NAV Switch Input Circuit Low (Short)

NAV SWITCH INPUT CIRCUIT LOW (SHORT)





For a complete wiring diagram Consult Diagrams/Electrical

- When Monitored:
The Cluster power-up diagnostics will test the NAV Button A/D port for either an open circuit, short to power or ground, or a stuck button exists.

- Set Condition:
The Instrument Cluster detects excessive current on the NAV MUX Signal circuit. The Cluster will suspend operation of the NAV System until the fault is cleared.





Diagnostic Test

1. CHECK FOR AN ACTIVE DTC
Turn the ignition on.
With the scan tool, record and erase DTCs.
Wait 30 seconds.
With the scan tool, read DTCs.
Does the scan tool display this DTC as active?

Yes

- Go To 2

No

- The condition that caused this code to set is not present at this time. 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.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

2. CLOCK MODULE




With the scan tool, erase DTCs.
Turn the ignition off.
Disconnect the Clock Module harness connector.
Turn the ignition on, with the scan tool, read DTCs.
Does the scan tool display this DTC as active?

Yes

- Replace the Clock Module.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

No

- Go To3

3. (G107) NAV MUX SIGNAL CIRCUIT SHORT TO (G907) EVIC/NAV MUX RETURN CIRCUIT




Turn the ignition off.
Disconnect the Cluster C1 harness connector.
Measure the resistance between the (G107) NAV MUX Signal circuit and the (G907) EVIC/NAV MUX Return circuit.
Is the resistance below 100.0 ohms?

Yes

- Repair the (G107) NAV MUX Signal circuit for a short to the (G907) EVIC/NAV MUX Return circuit.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

No

- Go To4

4. (G107) NAV MUX SIGNAL CIRCUIT SHORT TO GROUND




Turn the ignition off.
Measure the resistance between ground and the (G107) NAV MUX Signal circuit.
Is the resistance below 5.0 ohms?

Yes

- Repair the (G107) NAV MUX Signal circuit for a short to ground.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

No

- Replace the Clock Module.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
