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 .
• Before troubleshooting, make sure the fuses and relays associated with the system is OK.

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. 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 4.

   NO 

   Go to step 3.

3. Open wire check (+B line)

   -1. 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	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.

4. Shorted wire check (LIN (START_SW) / STRG_SW_LIN line)

   -1. Disconnect the following connector.

   Gauge control module connector A (32P)

   -2. Measure the resistance 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 1.0 MΩ or more?

   YES 

   The LIN (START_SW) / STRG_SW_LIN wire is not shorted. Go to step 5.

   NO 

   Repair a short to ground in the wire.

5. Open wire check (LIN (START_SW) / STRG_SW_LIN line)

   -1. Measure the resistance 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 1.0 Ω or less?

   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.
