CONTROL SYSTEMS
C: INSPECTION
Step
1 CHECK SHIFT LOCK SOLENOID.
Measure the resistance of shift lock solenoid
connector terminals.
Terminals
No. 4 — No. 3:
2 CHECK SHIFT LOCK SOLENOID.
Connect the battery to shift lock solenoid con-
nector terminal, and then operate the solenoid.
Terminals
No. 3 (+) — No. 4 (–):
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:
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:
Check
Is the resistance 19.8 — 24.2 ? Go to step 2.
Does the shift lock solenoid
operate normally?
Is the resistance less than 1 ? Go to step 4.
Is the resistance 1 M or
more?
CS-30
Yes No
Replace the shift
lock solenoid.
Go to step 3. Replace the shift
lock solenoid.
Replace the P
