Service bulletin 68166105A

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Part Description: ATX Shifter Issue Description: Prior to removing (or disconnecting) the automatic transmission shifter knob, for any service to the shifter or for console removal, disconnect and isolate the battery negative cable. Wait two minutes for the system capacitor to discharge before further service. This will prevent a P1C86-14 DTC being stored in the electronic shift module (ESM). Failure to disconnect the battery before servicing the shifter may cause the P1C86-14 DTC to be set again. Clear the code before replacing the shifter. In the event a P1C86-14 DTC persist after following the above procedure, refer to 28 - DTC-Based Diagnostics, in the service manual.
