- Open wire check (F-CAN_L, F-CAN_H lines)
- 1. Turn the vehicle to the OFF (LOCK) mode.
- 2. Disconnect the following connectors.
VSA modulator-control unit 38P connector Steering angle sensor 4P connector - 3. Check for continuity between test points 1 and 2.
Test condition Vehicle OFF (LOCK) mode VSA modulator-control unit 38P connector: disconnected Steering angle sensor 4P connector: disconnected Test circuit F-CAN_L Test point 1 VSA modulator-control unit 38P connector No. 26 (BLK) Test point 2 Steering angle sensor 4P connector No. 3 (BLK) Test circuit F-CAN_H Test point 1 VSA modulator-control unit 38P connector No. 38 (WHT) Test point 2 Steering angle sensor 4P connector No. 2 (WHT) Is there continuity?
YES
The F-CAN_L and F-CAN_H wires are OK. Go to step 3.
NO
Repair an open in the wire between the steering angle sensor and the VSA modulator-control unit.
- Open wire check (IG1 SAFETY line)
- 1. Turn the vehicle to the ON mode.
- 2. Measure the voltage between test points 1 and 2.
Test condition Vehicle ON mode VSA modulator-control unit 38P connector: disconnected Steering angle sensor 4P connector: disconnected Test circuit IG1 SAFETY Test point 1 Steering angle sensor 4P connector No. 1 (YEL) Test point 2 Body ground Is there battery voltage?
YES
The IG1 SAFETY wire is OK. Go to step 4.
NO
Repair an open in the wire between the No. D23 (7. 5 A) fuse in the driver's under-dash fuse/relay box and the steering angle sensor.
- Open wire check (SGND line)
- 1. Turn the vehicle to the OFF (LOCK) mode.
- 2. Reconnect the following connectors.
VSA modulator-control unit 38P connector Steering angle sensor 4P connector - 3. Turn the vehicle to the ON mode.
- 4. Measure the voltage between test points 1 and 2.
Test condition Vehicle ON mode Test circuit SGND Test point 1 Steering angle sensor 4P connector No. 4 (BRN) Test point 2 Body ground Is there 0. 1 V or less?
YES
The SGND wire is OK. Go to step 5.
NO
Repair an open in the wire between the steering angle sensor and body ground (G507).
- Steering angle sensor check (substitution)
- 1. Turn the vehicle to the OFF (LOCK) mode.
- 2. Substitute a known-good steering angle sensor.
- 3. Turn the vehicle to the ON mode.
- 4. Clear the DTC with the HDS.
- 5. Turn the vehicle to the OFF (LOCK) mode, then to the ON mode.
- 6. Check for DTCs with the HDS.
DTC Description DTC Freeze Frame 86-19 F-CAN Communication With Steering Angle Sensor Malfunction Is DTC 86-19 indicated?
YES
Go to step 6.
NO
- VSA modulator-control unit check (update)
- 1. Update the VSA modulator-control unit if it does not have the latest software.
- 2. Turn the vehicle to the OFF (LOCK) mode, then to the ON mode.
- 3. Check for DTCs with the HDS.
DTC Description DTC Freeze Frame Is DTC 86-19 indicated?
YES
Check for loose terminals in the VSA modulator-control unit 38P connector. If the VSA modulator-control unit was updated and the symptom/indication is still present, replace the VSA modulator-control unit .
NO
Troubleshooting is complete. If any other DTCs are indicated, go to the indicated DTCs troubleshooting.
