Honda HR-V: Paddle Shifter - (Downshift Switch) Circuit Troubleshooting (CVT)

SRS components are located in this area. Review the SRS component locations - Refer to: SRS Component Location Index (KA/KC), or SRS Component Location Index (KA/KC) and the precautions and procedures before doing repair or service.

1. Problem verification:

  1. Connect the HDS to the DLC - Refer to: How to Troubleshoot the Fuel and Emissions Systems, or How to Troubleshoot the CVT System (CVT).
  2. Turn the vehicle to the ON mode.
  3. Make sure the HDS communicates with the vehicle. If it does not, go to the DLC circuit troubleshooting.
  4. Check the parameter(s) below with the HDS when repeatedly pressing and releasing the paddle shifter - (downshift switch).

Continuously Variable Transmission (CVT) - Testing & Troubleshooting

Is ON indicated when you are pressing the paddle shifter - (downshift switch) and OFF with the switch released?

YES

Intermittent failure, the system is OK at this time.

NO

The failure is duplicated. Go to step 2.

2. Determine possible failure area (PCM, others):

  1. Turn the vehicle to the OFF (LOCK) mode.
  2. Jump the SCS line with the HDS.
  3. Disconnect the following connector.

PCM connector A (51P)

  1. Check for continuity between test points 1 and 2.

Continuously Variable Transmission (CVT) - Testing & Troubleshooting

Is there continuity when pressing the paddle shifter - (downshift switch) and no continuity when the paddle shifter - (downshift switch) is released?

YES

Update the PCM if it does not have the latest software, or substitute a known-good PCM, then recheck. If the symptom goes away and the PCM was updated, troubleshooting is complete. If the symptom goes away and the PCM was substituted, replace the original PCM.

NO

Go to step 3.

3. Determine possible failure area (paddle shifter - (downshift switch), others):

  1. Remove the steering wheel.
  2. Check for continuity between test points 1 and 2.

Is there continuity when pressing the paddle shifter - (downshift switch) and no continuity when the paddle shifter - (downshift switch) is released?

YES

Go to step 5.

NO

Go to step 4.

4. Paddle shifter - (downshift switch) operation check:

  1. Disconnect the following connector

Paddle shifter - (downshift switch) 2P connector

  1. Check for continuity between test points 1 and 2.

Continuously Variable Transmission (CVT) - Testing & Troubleshooting

Is there continuity when pressing the paddle shifter - (downshift switch) and no continuity when the paddle shifter - (downshift switch) is released?

YES

The paddle shifter - (downshift switch) is OK. Replace the cable reel subharness.

NO

Replace the paddle shifter - (downshift switch).

5. Open wire check (GND line):

  1. Remove the cable reel.
  2. Check for continuity between test points 1 and 2.

Continuously Variable Transmission (CVT) - Testing & Troubleshooting

Is there continuity?

YES

The GND wire is OK. Go to step 6.

NO

Repair an open in the GND wire between the cable reel and ground (G401), or repair poor ground (G401).

6. Shorted wire check (PADDLE SW DOWN line):

Check for continuity between test points 1 and 2.

Is there continuity?

YES

Repair a short to ground in the PADDLE SW DOWN wire between the cable reel and the PCM.

NO

The PADDLE SW DOWN wire is not shorted. Go to step 7.

7. Open wire check (PADDLE SW DOWN line):

  1. Connect terminals A and B with a jumper wire.

Is there continuity?

YES

The PADDLE SW DOWN wire is OK. Replace the cable reel.

NO

Repair an open in the PADDLE SW DOWN wire between the cable reel and the PCM.
