DTC B1192 (2014 2015 2016)

DTC B1192  : Gauge control module lost communication with battery sensor ECU (LIN BUS connected)

DTC (Gauge Control Module)

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)

   Is DTC B1192 indicated?

   YES 

   Go to step 2.

   YES 

   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 - Refer to: 12 Volt Battery Sensor Removal and Installation (2014 2015), or 12 Volt Battery Sensor Removal and Installation (2016 2017 2018 2019 2020)

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

   Test condition	Vehicle OFF (LOCK) mode Battery sensor 2P connector: disconnected
   Test circuit	+B BMS
   Test point 1	Battery sensor 2P connector No. 1 (BRN)
   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 circuit	LIN (METER)
   Test point 1	Battery sensor 2P connector No. 2 (ORN)
   Test point 2	Gauge control module connector A (32P) No. 24 (ORN)

   Courtesy of HONDA, U.S.A., INC.

   Is there continuity?

   YES 

   Replace the battery sensor - Refer to: 12 Volt Battery Sensor Removal and Installation (2016 2017 2018 2019 2020), or 12 Volt Battery Sensor Removal and Installation (2014 2015) .

   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 - Refer to: 12 Volt Battery Sensor Removal and Installation (2014 2015) or 12 Volt Battery Sensor Removal and Installation (2016 2017 2018 2019 2020), Gauge control module connector A (32P) Audio remote-HFL switch 16P connector (without navigation) Audio remote/HFL-navigation voice control switch 16P connector (with navigation)

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

   Is there continuity?

   YES 

   Repair a short to ground in the LIN (METER) wire between the gauge control module and the battery sensor.

   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.
