Diagnostic Procedure

STEP	INSPECTION	RESULTS	ACTION
1	Does the A/C compressor disengage when the A/C switch is turned off?	Yes	Go to the next step.
1		No	Go to symptom troubleshooting “NO.24 A/C ALWAYS ON OR A/C COMPRESSOR RUNS CONTINUOUSLY”.
2	Perform the self-test function using the M-MDS. Turn the engine switch to the ON position (Engine off). Retrieve any DTCs. Are any DTCs displayed?	Yes	DTC is displayed: Go to the appropriate DTC test. (See DTC TABLE [WL-C, WE-C (Thailand, General (L.H.D. R.H.D.) specs.)].) Communication error message is displayed: Inspect the following: • Open circuit between main relay and PCM terminal 201, 203, 205 • Open circuit main relay and PCM terminal 219 • Main relay stuck open. • Open or poor ground circuit (PCM terminal 202, 204, 206) • Poor connection to vehicle body ground
2		No	No DTC is displayed: Inspect APP sensor. (See ACCELERATOR PEDAL POSITION (APP) SENSOR INSPECTION [WL-C, WE-C].)
3	Verify test results. • If normal, return to the diagnostic index to service any additional symptoms. (See SYMPTOM DIAGNOSTIC INDEX [WL-C, WE-C].) • If the malfunction remains, inspect the related Service Information and perform repair or diagnosis. ― If the vehicle is repaired, troubleshooting completed. ― If the vehicle is not repaired or additional diagnostic information is not available, reprogram the PCM if later calibration is available. Retest.
