    • Connect the scan tool.
    • Ignition ON.
    • Enter the following diagnostic mode on the scan tool: DataLogger - ABS Module.
    • Press and release the brake pedal while monitoring the BOO_ABS PID.
    • Does the PID display ON with the brake pedal applied and OFF with the brake pedal released? 
      • Yes  : GO to  G3.
      • No  : GO to G2.
  2. G2 MONITOR THE PCM BRAKE ON/OFF (BOO1) PID 
    • Enter the following diagnostic mode on the scan tool: DataLogger - PCM.
    • Press and release the brake pedal while monitoring the BOO1 PID.
    • Does the PID display ON with the brake pedal applied and OFF with the brake pedal released?

    • Enter the following diagnostic mode on the scan tool: DataLogger - ABS Module.
    • With the brake pedal not applied, record the pressure displayed by the BRAKPRES PID.
    • Is the initial brake pressure less than 275 kPa (40 psi) with the brake pedal not applied? 
  4. G4 MONITOR THE BRAKPRES PID WHILE APPLYING THE BRAKE PEDAL 
    • Enter the following diagnostic mode on the scan tool: DataLogger - ABS Module.
    • Firmly press and release the brake pedal while monitoring the BRAKPRES PID.
    • Does the PID increase with firm pressure on the brake pedal and then decrease with the brake pedal released? 
      • Yes  : The system is operating correctly at this time. TEST the system for normal operation.
