NOTE:
- Before you troubleshoot, review the general troubleshooting information.
- Refer to the DTC code shown on the display, and then inspect the connectors and terminals based on the instructions in the table below.
- The DTC may be stored due to loss of voltage supply or ground at the transmitting control unit. Verify voltage supply and ground are OK on the control unit related to the specific code before following this troubleshooting.

DTCs (VSA)
- Problem verification
-1. Turn the vehicle to the ON mode.
-2. Clear the DTC with the HDS.
-3. Turn the vehicle to the OFF (LOCK) mode, then to the ON mode.
-4. Check for DTCs with the HDS.

YES
Go to step 2.
NO
Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the transmitting control units, and VSA modulator-control unit. Refer to intermittent failures troubleshooting . If the freeze data/on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the Freeze data/on-board snapshot.
- Open wire check (F-CAN_H, F-CAN_L lines)
-1. Turn the vehicle to the OFF (LOCK) mode.
-2. Disconnect the receiving control unit connector.
VSA modulator-control unit 21P connector
-3. Disconnect the transmitting control unit connectors.(Refer to the DTC code shown on the display, and then disconnect the connector(s) based on the instructions in the table below.)
NOTE: Always short the SCS line with the HDS before removing PCM connector(s).
PCM connector A (51P) Gauge control module 32P connector AWD control unit 24P connector Steering angle sensor 4P connector Electric parking brake control unit 30P connector SRS unit connector A (39P) -4. Check for continuity between the receiving control unit and the transmitting control unit on the F-CAN_H circuit and the F-CAN_L circuit as specified in the table while in the vehicle OFF (LOCK) mode.
Test condition Vehicle OFF (LOCK) mode DTC CIRCUIT NAME RECEIVING CONTROL UNIT TRANSMITTING CONTROL UNIT Is there continuity?
YES
The F-CAN_H and F-CAN_L wires are OK. Go to step 3.
NO
Repair an open in the F-CAN_H and/or F-CAN_L wires between the receiving control unit and the transmitting control unit.
- Determine possible failure area (the receiving control unit or the transmitting control unit)
-1. Reconnect all connectors.
-2. Turn the vehicle to the ON mode.
-3. Clear the DTC with the HDS.
-4. Turn the vehicle to the OFF (LOCK) mode, then to the ON mode.
-5. Check for DTCs with the HDS.

YES
Check for loose terminals and poor connections in the VSA modulator-control unit 21P connector. If the VSA modulator-control unit was updated and the symptom/indication is still present, replace the VSA modulator-control unit .
NO
The VSA modulator-control unit is OK at this time, replace the transmitting control unit.(Refer to the DTC code shown on the display, and then replace the control unit based on the instructions in the table below.)
