B210E

B210E - OCM BATTERY VOLTAGE HIGH





For a complete wiring diagram Consult 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

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

WARNING: If the Occupant Classification Module (OCM) is dropped at any time, it must be replaced. Failure to take the proper precautions can result in accidental airbag deployment and serious or fatal injury.

- Replace the Passenger Seat Assembly.
- 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

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

WARNING: If the Occupant Classification Module (OCM) is dropped at any time, it must be replaced. Failure to take the proper precautions can result in accidental airbag deployment and serious or fatal injury.

- Replace the Passenger Seat Assembly.
- 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

- Diagnose and repair the DTC(s).

No

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