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 J1939 link at the in‑cab off‑board

diagnostic connector (9‑Pin).

2. The ECU does not support PID194.

3. No power is being supplied to the ECU and/or the

diagnostic connector.

4. The J1939 bus is overloaded with information and the

RDU can not arbitrate access.

5. A malfunctioning RDU tool.
