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.
