Diagnosis - 4-Speed: Description

Automatic transaxle is electronically controlled by a Transmission Control Module (TCM). The TCM controls shift points, engine braking, lock-up torque converter operation and other various operations. The TCM receives information from various input devices and uses this information to operate duty and shift control solenoid valves. Depending on throttle position, the TCM controls shift points, lock-up torque converter operation and overdrive. An electronically controlled full-time AWD system is available. This system has a transfer hydraulic pressure control unit incorporating duty solenoid and multi-plate transfer type clutch on rear of transmission.

Vehicle also utilizes AT OIL TEMP light to indicate trouble codes. The TCM incorporates a self-diagnosis ability to detect electronic system or component malfunctions. On all models, transaxle is equipped with shift and key interlock systems. Shift interlock system prevents shift selector lever from being moved from Park unless brake pedal is depressed and accelerator is in idle position. In case of a malfunction, shift selector lever can be released by depressing button on front of shifter console. Key interlock system prevents ignition key from being removed from ignition lock assembly unless shift selector lever is in Park position.
