   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. B4 - Refer to: Fuse to Components Index (With Auto Idle Stop System) (2019 2020 2021) or Fuse to Components Index (Without Auto Idle Stop System) (2019 2020 2021) .

   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. B4 fuse circuit.

3. Open wire check (+B BMS line)

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

   - 2. Disconnect the following connector.

   12 volt battery sensor 2P connector

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

   Test condition	Vehicle OFF (LOCK) mode 12 volt battery sensor 2P connector: disconnected

   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 12 volt battery sensor 2P connector: disconnected
   Test point 1	12 volt battery sensor 2P connector (female terminals) No. 2: (1)
   Test point 2	Gauge control module connector A (32P) No. 23 - Refer to: Gauge Control Module Connector for Inputs and Outputs (2019) or Gauge Control Module Connector for Inputs and Outputs (2020 2021) .
