IPC won't program
This car came in running and driving but because the programmer's tool couldn't communicate the car was brought to me. I have another thread under “Communication”. Only 1 module on the hsgmlan communicated with the scanner and that was the EBCM. Incidentally the EBCM also communicates on Chassis hsgmlan. Found out that pin 6 and 14 on the dlc had the Chassis Bus and 12 and 13 had the hsgmlan. Communication from all modules on hsgmlan returned after swapping wires. Now a different Programing tech flashed the IPC 4 times in front of me but the cluster still displays "program cluster".
According to the owner, he had required the dealership where he bought it from to program the mileage before sending the cluster to him. This cluster is displaying fault message for systems that don't exist in this vehicle like rear differential and suspension system , plus the mileage is still in metric. Is the cluster shot from the dealer programming it?
Not sure if this helps but I put a reman cluster from gm into a Sierra and then drove it to the dealer for programming. Could not do it as it had accumulated mileage and therefore SPS thought it was used. Had to but another cluster and start over again.
If it was a used cluster yes or is gone since you can't reprogram a used cluster on global A protocol.
It needs setup. Use SPS2 and choose setup instead of programming. it’s programmed. Until you finish the job it’s going to say that though
Hi Lesage, The IPC rebuilder won't be able to program miles as that's stored in the BCM. See …Q, Document ID: 5608004 The correct procedure is, P16 Instrument Cluster: Programming and Setup: Using Techline Connect - Document ID: 2552107 - On the SPS Supported Controllers screen, select Instrument Cluster – Programming and follow the on-screen instructions. - On the SPS…
Yea I told the owner (used car dealer) that the odo info comes from the BCM so I don' t know how the dealer might have done that without engineering tools.
Thanks Allan for the answer. I'll pass it on to the programming tech. We'll see what happens.
