P0703 - BRAKE SWITCH B INPUT CIRCUIT

Description:  The brake pressure applied (BPA) switch provides a backup signal for the brake pedal position (BPP) switch. If the BPP switch signal is lost, the BPA switch provides the brakes-applied signal to deactivate the speed control system.
Possible Causes: 
  • Open or short in the BPA circuit
  • Damage in module(s) connected to the BPA circuit
  • Damaged brake switch
  • Misadjusted brake switch
Diagnostic Aids:  Check for proper function of the stoplamps. Using the scan tool, check the BPA PID. The stoplamps and PID should toggle on and off with brake pedal activation.
