C230B

C230B- NEUTRAL INDICATOR CONTROL CIRCUIT HIGH





For a complete wiring diagram refer to Diagrams/Electrical. Electrical Diagrams


- When Monitored:

With the ignition on and no system undervoltage or overvoltage condition present.

- Set Condition:

The Cluster detects high voltage on the Neutral Indicator Control Circuit when output is on.






Diagnostic Test


1. TEST FOR INTERMITTENT CONDITION

Turn the ignition on.

With the scan tool, record and erase DTCs.

Turn the ignition off, wait 30 seconds then turn the ignition on.

Shift the Transfer Case into neutral.

With the scan tool, read DTCs.

Does the scan tool display: C230B-NEUTRAL INDICATOR CONTROL CIRCUIT HIGH?

Yes

- Go To 2

No

- The condition that caused this code to set is not present at this time. Using the wiring diagram as a guide, inspect the wiring and connectors for an intermittent condition. Operate the system several times and recheck for active DTCs.
- Perform the BODY VERIFICATION TEST-VER 1. Verification Tests



2. (G95) NEUTRAL INDICATOR CIRCUIT VOLTAGE





Turn the ignition off.

Disconnect the Cluster C1 harness connector.

Turn the ignition on.

Measure the voltage of the (G95) Neutral Indicator circuit.

Is there any voltage present?

Yes

- Replace the Cluster.
- Perform the BODY VERIFICATION TEST-VER 1. Verification Tests

No

- Go To 3



3. (G95) 4WD NEUTRAL INDICATOR CIRCUIT SHORT TO GROUND





Turn the ignition off.

Disconnect the Transfer Case Switch harness connector.

Measure the resistance of the (G95) Neutral Indicator circuit to ground.

Is the resistance below 10K ohms?

Yes

- Repair the (G95) Neutral Indicator circuit for a short to ground.
- Perform the BODY VERIFICATION TEST-VER 1. Verification Tests

No

- Go To 4



4. (G95) 4WD NEUTRAL INDICATOR CIRCUIT OPEN





Measure the resistance of the (G95) Neutral Indicator Control circuit between the Transfer Case Switch harness connector and the Cluster C1 harness connector.

Is the resistance above 5.0 ohms?

Yes

- Repair the open (G95) Neutral Indicator circuit for an open.
- Perform the BODY VERIFICATION TEST-VER 1. Verification Tests

No

- Replace the Transfer Case Switch.
- Perform the BODY VERIFICATION TEST-VER 1. Verification Tests
