B210E-BATTERY VOLTAGE HIGH

For a complete wiring diagram REFER to DIAGRAMS/ELECTRICAL .

Theory of Operation


The Occupant Restraint Controller module (ORC) receives power from both a battery and ignition fed input circuit from the Totally Integrated Power Module (TIPM). These circuits power the ORC and the capacitors used to initiate the squib deployment circuits in the event of collision detection.


- When Monitored:
The Occupant Restraint Module (ORC) monitors the battery voltage and ignition continuously.

- Set Condition:
This code is set immediately after the Occupant Restraint Module (ORC) detects that voltage on the battery voltage supply circuits is 17.45 v +/- 1.45 v or more for greater than 15 seconds.







Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding.Restraints System Pre-Diagnostic Procedure.


Diagnostic Test

NOTE: Ensure the battery is fully charged.


1. CHECK PCM FOR CHARGING SYSTEM DTC
With the scan tool, read Powertrain Control Module DTC's.
Are there any Charging System DTC's set in the Powertrain/Engine Control Module?

Yes


- Diagnose and repair the DTC(s).

No


- Go To 2


2. DETERMINE ACTIVE OR STORED DTC
Turn the ignition on.
With the scan tool, read all active ORC DTCs.
Is the DTC active or stored?

ORC - ACTIVE DTC


- Go To 3


ORC - STORED DTC


- Perform *RESTRAINTS SYSTEM INTERMITTENT TEST.Restraints System Intermittent Test.


3. CHECK VOLTAGE TO THE ORC

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

Disconnect the ORC harness connectors.
Connect the Load Tool ORC 8443-28 Adaptor to the ORC connectors.

NOTE: Check connectors - Clean and repair as necessary.


WARNING: To avoid serious or fatal injury, turn the ignition on, then reconnect the battery.

Measure the voltage on the (A27) Fused B+ circuit.
Is the voltage 17.45 v +/- 1.45 v or more?

Yes

WARNING: If the Occupant Restraint Controller (ORC) 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.

- Repair the (A27) Fused B+ circuit.
- Perform *RESTRAINTS SYSTEM VERIFICATION TEST. Restraints System Verification Test.


No


- Replace the ORC.
