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).
1. Fuse check:
Check the following fuses.
![HVAC System - Testing & Troubleshooting](images/books/1097/index 122(12).png)
Are the fuses OK?
YES
Go to step 2.
NO
Replace the fuse(s), and recheck. If the fuse(s) blows again, repair a short
in the No. B23 (30 A) and/or
No. B31 (7.5 A) fuse circuit(s).
2. A/C condenser fan low speed operation check:
- Jump the SCS line with the HDS.
NOTE: This step must be done to protect the PCM from damage.
- Disconnect the following connector.
PCM connector A (51P)
- Connect terminals A and B with a jumper wire.
![HVAC System - Testing & Troubleshooting](images/books/1097/index 123(13).png)
- Turn the vehicle to the ON mode.
Do the A/C condenser and radiator fans run on low?
YES
Go to step 3.
NO
Go to radiator and A/C condenser fan low speed circuit troubleshooting -
Refer to: A/C Condenser Fan
High Speed Circuit Troubleshooting, or Radiator and A/C Condenser Fan Low Speed
Circuit
Troubleshooting.
3. A/C condenser fan high speed operation check:
- Turn the vehicle to the OFF (LOCK) mode.
- Connect terminals A and B with jumper wires.
![HVAC System - Testing & Troubleshooting](images/books/1097/index 124(13).png)
- Turn the vehicle to the ON mode.
Does the A/C condenser fan (and radiator fan) run on high?
YES
Update the PCM if it does not have the latest software, or substitute a
known-good PCM, then
recheck.
NO
Go to step 4.
4. A/C condenser fan relay check:
- Turn the vehicle to the OFF (LOCK) mode.
- Disconnect the jumper wires.
- Remove the A/C condenser fan relay from the under-hood fuse/relay box,
and test it.
Is the relay OK?
YES
Go to step 5.
NO
Replace the A/C condenser fan relay.
5. Open wire check (+B SUB FAN line):
Measure the voltage between test points 1 and 2.
![HVAC System - Testing & Troubleshooting](images/books/1097/index 125(13).png)
![HVAC System - Testing & Troubleshooting](images/books/1097/index 126(13).png)
Is there battery voltage?
YES
The +B SUB FAN wire is OK. Go to step 6.
NO
An open in the +B SUB FAN wire. Replace the under-hood fuse/relay box.
6. Open wire check (IGP2 SUB line):
- Connect terminals A and B with jumper wire.
![HVAC System - Testing & Troubleshooting](images/books/1097/index 127(13).png)
- Turn the vehicle to the ON mode.
- Measure the voltage between test points 1 and 2.
![HVAC System - Testing & Troubleshooting](images/books/1097/index 128(13).png)
![HVAC System - Testing & Troubleshooting](images/books/1097/index 129(13).png)
Is there battery voltage?
YES
Repair an open in the wire between the under-hood fuse/relay box and the PCM.
NO
An open in the IGP2 SUB wire. Replace the under-hood fuse/relay box.
