STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA HAS BEEN RECORDED Has FREEZE FRAME DATA been recorded?	Yes	Go to the next step.
1		No	Record FREEZE FRAME DATA on the repair order, then go to the next step.
2	VERIFY RELATED REPAIR INFORMATION AVAILABILITY Verify related Service Bulletins and/or on-line repair information availability. Is any related Service Bulletins available?	Yes	Perform repair or diagnosis according to the available Service Bulletins. If the vehicle is not repaired, go to the next step.
2		No	Go to the next step.
3	INSPECT REFRIGERANT PRESSURE SENSOR CONNECTOR FOR POOR CONNECTION Switch the ignition to off Disconnect the refrigerant pressure sensor connector. Inspect for poor connection (such as damaged/pulled-out pins, corrosion). Are there any malfunction?	Yes	Repair or replace suspected part, then go to Step 9.
3		No	Go to the next step
4	INSPECT REFRIGERANT PRESSURE SENSOR SIGNAL CIRCUIT FOR SHORT TO GROUND Switch the ignition to off Inspect for continuity between refrigerant pressure sensor terminal D (wiring harness-side) and body ground. Is there continuity?	Yes	Repair or replace suspected part, then go to Step 9.
4		No	Go to the next step
5	INSPECT PCM CONNECTOR FOR POOR CONNECTION Switch the ignition to off. Disconnect the PCM connector Inspect for poor connection (such as damaged/pulled-out pins, corrosion) Are there any malfunction?	Yes	Repair or replace suspected part, then go to Step 9.
5		No	Go to the next step.
6	INSPECT REFRIGERANT PRESSURE SENSOR CIRCUIT FOR OPEN CIRCUIT Inspect for continuity between refrigerant pressure sensor terminal D (wiring harness-side) and PCM terminal 1M (wiring harness-side) Is there continuity?	Yes	Go to the next step
6		No	Repair or replace suspected part, then go to Step 9.
7	INSPECT REFRIGERANT PRESSURE SENSOR POWER CIRCUIT FOR OPEN CIRCUIT Switch the ignition to off Verify the continuity between refrigerant pressure sensor terminal A (wiring harness-side) and PCM terminal 1BJ (wiring harness-side). Is there continuity?	Yes	Go to the next step.
7		No	Repair or replace suspected part, then go to Step 9.
8	INSPECT REFRIGERANT PRESSURE SENSOR Inspect the refrigerant pressure sensor. (See REFRIGERANT PRESSURE SENSOR INSPECTION [FULL-AUTO AIR CONDITIONER] .) (See REFRIGERANT PRESSURE SENSOR INSPECTION [MANUAL AIR CONDITIONER] .) Is there any malfunction?	Yes	Replace the refrigerant pressure sensor, then go to the next step
8		No	Go to the next step
9	VERIFY TROUBLESHOOTING OF DTC P0532:00 HAS BEEN COMPLETED Make sure to reconnect all disconnected connectors Clear the DTC from the PCM memory using the M-MDS. Start the engine and warm it up completely Turn the A/C switch and the fan switch on. Retrieve DTCs using the M-MDS. Is the PENDING CODE for this DTC present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [MZI-3.7] .)
9		No	Go to the next step
10	VERIFY AFTER REPAIR PROCEDURE Perform the "AFTER REPAIR PROCEDURE" (See AFTER REPAIR PROCEDURE [MZI-3.7] .) Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [MZI-3.7] .)
10		No	Troubleshooting completed
