CUSTOMER COMPLAINT I

CHECK (A) : Check lock-up control signal from E.C.U.




1. Disconnect connector for water temperature sensor.
2. Connect resistor (2.0 kOhm) between terminals of water temperature sensor harness connector.
3. Start engine.




4. Check voltage between terminal (20) (+) and ground (-) when accelerator pedal is both depressed and not.




5. Stop engine.




6. Connect resistor (0.3 kOhm) between terminals of water temperature sensor harness connector.
7. Start engine.




8. Check voltage between terminal (20) (+) and ground (-) when both accelerator pedal is depressed and not.




Standard Voltage

CHECK (B) : Check ground circuit of E.C.U.




1. Turn ignition switch "OFF".
2. Disconnect 16-pin connector from E.C.U.
3. Check resistance between E.C.U. terminal (28), (36) and ground.

Standard resistance: Approx. 0 Ohm

CHECK (C) : Check lock-up solenoid from outside of A/T




1. Start engine.
2. Turn ignition switch "OFF".
3. Disconnect connector for A/T terminal.
4. Confirm that clinking sound is heard when power is applied.

CHECK (D) : Check lock-up solenoid
