Honda HR-V: 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 - Refer to: Heating and A/C Systems Symptom
Troubleshooting Index
(Heating/Air Conditioning), or Climate Control System Symptom
Troubleshooting Index (Climate
Control).
- If the A/C system is inoperable, the radiator and A/C condenser fans are
controlled based only on engine
coolant temperature.
- Before doing symptom troubleshooting, check for PGM-FI DTCs - Refer to:
How to Troubleshoot the
Fuel and Emissions Systems, or How to Troubleshoot the CVT System (CVT).
