Diagnostic Trouble Code (DTC) Table
NOTE: If no DTCs are indicated, but you know the system is abnormal, check these items:

If the light does not come on and the buzzer does not beep, check the continuity between the BLK wire of the multiplex control inspection
connector and body ground.

If either the light or the beep indicates the DTC(s), check the continuity between the PNK/BLK wire of the multiplex control inspection connector
and multiplex control units (driver's and passenger's).
