Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. See CONNECTOR INSPECTION PROCEDURE .

Are all connectors good?

1. Yes:  Go to next step.
2. No: Repair or replace it.

1. Turn ignition switch to OFF and disconnect OTS connector.
2. Measure resistance between the terminals 1 and 2 of OTS connector.

Is resistance within specification?

1. Yes:  Go to next step.
2. No: Replace OTS.

1. Turn ignition switch to OFF position and disconnect OTS connector.
2. Turn ignition switch to ON position.
3. Measure voltage between terminal 1 of the OTS harness connector and chassis ground.

   Specification (Voltage): approximately 5V

   Is voltage within specification?

1. Yes:  Go to next step.
2. No: Repair open or short to chassis ground in harness.

1. Turn ignition switch to OFF position, and then disconnect OTS and ECM connectors.
2. Measure resistance between terminal 2 of the OTS harness connector and chassis ground.
3. Measure resistance between terminal 1 and 2 of the OTS harness connector.

   Specification (Resistance): infinite
