What kind of problem are you having? Please give me all the details.

Thanks, Ron

Customer: replied 10 months ago.

2004 Mazda RX-8 with six speed manual with the following codes:

PCM: CODE U0121

INSTRUMENT CLUSTER: CODE U1900

ABS MODULE: CODE U1900

I've checked all the wiring and connectors at the ABS module, PCM and Instrument Cluster and already replaced the ABS module and PCM from a friend's good working condition RX-8 but the codes are still the same.

I would like to know where to look specifically for this problem and would appreciate an illustration on the Specific CAN WIRES to check for the connectivity issue?

thanks!

Hello. The U0121 leads into the U1900. I can email all the diagnostic information to you if you would like in a PDF file for 5.00. It is a 44 step diagnostic flow chart. If you find yourself needing additional diagrams or anything else you can email me back and I'll get them to you as well. Let me know. Thanks.
