the 16-pin connector. It should indicate continuity. If not, check sonic welds no. 1 and no. 2.
3.
Probe pin 2 (red/white wire). It should show BPV. If not, check 2-amp fuse.
See following NOTE.
NOTE:
The red/white wire has BPV with the Run/Tow switch in either position.
4.
Probe pin 4 (white/black wire). It should show approximately 13 volts supplied by the controller. If not, check
wiring and then controller.
See following NOTE.
NOTE:
The white/black wire only has voltage with the Run/Tow switch in the RUN position.
If pin 4 has no voltage, the controllers LIN (Local Interconnect bus) may have failed. The vehicle can be driven
if it is not used with Guardian or Visage and will not show any symptoms. Otherwise, Guardian or Visage will
disable the vehicle until communication is restored.
