| A801304 2033806- | 2017-12-05. Service bulletin. Supersedes Technical Service Bulletin Group 80 number 13-03 dated May 13, 2013. Malfunction Indicator Lamp is on. Climate system heating performance is insufficient. Coolant level warning is on. Engine temperature is elevated. "Limp Home" mode is active. Faults are stored in the transmission control module. 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. Climate system heating performance is insufficient due to coolant loss, or due to a faulty N82 control valve. Inspection of the coolant control valves N82, N509, or N488 reveals the presence of coolant inside the electrical connector. The connectors, wiring harness, and/or connected control units may have been damaged from exposure to coolant. |
| A941323 2033675- | 2017-12-05. Service bulletin. Supersedes Technical Service Bulletin Group 94 number 13-17 dated May 22, 2013. DTC 03073 (Closed Rear Lid Sensor - Incorrect Signal) may be stored in the comfort system central control module, J393 (address word 46). In order for the vehicle to receive a proper rear lid status signal when the lid is operated, the paddle switches on the rear sill trim must contact the opposing lid latch points uniformly. When the rear lid is opened, the paddle switches change state and the comfort system central control module 2, J773, will read G525 and G526. It will then communicate to the comfort system central control module, J393. |
