5. Also check harness for short to ground and short to power.

Is the inspection result normal?
YES>>GO TO 3.
NO>>GO TO 2.
2.DETECT MALFUNCTIONING PART
Check the following.

- Harness connectors E106, M6
- Harness for open or short between ECM and IPDM E/R

>>Repair open circuit, short to ground or short to power in harness or connectors.
3.CHECK THROTTLE CONTROL MOTOR RELAY INPUT SIGNAL CIRCUIT

1. Check the continuity between IPDM E/R sensor harness connector and ECM harness connector.

Is the inspection result normal?
YES>>GO TO 5.
NO>>GO TO 4.
4.DETECT MALFUNCTIONING PART
Check the following.

- Harness connectors E3, F1
- Harness for open or short between ECM and IPDM E/R

>>Repair open circuit, short to ground or short to power in harness or connectors.
5.CHECK FUSE

1. Disconnect 15A fuse (No. 51) from IPDM E/R.
2. Check 15A fuse for blown.

Is the inspection result normal?
YES>>GO TO 6.
NO>>Replace 15A fuse.
6.CHECK INTERMITTENT INCIDENT
Refer to Intermittent Incident.
