For a complete wiring diagram refer to Diagrams/Electrical.

- When Monitored:

Continuously.

- Set Condition:

If the Battery Voltage Feed indicates OFF for 1 second, then fault is written directly to EEPROM. If the battery voltage feed is restored in under 36 miles (58 km), then the EEPROM is cleared.





1. IOD FUSE NOT INSTALLED

Inspect the IOD Fuse.

Is the IOD fuse installed?

Yes

- Go To2

No

- Install the IOD fuse.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

2. IOD FUSE OPEN

Turn the ignition off.

Inspect the IOD fuse in the PDC.

Is the IOD fuse open?

Yes

- Using the wiring diagram/schematic as a guide, inspect the wiring and connectors for a short to ground condition.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

No

- Go To3

3. CHECK THE (A944) BATTERY VOLTAGE FEED FOR AN OPEN





Disconnect the Instrument Cluster C1 harness connector.

Turn the ignition on.

Measure the voltage of the (A944) Battery Voltage Feed circuit.

Is the voltage above 10 volts?

Yes

- Replace the Instrument Cluster.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

No

- Using the wiring diagram/schematic as a guide, repair the (A944) Battery Voltage feed circuit for an open.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
