Celica and MR2 models are equipped with a Supplemental Restraint System (SRS). When servicing vehicle, use care to avoid accidental air bag deployment. All SRS electrical connections and wiring harness(s) are covered with Yellow insulation. The Engine and Electronic Controlled Transmission (ECT) Electronic Control Unit (ECU) is used to control the engine fuel injection system and the transmission. In this article, control unit will be referred to as the ECU. ELECTRONIC CONTROL UNIT (ECU) The ECU receives information from various input devices and uses this information to control No. 1, No. 2 and lock-up solenoids. The ECU contains a self-diagnostic system, which will store fault code if failure or problem exists in the electronic control system. Fault code can be retrieved to determine transmission problem area. See SELF-DIAGNOSTIC SYSTEM. Coolant Temperature Sensor Signal Coolant temperature sensor delivers input signal to ECU, indicating engine coolant temperature. Coolant temperature sensor is located in coolant passage on the engine. SYSTEM DIAGNOSIS ECU monitors transmission operation and contains a self-diagnostic system which stores fault code if transmission electronic control system failure or problem exists. If system is operating correctly and no fault code exists, turn ignition off and remove jumper wire. Perform MANUAL SHIFTING TEST under TRANSMISSION SHIFT TESTING to determine if problem is a electrical or mechanical transmission problem. Check system by symptom. See appropriate symptom under SYMPTOM TROUBLESHOOTING. FAULT CODE List.
