A/C Signal Circuit Troubleshooting

1. Measure the voltage between the driver's under-dash fuse/relay box connector F (33P) No. 5 terminal and body ground.

Is there battery voltage?

YES | - | Repair open in the wire between the A/C compressor and the MICU.■
NO | - | Check for loose wire or poor connections at driver's under-dash fuse/relay box connector F (33P) No. 5 terminal. If the connections are good, substitute a known-good MICU and recheck. If the symptom goes away, replace the original MICU .■
