"Y" Body

  1. Disconnect brakelight switch 4-pin connector C2 and BTSI solenoid 4-pin connector. Turn ignition switch to ON position. Measure voltage between brakelight switch 4-pin connector C2 terminal "B" and ground. See Figure. If voltage is not 10-14 volts, go to next step. If voltage is 10-14 volts, check for short to battery power in circuit between brakelight switch 4-pin connector C2 terminal "B" and BTSI solenoid 4-pin connector terminal "C". See Figure. See WIRING DIAGRAMS . Repair as necessary, then go to step  3.
  2. Turn ignition switch to OFF position. Reconnect brakelight switch 4-pin connector C2. Apply brake pedal and measure voltage between BTSI solenoid 4-pin connector terminal "C" and ground. See Figure. If voltage is 10-14 volts, replace brakelight switch, then go to next step. If voltage is not 10-14 volts, replace BTSI solenoid, then go to next step.
  3. Ensure all components disconnected or removed during testing are reconnected and installed on vehicle. Ensure BTSI system operates correctly. See SHIFT INTERLOCK SOLENOID  under DESCRIPTION & OPERATION. If system does not operate correctly, repeat step  1.
