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

Measure the resistance of solenoid unit connector terminals.

Terminals 

No. 4 - No. 3:

Is the resistance 27.6 - 30.5 Ω?

Yes:  2

No:  Replace the solenoid unit. Ref. to CONTROL SYSTEMS>AT Shift Lock Solenoid and "P" Range Switch 

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:  3

No:  Replace the solenoid unit. Ref. to CONTROL SYSTEMS>AT Shift Lock Solenoid and "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:  4

No:  Replace the "P" range switch. Ref. to CONTROL SYSTEMS>AT Shift Lock Solenoid and "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 MΩ or more?

Yes:  Normal.

No:  Replace the "P" range switch. Ref. to CONTROL SYSTEMS>AT Shift Lock Solenoid and "P" Range Switch
