Verifying EPB Module Operation

VERIFYING EPB MODULE OPERATION

CAUTION:
The following procedure must be carried out as described.

1. Start engine.

2. Select transmission gear position 'NEUTRAL'.

3. Select transfer case range 'LOW'.

4. Turn engine 'OFF'.

5. Turn ignition 'ON' (engine 'OFF').

6. Use the EPB switch inside the vehicle to apply and release the EPB three times.

NOTE:
If the repair has been successful there will be no abnormal loud screeching noises coming from the EPB Module while carrying out this operation. If there are abnormal screeching noises, the EPB Module may have suffered internal damage and may require replacement. Perform the UNJAMMING THE PARKING BRAKE procedure prior to replacing an EPB Module. Carry out as a separate claim.

NOTE:
If any DTCs have been logged, further investigation is required into possible causes of these DTCs. Refer to the IDS DTC Help Text for further guidance to investigate any DTCs set as a separate claim. If the repair has been successful the DTCs listed at the start of this bulletin will not have logged and the EPB red warning lamp will no longer be flashing.

7. Use IDS to check for DTCs in the EPB Module.

^ If DTCs have been logged or abnormal noises are evident, carry out diagnosis as a separate claim.

^ If no DTCs have been logged or abnormal noises evident, exit the current session.

8. Disconnect the IDS and the Midtronics PSC-550 Vehicle Battery Supply.
