3. Troubleshooting procedure 

Step Description 

Yes 

No 

1 

Will the troubleshooting procedure be 
implemented? 

To Step 2 

Troubleshooting 
procedure 

2 

Turn off the ignition switch and unfix the 
A/C compressor relay 
Turn on the ignition switch but do not 
start the engine and measure if the power 
source terminal on the relay socket has a 
voltage of 12V.  

To Step 4 

To Step 3 

3 

Check if the circuit between the 
compressor relay and the fuse suffers any 
of the following:  
•  Ground fault 

•  Open circuit 
•  Short circuit to the power source 

(anode) 

Confirm 
repair 

 

4 

Turn off the ignition switch, unfix the 
ECM fittings and check if the control 
circuit between the compressor relay and 
the ECM suffers any of the following:  
•  Ground fault 

•  Open circuit 

•  Short circuit to the power source 

(anode) 

Confirm 
repair 

To Step 5 

5 

Fix the compressor relay and ECM 
fittings. 

To Step 8 

To Step 6 

 

Turn on the ignition switch, directly 
ground Terminal 2 and see if A/C 
compressor relay still works.  

6 

Turn off the ignition switch and check if 
the control circuit between the 
electromagnetic clutch and the 
compressor relay suffers any of the 
following:  
•  Ground fault 

•  Open circuit 

•  Short circuit to the power source 

(anode) 

Confirm 
repair 

To Step 7 

7 

Replace A/C compressor relay. 
Confirm the replacement. 

 

 

8 

Replace engine control module (ECM) 
Confirm the replacement.
