    When the integrated drive-mode switch (↓) is pressed 

    Signal Threshold Current conditions
    Values Unit Values Unit

    Integrated drive-mode switch 5P connector

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

    Test condition Vehicle OFF (LOCK) mode
    Gauge control module connector A (32P): disconnected
    Integrated drive-mode switch 5P connector: disconnected
    Test point 1 Gauge control module connector A (32P) No. 8 
    Test point 2 Integrated drive-mode switch 5P connector No. 4

  4. Shorted wire check (MODE UP, MODE DOWN lines)

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

    Test condition Vehicle OFF (LOCK) mode
    Gauge control module connector A (32P): disconnected
    Integrated drive-mode switch 5P connector: disconnected
    Test point 1 Gauge control module connector A (32P) No. 8 
    Test point 2 Body ground
    Test point 1 Gauge control module connector A (32P) No. 25 
    Test point 2 Body ground

    Is there continuity?

    YES 

    Repair a short to ground in the wire.

    NO 

    The MODE UP and MODE DOWN wires are OK. Go to step 5.

  5. Open wire check (GND line)

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

    Test condition Vehicle OFF (LOCK) mode
    Gauge control module connector A (32P): disconnected
    Integrated drive-mode switch 5P connector: disconnected
    Test point 1 Integrated drive-mode switch 5P connector No. 5
