Power Supply to Control Module, No DTCs Stored
Circuit Description
Battery voltage is supplied to the Intelligent Control Suspension Module (ICSM) through fuse F10 in the I/P fuse block, to terminal 6 of the ICSM connector. The voltage is present when the ignition switch is in the ON or START position.
Diagnosis
This test checks for battery output, proper grounding, blown fuses, a faulty ignition switch, and problems in the circuitry.
Cause(s)
- The battery is defective.
- There is a defective ground connection.
- A connector is damaged.
- A wire is broken or shorted.
- A fuse is blown.
- The ignition switch is malfunctioning.
Fall Action
ICS action is disabled during the period of low voltage.
Test Description
The number(s) below refer to step(s) on the diagnostic table
1. This step determines whether there is voltage at the battery and the high current source.
6. This step begins the check for voltage at the ICSM end of the ICS harness.
10. This step checks for a defective ground connection.
11. This is a check for a defective ICSM connector.
Diagnostic Aids
It is very important to perform a thorough inspection of the wiring and the connectors. Failure to do so may result in misdiagnosis, causing part replacement with a reappearance of the malfunction.
