NO>>GO TO 2.
2.CHECK POWER SUPPLY CIRCUIT

1. Turn the ignition switch OFF.
2. Disconnect IPDM E/R connector.
3. Check voltage between the IPDM E/R harness connector and the ground.

   Terminals | Voltage (Approx.)
   (+) | (−)
   IPDM E/R
   Connector | Terminal | Ground
   E4 | 1 | Battery voltage

Is the measurement value normal?
YES>>GO TO 3.
NO>>Repair the harness or connector.
3.CHECK GROUND CIRCUIT
Check continuity between the IPDM E/R harness connectors and the ground.

IPDM E/R | Ground | Continuity
Connector | Terminal
E5 | 12 | Existed
E6 | 41

Does continuity exist?
YES>>INSPECTION END
NO>>Repair the harness or connector.
