DTC 86-71: F-CAN Communication With Yaw Rate-Lateral Acceleration Sensor Malfunction

WARNING: This page is about a different car, the 2011 Honda Fit, 2010 Honda Fit, and 2009 Honda Fit. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Before you troubleshoot, record all freeze data and any on-board snapshot, and review the general troubleshooting information. (See General Troubleshooting Information ).
NOTE: Troubleshoot the fuel and emissions DTCs first.
  1. Turn the ignition switch to ON (II).
  2. Clear the DTC with the HDS.
  3. Turn the ignition switch to LOCK (0) and then back to ON (II).
  4. Check for DTCs with the HDS.

    Is DTC 86-71 indicated? 

    YES  - If the DTC 86-01 is indicated at the same time, do the DTC 86-01 troubleshooting (see DTC 86-01: F-CAN BUS-OFF MALFUNCTION  ). If the DTC 86-01 is not indicated, go to step  5.

    NO  - If any other DTCs are indicated, go to the indicated DTCs troubleshooting. If DTCs are not indicated, intermittent failure, the system is OK at this time. Refer to intermittent failures troubleshooting (see Intermittent Failures  ).

  5. Turn the ignition switch to LOCK (0).
  6. Disconnect the yaw rate-lateral acceleration sensor 5P connector (see YAW RATE-LATERAL ACCELERATION SENSOR REPLACEMENT  ).
  7. Disconnect the VSA modulator-control unit 36P connector (see step  3 ).
  8. Check for continuity between the VSA modulator-control unit 36P connector terminal and the yaw rate-lateral acceleration sensor 5P connector terminal (see table below).

    Is there continuity? 

    YES  - Go to step  9.

    NO  - Repair open in the wire between the yaw rate-lateral acceleration sensor and the VSA modulator-control unit.

  9. Turn the ignition switch to ON (II).
  10. Measure the voltage between yaw rate-lateral acceleration sensor 5P connector terminal No. 1 and body ground.

    Is there battery voltage? 

    YES  - Go to step  11.

    NO  - Repair open in the wire between the No. 11 (7.5 A) fuse in the under-dash fuse/relay box and the yaw rate-lateral acceleration sensor.

  11. Turn the ignition switch to LOCK (0).
  12. Reconnect the yaw rate-lateral acceleration sensor 5P connector.
  13. Turn the ignition switch to ON (II).
  14. Measure the voltage between yaw rate-lateral acceleration sensor 5P connector terminal No. 5 and body ground.

    Is there 0.1 V or less? 

    YES  - Replace the yaw rate-lateral acceleration sensor (see YAW RATE-LATERAL ACCELERATION SENSOR REPLACEMENT  ).

    NO  - Repair open in the wire between the yaw rate-lateral acceleration sensor and body ground (G502).
