Honda HR-V: Testing

CRUISE CONTROL (ECM/PCM) INPUT TEST

NOTE: Always make sure that you have the latest HDS software.

1. Turn the vehicle to the OFF (LOCK) mode

2. Connect the HDS (Honda Diagnostic System) to the data link connector (DLC) (A) located under the driver's side of the dashboard.

3. Turn the vehicle to the ON mode.

4. Make sure the HDS communicates with the PCM and other vehicle systems. If it does not, go to the DLC circuit troubleshooting.

5. Select PGM-FI system and check the diagnostic trouble code (DTC) in the DTC MENU on the screen and note it. Also check the freeze data and/or onboard snapshot data, and download any data found. Then refer to the indicated DTC's troubleshooting, and begin the appropriate troubleshooting procedure.

6. If no DTCs are found, do the following tests while monitoring parameters in the DATA LIST with the HDS.

7. If the input tests prove OK, replace the PCM.

NOTE: Intermittent failures are often caused by loose circuit connections. While monitoring cruise control inputs, flex the circuit wires, and note if any of the test results change.
