Pinpoint Test E: CHECK THE INTERLOCK SOLENOID CIRCUIT
- CHECK THE INTERLOCK SOLENOID GROUND
Disconnect the interlock solenoid electrical connector, FC86.
Measure the resistance between FC86, pin 02 (B) and GROUND.
Is the resistance greater than 5 ohms?
YES: REPAIR the high resistance circuit. For additional information, refer to the wiring diagrams. TEST the system for normal operation.
NO: Go to step 2.
- CHECK THE INTERLOCK SOLENOID OUTPUT FROM BPM
Turn the ignition switch to the ON position.
Apply the footbrake.
Measure the voltage between FC86, pin 01 (OG) and GROUND.
Is the voltage less than 10 volts?
YES: Go to step 3.
NO: INSTALL a new interlock solenoid. Refer to Brake Shift Interlock Actuator - Removal and Installation . TEST the system for normal operation.
- CHECK THE INTERLOCK SOLENOID OUTPUT CIRCUIT FROM BPM FOR HIGH RESISTANCE
Disconnect the battery negative terminal.
Disconnect the BPM electrical connector, FC14.
Measure the resistance between FC86, pin 01 (OG) and FC14, pin 48 (OG).
Is the resistance greater than 5 ohms?
YES: REPAIR the high resistance circuit. For additional information, refer to the wiring diagrams. TEST the system for normal operation.
NO: Check for DTCs indicating a brake switch malfunction. Check the brake switch signal to the BPM (SCP network)
