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.

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):

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):

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):

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.?
