Body Control Module (BCM)
Battery Voltage: Display indicates battery voltage. Measured in volts.
Ignition 1: Display indicates ON when the ignition 1 input circuit of the module receives a battery signal from the ignition switch.
Shift Lock Control Output: Displays the status of the control circuit for the shift lock control solenoid. Active indicates the control circuit is grounded. Inactive indicates that the control circuit is not grounded.
Powertrain Control Module (PCM)
TCC Brake Switch: Displays ON or OFF status of the TCC Brake switch.
TR SW. A/B/C/P: Displays LOW or HI for the state of each of the four inputs from the IMS. LOW displayed indicates a low voltage signal (0 volts) being monitored at the PCM. HI displayed indicates a high voltage signal (B+) being monitored at the PCM.
