C230B

C230B-NEUTRAL INDICATOR CONTROL CIRCUIT HIGH







- 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.





1. DTC IS ACTIVE
1. Ignition on engine not running.
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.

Is the DTC status Active at this time?

Yes

- Go To 2

No

- Go To 5

2. (G95) NEUTRAL INDICATOR CIRCUIT VOLTAGE




1. Turn the ignition off to the lock position.
2. Disconnect the Cluster C1 harness connector.
3. Ignition on engine not running.
4. Measure the voltage of the (G95) Neutral Indicator circuit.

Is there any voltage present?

Yes

- Replace the Cluster Cabin Node (CCN).
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Go To 3

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




1. Turn the ignition off to the lock position.
2. Disconnect the Transfer Case Switch harness connector.
3. 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. Body Verification Test.

No

- Go To 4

4. (G95) 4WD NEUTRAL INDICATOR CIRCUIT OPEN




1. 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. Body Verification Test.

No

- Replace the Transfer Case Selector Switch.
- Perform the TRANSFER CASE VERIFICATION TEST. Transfer Case Verification Test.

5. INTERMITTENT WIRING HARNESS AND CONNECTORS
1. The conditions necessary to set this DTC are not present at this time.
2. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
3. Wiggle test the wiring harness and connectors while monitoring the scan tool data relative to this circuit.
4. Look for the data to change or for the DTC to reset during the wiggle test.
5. While monitoring the scan tool data relative to this circuit, move the selector switch to each position several times.
6. Look for the data to change other than as expected or for the DTC to reset.

Were any problems found?

Yes

- Repair as necessary.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Test complete.
