C230A

C230A-NEUTRAL INDICATOR CONTROL CIRCUIT LOW





For a complete wiring diagram, refer to the Wiring Information Electrical Diagrams

- When Monitored:
With the ignition on and no system undervoltage or overvoltage condition present.

- Set Condition:
The Cluster detects low voltage on the (G95) Neutral Indicator Control Circuit when output is off.





1. TEST FOR INTERMITTENT CONDITION
1. Turn the ignition on.
2. With the scan tool, record and erase DTCs.
3. Turn the ignition off, wait 30 seconds then turn the ignition on.
4. Shift the Transfer Case into neutral.
5. With the scan tool, read DTCs.

Does the scan tool display: C230A-NEUTRAL INDICATOR CONTROL CIRCUIT LOW?

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. Body Verification Test

2. (G95) 4WD NEUTRAL INDICATOR CIRCUIT RESISTANCE TO GROUND




1. Turn the ignition off.
2. Disconnect the Cluster C1 connector.
3. Measure the resistance between ground and the (G95) Neutral Indicator circuit.

Is the resistance below 5.0 ohms?

Yes

- Go To 3

No

- Go To 4

3. (G95) NEUTRAL INDICATOR CIRCUIT SHORT TO GROUND




1. Disconnect the Transfer Case Switch harness connector.
2. Measure the resistance between ground and the (G95) Neutral Indicator circuit.

Is the resistance below 5.0 ohms?

Yes

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

No

- Replace the Transfer Case Switch.
- Perform the BODY VERIFICATION TEST. Body Verification Test

4. (G95) NEUTRAL INDICATOR CIRCUIT OPEN




1. Disconnect the Transfer Case Switch harness connector.
2. Measure the resistance of the (G95) Neutral Indicator 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. Body Verification Test

No

- Replace the Cluster.
- Perform the BODY VERIFICATION TEST. Body Verification Test
