YES>>GO TO 2.
NO>>Repair the terminal and connector.
2.CHECK HARNESS FOR OPEN CIRCUIT

1. Disconnect the connector of IPDM E/R.
2. Check the resistance between the IPDM E/R harness connector terminals.

   IPDM E/R harness connector | Resistance (Ω)
   Connector No. | Terminal No.
   E6 | 40 | 39 | Approx. 108 – 132

Is the measurement value within the specification?
YES>>GO TO 3.
NO>>Repair the IPDM E/R branch line.
3.CHECK POWER SUPPLY AND GROUND CIRCUIT
Check the power supply and the ground circuit of the IPDM E/R. Refer to Diagnosis Procedure.
Is the inspection result normal?
