A/C Condenser Fan High Speed Circuit Troubleshooting

NOTE:

- Do not use this troubleshooting procedure if the A/C compressor is inoperative. Refer to the symptom troubleshooting index.
- Before doing any symptom troubleshooting, check for powertrain DTCs, R20A3 engine model, K24Z3 engine model.

1. Check the No. 5 (20 A) and No. 21 (7.5 A) in the under-hood fuse/relay box.

Are the fuses OK?

YES | - | Go to Step 2 .
NO | - | Replace the fuse(s), and recheck. If fuse(s) blow again, check for a short in the No. 5 (20 A) fuse and No. 21 (7.5 A) fuse circuits.■

1. Jump the SCS line with the HDS.
   NOTE: This step must be done to protect the engine/powertrain control module (ECM/PCM) from damage.

1. Disconnect ECM/PCM connector A (44P) (R20A3 engine model) or ECM/PCM connector A (49P) (K24Z3 engine model).

1. Turn the ignition switch to ON (II).

1. Measure the voltage between the ECM/PCM connector A (44P) No. 5 terminal (R20A3 engine model) or ECM/PCM connector A (49P) No. 6 terminal (K24Z3 engine model) and body ground.

Is there battery voltage?

YES | - | Go to Step 6 .
NO | - | Repair open in the wire between the under-hood fuse/relay box and the ECM/PCM. If the wire is OK, replace the under-hood fuse/relay box. ■

1. Turn the ignition switch to LOCK (0).
