B210E-BATTERY VOLTAGE HIGHB210E - Battery Voltage High:
WHEN MONITORED
While the CAN bus ignition status received is RUN or Signal Not Available (SNA), the module checks the (A27) Fused B(+) circuit voltage input range.
SET CONDITION
If the module detects that the battery voltage is greater than or equal to 24.25 volts ± 0.25 volts for 10 seconds.
POSSIBLE CAUSES
- Vehicle charging system
- Occupant classification module (OCM)
Diagnostic Test
1. CHECK FOR AN ACTIVE DTC
Turn the ignition on, then off, and then on again.
With the scan tool, read OCM DTCs.
Q: 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.
Q: Is the battery voltage greater than 24.0 volts?
YES: Go To 3
NO: Replace the OCM. Perform OCS VERIFICATION TEST - VER 1. OCS 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.
Q: Does the scan tool display any Charging System related DTCs?
YES: Diagnose and repair the DTCs.
NO: Replace the OCM. Perform OCS VERIFICATION TEST - VER 1. OCS 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.
Q: Does the scan tool display any ACTIVE DTCs?
YES: Select appropriate symptom from Symptom List.
NO: No problem found at this time. Perform OCS SYSTEM VERIFICATION TEST VER - 1 OCS Verification Test Erase all codes before returning vehicle to customer.
