DTC B1192: Gauge Control Module Lost Communication With Battery Sensor ECU (LIN BUS Connected)

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 .

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)

   Is DTC B1192 indicated?

   YES 

   Go to step 2.

   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. A16 (10 A)
   Location	Under-hood fuse/relay 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. A16 (10 A) fuse circuit.

3. Open wire check (+B HORN line)

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

   - 2. Disconnect the following connector:

   Battery sensor 3P connector

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

   Test condition	Vehicle OFF (LOCK) mode Battery sensor 3P connector: disconnected
   Test circuit	+B HORN
   Test point 1	Battery sensor 3P connector No. 2 (RED)
   Test point 2	Body ground

   Is there battery voltage?

   YES 

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

   NO 

   Repair an open or high resistance in the wire.

4. Open wire check (LIN (BATT SENSOR) 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 3P connector: disconnected
   Test circuit	LIN (BATT SENSOR)
   Test point 1	Gauge control module connector A (32P) No. 23 (LT BLU)

   Test point 2

   Battery sensor 3P connector No. 3 (LT BLU)

   Is there continuity?

   YES 

   The (LIN (BATT SENSOR) wire is not open. Go to step 5.

   NO 

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

5. Shorted wire check (LIN (BATT SENSOR) line)

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

   Test condition	Vehicle OFF (LOCK) mode Battery sensor 3P connector: disconnected Gauge control module connector A (32P): disconnected
   Test circuit	LIN (BATT SENSOR)
   Test point 1	Battery sensor 3P connector No. 3 (LT BLU)
   Test point 2	Body ground

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

   Is there continuity?

   YES 

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

   NO 

   The LIN (BATT SENSOR) wire is OK. Replace the battery sensor .
