DTC 41-5

DTC 41-5: F-CAN Malfunction (Lost Communication with Yaw Rate-Lateral Acceleration Sensor)

NOTE: Before you troubleshoot, review the general troubleshooting information.

1. Turn the ignition switch to ON (II).
2. Make sure the HDS communicates with the vehicle and the SH-AWD control unit. If it doesn't, troubleshoot the DLC circuit.
3. Check for DTCs in the VSA system with the HDS.

Are any yaw rate-lateral acceleration sensor DTCs or F-CAN indicated?

YES - Go to the indicated DTC's troubleshooting.

NO - Go to step 4.

4. Clear the DTC with the HDS.
5. Start the engine.
6. Check for DTCs with the HDS.

Is DTC 41-5 indicated?

YES - Go to step 7.

NO - Intermittent failure, the system is OK at this time. Check for intermittent open between SH-AWD control unit connector terminals A10 and A20 and yaw rate-lateral acceleration sensor 4P connector terminals No. 2 and No. 3.

7. Turn the ignition switch to LOCK (0).
8. Jump the SCS line with the HDS.

NOTE: This step must be done to prevent PCM damage.

9. Disconnect the yaw rate-lateral acceleration sensor 4P connector.
10. Connect yaw rate-lateral acceleration sensor 4P connector terminals No. 3 and No. 2 to body. ground with jumper wires.





11. Disconnect SH-AWD control unit connector A (20P).
12. Check for continuity between SH-AWD control unit connector terminals A10 and A20 to body ground.





Is there continuity?

YES - Update the SH-AWD control unit if it does not have the latest software, or substitute a known-good SH-AWD control unit and recheck. If the symptom/indication goes away with the updated SH-AWD control unit, troubleshooting is complete. If the symptom/indication goes away with a known-good SH-AWD control unit, replace the original SH-AWD control unit.

NO - Repair open in the wires between the SH-AWD control unit and the yaw rate-lateral acceleration sensor.
