Technical Service Bulletin MIL on. Climate system heating performance is insufficient. Coolant level warning is on. Engine temperature is elevated. “Limp Home” mode is active. Workshop findings: The results of the diagnosis based on the customer concern may reveal one or more of the following: One of the following faults may be stored in the transmission control module (TCM), J217 (address word 0002): DTC P275300 (Transmission Fluid Cooler Control Circuit Open) DTC P275500 (Transmission Fluid Cooler Control Circuit High) Coolant loss is found from one or more control valves: N82, N509, or N488. Coolant may have migrated into the wiring harness through the connector and into various control units.
