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

DIAGNOSTIC PROCEDURE

Step Check Yes No
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? Go to step 2  . Replace the solenoid unit. <Ref. to 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? Go to step 3  . Replace the solenoid unit. <Ref. to 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? Go to step 4  . Replace the "P" range switch. <Ref. to 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 MΩ or more? Normal Replace the "P" range switch. <Ref. to AT SHIFT LOCK SOLENOID AND "P" RANGE SWITCH .>
