Self-Diagnosis Function (Mode 1)
Self-Diagnosis Function (Mode 1)* One second after you go into self-diagnosis function mode 1, the function starts to indicate the diagnosis trouble code (DTC), and repeats the DTC every three seconds.
* From mode 1, disconnect the SCS service connector for five to ten seconds, then reconnect the SCS service connector, and the function goes from mode 1 to mode 2.
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).
