Bendix ® RDU ™ Communication Problems
If the ABS ECU does not respond to the RDU ™ tool’s
request for diagnostic trouble codes, the RDU ™ tool will
illuminate each red LED in a clockwise pattern. This pattern
indicates the loss of communication and will continue until
the ABS ECU responds and communication has been
re-established.
Possible sources of communication problems are:
1. A problem with the J1587 link at the in-cab off-board
diagnostic connector (9 or 6 Pin).
2. The ECU does not support PID194.
3. No power is being supplied to the ECU and/or the
diagnostic connector.
4. The J1587 bus is overloaded with information and the
RDU can not arbitrate access.
5. A malfunctioning RDU ™ tool.

Nexiq provides a Bendix application card for use with the
ProLink tool. It can also be used to diagnose the EC-
30 ™ , EC-17 ™ , Gen 4 ™ and Gen 5 ™ , and MC-30 ™ ABS
