DTC B1195

DTC B1195  : Gauge control module lost communication with Audio Remote Switch (LIN bus connected)

NOTE:  If you are troubleshooting multiple DTCs, be sure to follow the instructions in B-CAN System Diagnosis Test Mode A .

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
   B1195 Gauge control module lost communication with Audio Remote Switch (LIN bus connected)

   Is DTC B1195 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. D24 (5 A)
   Location	Under-dash 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 +B wire.

3. Determine possible failure area (audio remote-HFL switch power and ground, LIN (START SW)/STRG SW LIN line)

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

   -2. Disconnect the following connector.

   Audio remote-HFL switch 12P connector

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

   Test condition	Vehicle OFF (LOCK) mode Audio remote-HFL switch 12P connector: disconnected
   Test point 1	Audio remote-HFL switch 12P connector No. 7
   Test point 2	Audio remote-HFL switch 12P connector No. 10

   Is there battery voltage?

   YES 

   Go to step  5.

   NO 

   Go to step 4.

4. Open wire check (+B line)

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

   Test condition

   Vehicle OFF (LOCK) mode Audio remote-HFL switch 12P connector: disconnected

   Test point 1	Audio remote-HFL switch 12P connector No. 7
   Test point 2	Body ground

   Is there battery voltage?

   YES 

   Repair an open or high resistance in the ground wire or poor ground (G401).

   NO 

   Repair an open or high resistance in the wire.

5. Shorted wire check (LIN (START SW)/STRG SW LIN 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 Audio remote-HFL switch 12P connector: disconnected
   Test point 1	Audio remote-HFL switch 12P connector No. 12
   Test point 2	Body ground

   Is there continuity?

   YES 

   Repair a short to ground in the wire.

   NO 

   The LIN (START SW)/STRG SW LIN wire is not shorted. Go to step 6.

6. Open wire check (LIN (START SW)/STRG SW LIN line)

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

   Test condition	Vehicle OFF (LOCK) mode Gauge control module connector A (32P): disconnected Audio remote-HFL switch 12P connector: disconnected
   Test point 1	Gauge control module connector A (32P) No. 23
   Test point 2	Audio remote-HFL switch 12P connector No. 12

   Is there continuity?

   YES 

   The LIN (START SW)/STRG SW LIN wire is OK. Replace the audio remote-HFL switch . If the DTC is still present, replace the gauge control module .

   NO 

   An open or poor connection in the wire.
