DTC U0131 : Gauge control module lost communication with EPS unit
DTC U0151 : Gauge control module lost communication with SRS unit
DTC U1100 : Gauge control module lost communication with Driving Support System Control Unit
NOTE:
- 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 the grounding failure or the power source failure at the transmitting control unit (the grounding inspection and the power source inspection on each control unit are required prior to this checking process).

DTC (Gauge Control Module)
NOTE:
- If you are troubleshooting multiple DTCs, be sure to follow the instructions in B-CAN System Diagnosis Test Mode A .
- If you have any loss of communication DTCs for the PCM, troubleshoot those DTCs first.
- Problem verification
-1. Clear the DTCs with the HDS.
Clear DTCs
-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.

YES
Go to step 2.
NO
Intermittent failure, the system is OK at this time. Check for loose or poor connections.
- Open wire check (F-CAN_L, F-CAN_H lines)
-1. Turn the vehicle to the OFF (LOCK) mode.
-2. Jump the SCS line with the HDS, and wait more than 1 minute.
SCS short
-3. Disconnect the receiving control unit connector.
Gauge control module 32P connector -4. 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.)
PCM connector A (51P) Multipurpose camera unit 20P connector i-VTM control unit 24P connector VSA modulator-control unit 38P connector Keyless access/TPMS control unit connector C (20P) EPS control unit connector B (8P) SRS unit connector A (39P) -5. 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 mode.
DTC CIRCUIT NAME RECEIVING CONTROL UNIT TRANSMITTING CONTROL UNIT U0151 F-CAN_H Gauge control module 32P connector No. 24 SRS unit connector A (39P) No. 34 F-CAN_L Gauge control module 32P connector No. 25 SRS unit connector A (39P) No. 35 U1100 F-CAN_H Gauge control module 32P connector No. 24 Multipurpose camera unit 20P connector No. 2 F-CAN_L Gauge control module 32P connector No. 25 Multipurpose camera unit 20P connector No. 13 Is there continuity?
YES
The F-CAN_L to F-CAN_H wires are OK. Go to step 3.
NO
Repair an open in the wire(s).
- 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 DTCs with the HDS.
Clear DTCs
-4. Turn the vehicle to the OFF (LOCK) mode and then the ON mode.
-5. Wait for at least 6 seconds.
-6. Check for DTCs with the HDS.
