External Controls

Inspection & Verification 

1. Verify the customer concern by operating the transaxle external control.

   The shift lock actuator locks the gearshift lever in PARK:

   • When the ignition switch lock cylinder is in the LOCK position.
   • With the ignition switch lock cylinder in the RUN position and the brake pedal released.

   The shift lock actuator releases the gearshift lever:

   • When the ignition switch lock cylinder is in the FIRST position.
   • With the ignition switch lock cylinder in the RUN position and the brake pedal actuated.

   Transmission Control Switch (TCS) 

   The transmission control switch (TCS):

   • Seats in the end of the gearshift lever.
     • A cover retains the TCS to the gearshift lever.
   • Is a momentary contact switch.
   • Commands the Powertrain Control Module (PCM), through the Standard Corporate Protocol (SCP) communication network, to disengage or engage the overdrive function of the transaxle.
     • When overdrive D is disengaged, the message O/D OFF will illuminate on the instrument panel.

2. Visually inspect for obvious signs of mechanical and electrical damage, incorrect component installation, and component misalignment. Verify that all circuit-related systems are functioning correctly. Refer to the following chart.
