B210E-BATTERY VOLTAGE HIGH





For a complete wiring diagram refer to Diagrams/Electrical.

- When Monitored:

While the CAN bus ignition status received is RUN or signal not available, the module checks the (F201) Fused Ignition Switch Output (RUN/START) circuit.

- Set Condition:

If the module detects that the battery voltage is greater than or equal to 24.25 ± 0.25 volts for 10 seconds.





Diagnostic Test

1. CHECK FOR AN ACTIVE DTC

Turn the ignition on, then off, and then on again.

With the scan tool, read ORM DTCs.

Does the scan tool display active: B210E-BATTERY VOLTAGE HIGH?

Yes

- Go To 2

No

- Go To 4

2. CHECK THE BATTERY VOLTAGE TO THE OCCUPANT CLASSIFICATION MODULE

With the scan tool in Data Display, read ORC battery voltage.

Is the battery voltage greater than 24.25 volts ± 0.25 volts?

Yes

- Go To 3

No

- Replace the ORC.
- Perform ORC VERIFICATION TEST-VER 1. Occupant Restraint Controller (ORC) Verification Test

3. CHECK FOR CHARGING SYSTEM RELATED DTCs IN THE POWERTRAIN CONTROL MODULE (PCM)

With the scan tool in ECU View, select PCM and check for any Charging System related DTCs.

Does the scan tool display any Charging System related DTCs?

Yes

- Diagnose and repair the DTCs.

No

- Replace the ORC.
- Perform ORC VERIFICATION TEST-VER 1. Occupant Restraint Controller (ORC) Verification Test

4. TEST FOR INTERMITTENT CONDITION

With the scan tool, record and erase all DTCs from all Airbag modules.

If any ACTIVE codes are present they must be resolved before diagnosing any stored codes.

WARNING: To avoid personal injury or death, turn the ignition off, disconnect the battery and wait two minutes before proceeding.

Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.

Look for chafed, pierced, pinched, or partially broken wires and broken, bent, pushed out, spread, corroded, or contaminated terminals.

The following additional checks may assist you in identifying a possible intermittent problem.

Reconnect any disconnected components and harness connector.

WARNING: To avoid personal injury or death, turn the ignition on, then reconnect the battery.

With the scan tool, monitor active codes as you work through the following steps.

WARNING: To avoid personal injury or death, maintain a safe distance from all airbags while performing the following steps.

Wiggle the wiring harness and connectors of the related airbag circuit or component.

If codes are related to the Driver Airbag circuits, rotate the steering wheel from stop to stop.

If only stored codes return, continue the test until the problem area has been isolated.

In the previous steps you have attempted to recreate the conditions responsible for setting the active DTC in question.

Does the scan tool display any ACTIVE DTCs?

Yes

- Select appropriate symptom from Symptom List.

No

- No problem found Erase all codes before returning vehicle to customer.
