Fault Code Retrieval and Clearing

RETRIEVING FAULT CODES CLEARING FAULT CODES

Note: Retrieve Bendix™ VORAD® system fault codes by enabling the VORAD system’s self-diagnostic mode.

You can also use a PC-based Service Tool, such as ServiceRanger 2.8, or a Pro-Link tool, to retrieve VORAD system fault codes.

1.Put the vehicle in neutral.

2.Set the parking brake.

3.To activate Failure Display Mode, press in and hold the Driver Display Unit “VOLUME” knob while turning the key on.

Note: For software versions 013 and higher, hold “VOLUME” knob in for 8 seconds.

4.Wait until the Driver Display Unit’s red “FAIL” indicator light begins flashing two-digit fault codes and release the volume knob. If no fault codes are found, the Driver Display Unit will flash a code 41. At the conclusion of flashing the fault codes, the system will flash a code 41.

5.TO READ ACTIVE FAULT CODES: Position the Driver Display Unit “RANGE” knob to the left of center and only active codes will be sent to the “FAIL” indicator light.

6.TO READ INACTIVE FAULT CODES: Position the Driver Display Unit “RANGE” knob to the right of center and only inactive codes will be sent to the “FAIL” indicator light.

7.Observe the sequence of flashes on the indicator lamp and record the codes. A one to two second pause separates each stored code, and at the conclusion of flashing the fault codes, the system will flash a code 41. The sequence automatically repeats after all codes have been flashed.

1.Inactive fault codes must be cleared using a PC-based Service Tool, such as ServiceRanger 2.8, or a Pro-Link tool.

2.Active fault codes change to inactive fault codes when the fault has been corrected. Clear inactive fault codes.

3.Turn key off and allow system to power down.

4.Start vehicle and verify no fault codes reoccur.
