B210F-LOSS OF BATTERY VOLTAGE







- 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. CHECK FOR AN ACTIVE DTC
1. Turn the ignition on.
2. With the scan tool, read DTCs

Does the scan tool display this DTC as active?

Yes

- Go To 2

No

- Test complete, the condition or conditions that originally set this DTC are not present at this time. Using the wiring diagrams as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals, and correct pin tension.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

2. CHECK THE (A944) FUSED B(+) CIRCUIT FOR AN OPEN OR SHORT TO GROUND





NOTE: Inspect related TIPM fuses before proceeding with this diagnostic procedure. Repair as necessary.

1. Disconnect the Cluster C1 harness connector.
2. Turn the ignition on.
3. Measure the voltage of the (A944) Fused B(+) circuit.

Is the voltage above 10 volts?

Yes

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

No

- Using the wiring diagram/schematic as a guide, repair the (A944) Fused B(+) circuit for an open or short to ground.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
