TCM Self-Diagnostic Procedure (No Tools)

TCM SELF-DIAGNOSTIC PROCEDURE (NO TOOLS)

Description
As a method for locating the suspect circuit, when the self-diagnostics start signal is input, the memory for the malfunction location is output and the A/T CHECK indicator lamp flashes to display the corresponding DTC.

Diagnostic Procedure
1. CHECK A/T CHECK INDICATOR LAMP





1. Start the engine with selector lever in "P" position. Warm engine to normal operating temperature.
2. Turn ignition switch ON and OFF at least twice, then leave it in the OFF position.
3. Wait 10 seconds.
4. Turn ignition switch ON. (Do not start engine.)
Does A/T CHECK indicator lamp come on for about 2 seconds?
YES >> GO TO 2.
NO >> Go to AT-191, "A/T Check Indicator Lamp Does Not Come On". A/T Check Indicator Lamp Does Not Come On

2. JUDGEMENT PROCEDURE STEP 1
1. Turn ignition switch OFF.





2. Push shift lock release button.





3. Move selector lever from "P" to "D" position.
4. Release accelerator pedal. (Set the closed throttle position signal ON.)





5. Depress brake pedal. (Stop lamp switch signal ON.)
6. Turn ignition switch ON. (Do not start engine.)
7. Wait 3 seconds.
