C230A- NEUTRAL INDICATOR CONTROL CIRCUIT LOW





For a complete wiring diagram Consult Diagrams/Electrical

- When Monitored:
With the ignition on.

- Set Condition:
The Cluster detects low voltage on the Neutral Indicator Control Circuit.





Diagnostic Test

1. DTC IS ACTIVE
Ignition on, engine not running.
With the scan tool, clear the DTCs in the Instrument Cluster.
Shift the Transfer Case into neutral for 30 seconds.
With the scan tool, read the Instrument Cluster DTCs.
Does this DTC reset?

Yes

- Go to 2

No

- Go to 5


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




Turn the ignition off to the lock position
Disconnect the Instrument Cluster C3 harness connector.
Measure the resistance between ground and the (G95) 4WD Neutral Indicator circuit.
Is the resistance below 5.0 ohms?

Yes

- Go to 3

No

- Go to 4

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




Disconnect the Transfer Case Selector Switch harness connector.
Measure the resistance between ground and the (G95) 4WD Neutral Indicator circuit.
Is the resistance below 5.0 ohms?

Yes

- Repair the (G95) 4WD Neutral Indicator circuit for a short to ground.
- Perform the TRANSFER CASE VERIFICATION TEST-VER 1.

No

- Replace the Transfer Case Selector Switch.
- Perform the TRANSFER CASE VERIFICATION TEST-VER 1.

4. (G95) 4WD NEUTRAL INDICATOR CIRCUIT OPEN




Disconnect the Transfer Case Selector Switch harness connector.
Measure the resistance of the (G95) 4WD Neutral Indicator circuit between the Transfer Case Selector Switch harness connector and the Instrument Cluster C3 harness connector.
Is the resistance above 5.0 ohms?

Yes

- Repair the open (G95) 4WD Neutral Indicator circuit.
- Perform the TRANSFER CASE VERIFICATION TEST-VER 1.

No

- Replace the Instrument Cluster.
- Perform the TRANSFER CASE VERIFICATION TEST-VER 1.

5. INTERMITTENT WIRING AND CONNECTORS
The conditions necessary to set this DTC are not present at this time.
Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
While monitoring the scan tool data relative to this circuit, wiggle test the wiring and connectors.
Look for the data to change or for the DTC to reset during the wiggle test.
Were any problems found?

Yes

- Repair as necessary.
- Perform the TRANSFER CASE VERIFICATION TEST-VER 1.

No

- Test complete.
