  Q: How to replace the Park/Neutral Safety Switch Assy (ATM) on Scion xA?

  A:

  The first step to replace the park/neutral position switch assy (ATM) involves removing the battery. The transmission control cable assembly must be separated through removal of the nut which detaches the control cable from the control shaft lever and the clip which disconnects the cable from the control cable bracket. To begin replacement remove the park/neutral position switch assembly connector before taking out the nut while removing the washer and control shaft lever. After that disconnect the manual valve shaft lock plate then unscrew the manual valve shaft nut. You need to unfasten the two bolts before extracting the park/neutral position switch assembly from its position. When installing the park/neutral position switch assembly onto the manual valve shaft users should place it first then add a new lock plate before torquing the manual valve shaft nut to 6.9 Nm (70 kgf-cm, 61 inch lbs.). First properly install the two bolts along with the control shaft lever by counterclockwise rotation until it stops then clockwise two notches before removing it temporarily. Use the neutral basic line to position the groove before tightening the two bolts to 5.4 Nm (55 kgf-cm, 48 inch lbs) while holding the switch in place. Begin the installation by using a screwdriver on the nut combined with the lock plate before installing all components including the washer, control shaft lever and nut with a torque setting at 13 Nm (130 kgf-cm, 9 ft. lbs.). The finishing steps include attaching the connector to the park/neutral position switch assembly followed by cable installation to the control shaft lever through the nut which leads to installation of the control cable to the bracket with a new clip. The technician performs a shift lever position check and verifies the park/neutral position switch assembly.

  Q: How to service and repair the park/neutral safety switch on Scion xA?

  A:

  Initiating the park/neutral position switch service or repair process requires checking three vehicle conditions including enabling the parking brake followed by turning the ignition switch on and depressing the brake pedal to ensure engine operation only in n or p positions and verifying back up light and reverse warning buzzer functions in r but not other positions. The park/neutral position switch assembly requires removal through connector disconnection and removal of the nut followed by washer and control shaft lever. The switch can be extracted when the manual valve shaft nut and two bolts are removed and the lock washer is pried free. Check the switch assembly through resistance measurements in each position; if values fall outside specifications then get a new switch assembly. To adjust the switch, locate its two bolts then move the shift lever to n position and match the groove with the neutral basic line before tightening the bolts at 5.4 Nm (55 kgf-cm, 48 inch lbs.). Reinstallation of the park/neutral position switch assembly requires fitting it to the manual valve shaft followed by two bolt mounting then a new lock washer addition before manual valve shaft nut tightening reaches 6.9 Nm (70 kgf-cm, 61 inch lbs.). First place the control shaft lever temporarily then turn it counterclockwise until it stops before turning clockwise two notches. Remove the lever and align the groove with the neutral basic line while holding the switch to tighten the bolts to 5.4 Nm (55 kgf-cm, 48 inch lbs.). Attach the screwdriver staked lock washer to the nut before installing the control shaft lever with its washer and nut to 12.7 Nm (130 kgf-cm, 9 ft. lbs.) torque while connecting the connector to the park/neutral position switch. The installation process for transmission control cable assembly includes attaching the control cable to the control shaft lever through the nut and installing it to the bracket using a new clip before reinstalling the battery. The worker should perform a position check of the shift lever before completing a final inspection of the park/neutral position switch assembly.
