AT Shift Lock Solenoid and "P" Range Switch: Inspection

  1. CHECK SOLENOID UNIT  .

    Measure the resistance of solenoid unit connector terminals.

    Terminals

    No. 4-No. 3:

    Is the resistance 27.6-30.5 Ω?

    Yes:  Go to  2.

    No:  Replace the solenoid unit. Ref. to CONTROL SYSTEMS>AT SHIFT LOCK SOLENOID AND "P" RANGE SWITCH .

  2. CHECK SOLENOID UNIT  .

    Connect the battery to the solenoid unit connector terminals, and then operate the solenoid.

    Terminals

    No. 3 (+)-No. 4 (-):

    Does the solenoid unit operate normally?

    Yes:  Go to  3.

    No:  Replace the solenoid unit. Ref. to CONTROL SYSTEMS>AT SHIFT LOCK SOLENOID AND "P" RANGE SWITCH .

  3. CHECK "P" RANGE SWITCH  .
    1. Shift the select lever to "P" range.
    2. Measure the resistance between "P" range switch connector terminals.

      Terminals

      No. 1-No. 2:

      Is the resistance less than 1 Ω?

      Yes:  Go to  4.

      No:  Replace the "P" range switch. Ref. to CONTROL SYSTEMS>AT SHIFT LOCK SOLENOID AND "P" RANGE SWITCH .

  4. CHECK "P" RANGE SWITCH  .
    1. Set the select lever to other than "P" range.
    2. Measure the resistance between "P" range switch connector terminals.

      Terminals

      No. 1-No. 2:

      Is the resistance 1 MO or more?

      Yes:  Normal.

      No:  Replace the "P" range switch. Ref. to CONTROL SYSTEMS>AT SHIFT LOCK SOLENOID AND "P" RANGE SWITCH .
