Body Control Module (BCM)

Battery Voltage Signal: Display indicates battery voltage. Measured in volts.

Shift Lock Solenoid Command: Displays the status of the shift lock control solenoid. Lock indicates the control circuit is grounded. Unlock indicates that the control circuit is not grounded.

Engine Control Module (ECM)/Powertrain Control Module (PCM)

BPP Circuit Signal: Displays Applied or Released status of the brake switch.

IMS A/B/C/P: Displays LOW or HI for the state of each of the 4 inputs from the internal mode switch (IMS). LOW displayed indicates a low voltage signal (0 volts) being monitored at the engine control module (ECM). HI displayed indicates a high voltage signal (B+) being monitored at the ECM.

Initial Brake Apply Signal: Displays Applied or Released status of the brake switch.

TCC Brake Switch: Displays Open or Closed status of the torque converter clutch (TCC) brake switch.

TR Sw. A/B/C/P: Displays LOW or HI for the state of each of the 4 inputs from the IMS. LOW displayed indicates a low voltage signal (0 volts) being monitored at the powertrain control module (PCM). HI displayed indicates a high voltage signal (B+) being monitored at the PCM.
