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 - Refer to:



Body Electrical Troubleshooting - B-CAN System Diagnosis Test Mode A - Initial Communication and DTC Checks (2017 2018 2019 2020)
  1. 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 4 seconds.

    - 4. Check for DTCs with the HDS.

    DTC Description DTC
    B1192 Gauge control module lost communication with Battery sensor ECU (LIN bus connected)  
    B1193 Gauge control module lost communication with Steering Switch (LIN bus connected)  
    B1196 Gauge control module lost communication with Battery Blower (LIN bus connected)  

    Is DTC B1192 indicated?

    YES: B1192 indicated

    Go to step 2.

    YES: B1192, B1193, and B1196 indicated

    Go to step 5.

    NO 

    Intermittent failure, the system is OK at this time. Check for loose or poor connections.

  2. Fuse check

    - 1. Check the following fuse.

    Fuse No. B10 (7.5 A)
    Location Main under-hood fuse box

    Is the fuse OK?

    YES 

    Go to step 3.

    NO 

    Replace the fuse. If the fuse blows again, repair a short to ground in the No. B10 (7.5 A) fuse circuit.

  3. Open wire check (+B BMS line)

    - 1. Turn the vehicle to the OFF (LOCK) mode.

    - 2. Disconnect the following connector.

    Battery sensor 2P connector

    - 3. Measure the voltage between test points 1 and 2.

    Test condition Vehicle OFF (LOCK) mode
    Battery sensor 2P connector: disconnected
       
    Test point 1 Battery sensor 2P connector (female terminals) No. 1:
    Test point 2 Body ground

    Is there battery voltage?

    YES 

    The +B BMS wire is OK. Go to step 4.

    NO 

    Repair an open or high resistance in the wire.

  4. Open wire check (LIN (METER) line)

    - 1. Disconnect the following connector.

    Gauge control module connector A (32P)

    - 2. Check for continuity between test points 1 and 2.

    Test condition Vehicle OFF (LOCK) mode
    Gauge control module connector A (32P): disconnected
    Battery sensor 2P connector: disconnected
       
    Test point 1 Battery sensor 2P connector (female terminals) No. 2:
    Test point 2 Gauge control module connector A (32P) (female terminals) No. 24 - Refer to:
    Gauge Control Module Input Test (2017 2018 2019 2020)

    Is there continuity?

    YES 

    Replace the battery sensor - Refer to: 12 Volt Battery Sensor Removal and Installation (2016 2017 2018 2019 2020),

    NO 

    An open or poor connection in the LIN (METER) wire between the gauge control module and the battery sensor.

  5. Shorted wire check (LIN (METER) line)

    - 1. Turn the vehicle to the OFF (LOCK) mode.

    - 2. Disconnect the following connectors.

    Battery sensor 2P connector
    Gauge control module connector A (32P)
    Without navigation: Audio remote-HFL switch 16P connector
    With navigation: Audio remote/HFL-navigation voice control switch 16P connector

    - 3. Check for continuity between test points 1 and 2.

    Test condition Vehicle OFF (LOCK) mode
    Battery sensor 2P connector: disconnected
    Gauge control module connector A (32P): disconnected
    Without navigation: Audio remote-HFL switch 16P connector: disconnected
    With navigation: Audio remote/HFL-navigation voice control switch 16P connector: disconnected
       
    Test point 1 Battery sensor 2P connector (female terminals) No. 2:
    Test point 2 Body ground

    Is there continuity?

    YES 

    Repair a short to ground in the LIN (METER) wire.

    NO 

    The LIN (METER) wire is not shorted. Go to step 6.

  6. Open wire check (LIN (METER) line)

    - 1. Check for continuity between test points 1 and 2.

    Test condition Vehicle OFF (LOCK) mode
    Battery sensor 2P connector: disconnected
    Gauge control module connector A (32P): disconnected
