- Problem verification
- 1. Clear the DTCs with the HDS.
- 2. Turn the vehicle to the OFF (LOCK) mode and then the ON mode.
- 3. Wait for at least 6 seconds.
- 4. Check for DTCs with the HDS.

Go to the troubleshooting for CAN gateway system DTC (s) .
NO
Go to step 3.
- F-CAN circuit communication check
- 1. Select the FUNCTION TEST in the CAN gateway with the HDS, then select the F-CAN Bus Connected Unit Check.
F-CAN Bus Connected Unit Check
Which result is indicated?
SH-AWD CONTROL UNIT (Bus A) is Not Available
Go to step 4.
GAUGE CONTROL MODULE (Bus A) is Not Available
Go to step 6.
SH-AWD CONTROL UNIT and GAUGE CONTROL MODULE are Detected
Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the gauge control module, the CAN gateway, and the SH-AWD control unit.
- Open wire check (F-CAN A_H line)
- 1. Turn the vehicle to the OFF (LOCK) mode.
- 2. Disconnect the following connectors.
CAN gateway 24P connector SH-AWD control unit 24P connector - 3. Check for continuity between test points 1 and 2.
Test condition Vehicle OFF (LOCK) mode CAN gateway 24P connector: disconnected SH-AWD control unit 24P connector: disconnected Test point 1 CAN gateway 24P connector No. 14 Test point 2 SH-AWD control unit 24P connector No. 14 - Refer to:
SH-AWD ® Control Unit Connector for Inputs and Outputs (2016) or
SH-AWD ® Control Unit Connector for Inputs and Outputs (2017 2018 2019 2020)Is there continuity?
YES
The F-CAN A_H wire is OK. Go to step 5.
NO
Repair an open in the F-CAN A_H wire between the SH-AWD control unit and the CAN gateway.
- Open wire check (F-CAN A_L line)
- 1. Check for continuity between test points 1 and 2.
Test condition Vehicle OFF (LOCK) mode CAN gateway 24P connector: disconnected SH-AWD control unit 24P connector: disconnected Test point 1 CAN gateway 24P connector No. 15 Test point 2 SH-AWD control unit 24P connector No. 24 - Refer to:
SH-AWD ® Control Unit Connector for Inputs and Outputs (2016) or
SH-AWD ® Control Unit Connector for Inputs and Outputs (2017 2018 2019 2020)Is there continuity?
YES
The F-CAN A_L wire is OK. Check for poor connections or loose terminals at the CAN gateway and the SH-AWD control unit. Update the SH-AWD control unit - Refer to: SH-AWD ® Control Unit Update (2016 2017 2018 2019 2020) if it does not have the latest software, or substitute a known-good SH-AWD control unit - Refer to: SH-AWD ® Control Unit Removal and Installation (SH-AWD) (2016 2017 2018 2019 2020) , then recheck. If DTC U0114 goes away and the SH-AWD control unit was updated, troubleshooting is complete. If DTC U0114 goes away and the SH-AWD control unit was substituted, replace the original SH-AWD control unit - Refer to: SH-AWD ® Control Unit Removal and Installation (SH-AWD) (2016 2017 2018 2019 2020) .
NO
Repair an open in the F-CAN A_L wire between the SH-AWD control unit and the CAN gateway.
- Open wire check (F-CAN A_H line)
- 1. Turn the vehicle to the OFF (LOCK) mode.
- 2. Disconnect the following connectors.
