Recovery Process from a Controller Reprogramming Interruption
During service reprogramming of the T87 TCM, some technicians may notice the TCM may fail during the
reprogramming event and become unresponsive to the Service Programming System (SPS), unresponsive
to the GDS2 tool. This bulletin addresses corrective actions to attempt to recover the module before
declaring the TCM as a bad part and replacing.
During reprogramming, an interruption can cause the module to lock up. A module reset may recover the
TCM
