B210E

B210E - OCM BATTERY VOLTAGE HIGH





For a complete wiring diagram refer to Diagrams/Electrical.

- When Monitored:While the CAN bus ignition status received is RUN or SNA (Signal Not Available), the module checks the Fused B(+) circuit voltage input range.

- Set Condition:If the Occupant Classification Module (OCM) detects battery voltage 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.

With the scan tool, read OCM 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 OCM battery voltage.

Is the battery voltage greater than 24.0 ± 0.25 volts?

Yes

- Go To 3

No

- Replace the OCM.
- Perform AIRBAG VERIFICATION TEST. Airbag System 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 OCM.
- Perform AIRBAG VERIFICATION TEST. Airbag System 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.

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.
