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

DIAGNOSIS PROCEDURE

Step Check Yes No
1 CHECK SHIFT LOCK SOLENOID. 
Measure the resistance of shift lock solenoid connector terminals.

Terminals 

No. 4 - No. 3: 

 Is the resistance between 12 and 18 Ω? Go to step 2.  Replace the shift lock solenoid.
2 CHECK SHIFT LOCK SOLENOID. 
Connect the battery to shift lock solenoid connector terminal, and then operate the solenoid.

Terminals 

No. 3 (+) - No. 4 (-): 

 Does the shift lock solenoid operate normally? Go to step 3.  Replace the shift lock solenoid.
3 CHECK "P" RANGE SWITCH. 
  1. Move 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? Go to step 4.  Replace the "P" range switch.
4 CHECK "P" RANGE SWITCH. 
  1. Set the select lever to a range other than the "P" range.
  2. Measure the resistance between "P" range switch connector terminals.

Terminals 

No. 1 - No. 2: 

 Is the resistance more than 1 MΩ? Normal operation Replace the "P" range switch.
