Diagnostic Test


1. RELATED DTC(S) PRESENT IN PCM

Ignition on, engine not running.

With the scan tool, select View DTCs in the Powertrain Control Module.

Are there any charging system or related battery voltage DTCs present in the PCM?

Yes

- Refer to the appropriate symptom in the Driveability category.

No

- Go to 2



2. DTC STATUS IS ACTIVE

With the scan tool, select View DTCs in the Steering Control Module.

Is the DTC status Active at this time?

Yes

- Go to 3

No

- The condition that caused this symptom is currently not present. Check for an intermittent condition by inspecting the related wiring harness for chafed, pierced, pinched, and partially broken wires. Also, inspect the related connectors for broken, bent, pushed out, spread, corroded, or contaminated terminals. Repair as necessary.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test



3. (A913) FUSED B(+) CIRCUIT HIGH RESISTANCE

Turn the ignition off.

Remove the Steering Control Module.

Turn the ignition on.

Using a 12-volt test light connected to ground, check the (A913) Fused B(+) circuit in the Steering Control Module harness connector.


NOTE: The test light must illuminate brightly. Compare the brightness to that of a direct connection to the battery.

Does the test light illuminate brightly?

Yes

- Go to 4

No

- Repair the (A913) Fused B(+) circuit.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test



4. (Z910) GROUND CIRCUIT HIGH RESISTANCE

Using a 12-volt test light connected to 12-volts, check the (Z910) Ground circuit in the Steering Control Module harness connector.


NOTE: The test light must illuminate brightly. Compare the brightness to that of a direct connection to the battery.

Does the test light illuminate brightly?

Yes

- Replace the Steering Control Module.

No

- Repair the (Z910) Ground circuit.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
