGNAL CIRCUIT
- Turn ignition switch OFF.
- Disconnect ECM harness connector.
- Disconnect IPDM E/R harness connector.
- Check the continuity between ECM harness connector and IPDM E/R harness connector.
+ | − | Continuity |
ECM | IPDM E/R |
Connector | Terminal | Connector | Terminal |
F51 | 24 | F42 | 93 | Existed |
- Also check harness for short to ground and to power.
Is the inspection result normal?
Repair or replace error-detected parts.
