Official summary
This Preliminary information communicates to the dealer if a vehicle comes in for an MIL or a message with DTC U1345 Engine Control Module LIN Bus 1 (or Bus 21) and/or DTC U135A that engineering is working on the issue and to clear the codes and return to the customer, Mil and message still may be one but at that time will drive normally for the next 100 ignition cycles.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
