Test I: The Stoplamps Are Inoperative

PINPOINT TEST I: THE STOPLAMPS ARE INOPERATIVE

I1-I2:

I2-I4:

I5-I6:

Normal Operation
For all vehicles, the stoplamp switch is supplied voltage through circuit SBP04 (GN/RD) from the smart junction box (SJB). When the brake pedal is applied, the stoplamp switch routes voltage to the SJB through circuit CCB08 (VT/WH).

For the Milan and MKZ, the voltage is then routed to the stoplamps through circuit CLS17 (YE/GY).

Possible Causes
- Fuse
- Circuit CCB08 (VT/WH) open
- Circuit CLS17 (YE/GY) open
- Circuit SBP04 (GN/RD) open
- Stoplamp switch
- SJB
