Press the brake pedal and measure the voltage between No. 1 terminal of the shift lock solenoid connector and body ground. SHIFT LOCK SOLENOID CONNECTOR Wire side of female terminals Is there battery voltage when pressing the brake pedal? YES - Go to step 13. NO - Repair open or short in the wire between the No. 1 terminal of the shift lock solenoid connector and the multiplex control unit. Measure the voltage at the shift lock solenoid connector terminals with pressing the brake pedal. SHIFT LOCK SOLENOID CONNECTOR Wire side of female terminals Is there battery voltage when pressing the brake pedal? YES - Go to step 14. NO - Check for an open in shift lock solenoid ground wire between the No. 2 terminal of the shift lock solenoid connector and the multiplex control unit. If the wire is OK, check for an opeNmultiplex control unit ground wire and poor ground.

Connect the No. 1 terminal of the shift lock solenoid connector to the battery positive terminal and connect the No. 2 terminal to the battery negative terminal. Check that the shift lock solenoid operates. NOTE: Do not connect the No. 2 terminal to the battery positive terminal or you will damage the diode inside the shift lock solenoid. SHIFT LOCK SOLENOID Terminal side of female terminals Does the shift lock solenoid operate properly? YES - Check for shift lever shift lock mechanism. If necessary, substitute a known-good multiplex control unit and recheck. NO - Replace the shift lock solenoid.
