   Replace the fuse. If the fuse blows again, repair a short to ground in the No. No. C16 (10 A) fuse circuit.

3. Open wire check (+B BACK UP line)

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

   - 2. Disconnect the following connector.

   With navigation: Audio remote/HFL-navigation voice control switch 16P connector Without navigation: Audio remote-HFL switch 16P connector

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

   Test condition	Vehicle OFF (LOCK) mode With navigation: Audio remote/HFL-navigation voice control switch 16P connector: disconnected Without navigation: Audio remote-HFL switch 16P connector: disconnected
   Test circuit	+B BACK UP
   Test point 1	With navigation: Audio remote/HFL-navigation voice control switch 16P connector No. 16 (GRN) Without navigation: Audio remote-HFL switch 16P connector No. 16 (GRN)
   Test point 2	Body ground

   Is there battery voltage?

   YES 

   The +B BACK UP wire is OK. Go to step 4.

   NO 

   Repair an open or high resistance in the wire.

4. Open wire check (SGND line)

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

   Test condition	Vehicle OFF (LOCK) mode With navigation: Audio remote/HFL-navigation voice control switch 16P connector: disconnected Without navigation: Audio remote-HFL switch 16P connector: disconnected
   Test circuit	SGND
   Test point 1	With navigation: Audio remote/HFL-navigation voice control switch 16P connector No. 1 (BLK) Without navigation: Audio remote-HFL switch 16P connector No. 1 (BLK)
   Test point 2	Body ground

   Is there continuity?

   YES 

   The SGND wire is OK. Go to step 5.

   NO 

   Repair an open or high resistance in the ground wire or poor ground (G507).

5. 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 With navigation: Audio remote/HFL-navigation voice control switch 16P connector: disconnected Without navigation: Audio remote-HFL switch 16P connector: disconnected
   Test circuit	LIN (METER)
   Test point 1	Gauge control module connector A (32P) No. 24 (ORN)
   Test point 2	With navigation: Audio remote/HFL-navigation voice control switch 16P connector No. 14 (BLU) Without navigation: Audio remote-HFL switch 16P connector No. 14 (BLU)

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

   Is there continuity?

   YES 

   Replace the audio remote/HFL-navigation voice control switch (with navigation) or the audio remote-HFL switch (without navigation) - Refer to: ANC/Active Sound Control Microphone Removal and Installation (2014 2015 2016) .

   NO 

   An open or poor connection in the LIN (METER) wire between the gauge control module and the steering commander switch assembly.

6. Shorted wire check (LIN (METER) line)

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

   - 2. Disconnect the following connectors.

   With navigation: Audio remote/HFL-navigation voice control switch 16P connector Without navigation: Audio remote-HFL switch 16P connector Gauge control module connector A (32P) Battery sensor 2P connector - Refer to: 12 Volt Battery Sensor Removal and Installation (2016 2017 2018 2019 2020), or 12 Volt Battery Sensor Removal and Installation (2014 2015)

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

   Test condition	Vehicle OFF (LOCK) mode With navigation: Audio remote/HFL-navigation voice control switch 16P connector: disconnected Without navigation: Audio remote-HFL switch 16P connector: disconnected Gauge control module connector A (32P): disconnected Battery sensor 2P connector: disconnected
