Fault Code Retrieval and Clearing
RETRIEVING 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 fl ashing two-digit fault codes and release
the volume knob. If no fault codes are found, the Driver
Display Unit will fl ash a code 41. At the conclusion of
fl ashing the fault codes, the system will fl ash 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 fl ashes on the indicator lamp
and record the codes. A one to two second pause
separates each stored code, and at the conclusion of
fl ashing the fault codes, the system will fl ash a code 41.
The sequence automatically repeats after all codes have
been fl ashed.
CLEARING FAULT CODES
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.
