Technical Service Bulletin • The customer may have one or more of the following concerns: • MIL is on. • Climate system heating performance is insufficient. • Coolant level warning is on. • Engine temperature is elevated. • “Limp Home” mode is active. • The results of the diagnosis based on the customer complaint may reveal one or more of the following: • One of the following faults may be stored in the transmission control module (address word 02): - 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. Climate system heating performance is insufficient due to coolant loss as a result of coolant migration in the electrical harness, faults in 08-Heating and Air Conditioning Electronics that result from coolant migration in the electrical harness, or a faulty N82 control valve. Technical Background Inspection of the coolant control valves N82, N509, or N488 reveals the presence of coolant inside the electrical connector as shown in the illustration (Figure 1). Figure 1.
