Honda HR-V: A/C Signal Circuit Troubleshooting
1. A/C compressor clutch condition check.
- Start the engine, and let it idle.
- Turn the blower switch on.
- Turn the A/C switch on.
- Check the parameter(s) below with the HDS.
Do the current condition(s) match the threshold?
YES
Go to step 2.
NO
Do the A/C system test.
2. A/C system check.
- Check the A/C system.
Does the A/C system operate?
YES
The A/C system circuit is OK.
NO
Go to step 3.
3. A/C compressor clutch circuit check.
- Turn the vehicle to the OFF (LOCK) mode.
- Turn the vehicle to the ON mode.
- Activate the A/C CLUTCH in the INSPECTION MENU with the HDS.
A/C CLUTCH
Is there a clicking noise from the A/C compressor clutch?
YES
The A/C compressor clutch circuit is OK. Do the A/C system test.
NO
Go to step 4.
4. Open wire check (A/C MG CLUTCH RLY CL- line).
- Turn the vehicle to the OFF (LOCK) mode.
- Jump the SCS line with the HDS.
SCS Short
- Disconnect the following connector.
PCM connector A (51P)
- Turn the vehicle to the ON mode.
- Connect terminals A and B with a jumper wire.
Is there a clicking noise from the A/C compressor clutch?
YES
The A/C MG CLUTCH RLY CL- wire is OK. Update the PCM if it does not have the
latest software, or substitute a known-good PCM, then recheck. If the
symptom/indication goes away and the PCM was updated, troubleshooting is
complete. If the symptom/indication goes away and the PCM was substituted,
replace the original PCM.
NO
Check for poor connections or loose terminals at the A/C compressor clutch
relay and the PCM. If the
connections and terminals are OK, check the A/C compressor clutch relay. If
needed, repair an open in
the A/C MG CLUTCH RLY CL- wire between the PCM (A12) and the A/C compressor
clutch relay, or
other parts in the A/C systems.
