Alert me when someone posts in this thread:

Greetings,

It's not easy to diagnose from the get go however, step by step it can be narrowed down.

I have to dig down further, but initially looking at the SPA sys in WIS, Reverse Gear On/OFF from TCM sends information to DICE module to set SPA in status mode Active.
Further in WIS... TCM on P-BUS sends a message through MIU on I-BUS to DICE that it is in R gear, reversing light switch is on and SPA status mode becomes Active.
TCM (P-BUS) >> MIU(GATEWAY) >> DICE (I-BUS) >> SPA
When it happens and SPA becomes active, I would look at live data from TCM via Tech2 to see if DICE is receiving ON from TCM (reversing-light switch)and if at all gear selection changes to R and reverse lights at the back come on. I would then look and troubleshoot reversing-light switch 31 on the transmission.
Then with IGN off I would look at SPA module 630 in the trunk (Switch A) 5 pin connector and with multimeter ring WH wire pin 4 and GN wire pin 5 all the way to DICE module moving wire harness at several spots along the way.
There is a list of troubleshooting tests you can perform by using WIS and various wiring diagrams.
I hope my initial information helps.
Cheers,
