INSPECTION

STEPCHECKYESNO

1.CHECK SHIFT LOCK SOLENOID.

Measure the resistance of shift lock solenoid connector terminals.

Terminal

No. 4 — No. 5:

Is the resistance between 20 — 40 Ω?

Replace the shift lock solenoid and “P” range switch assembly.

2.CHECK SHIFT LOCK SOLENOID.

Connect the battery to shift lock solenoid connector terminal, and then operate the solenoid.

Terminal

No. 4 (+) — No. 5 (−):

Does the shift lock solenoid operate normally?

Replace the shift lock solenoid and “P” range switch assembly.

3.CHECK “P” RANGE SWITCH.

1) Move the select lever to “P” range.

2) Measure the resistance between “P” range switch connector terminals.

Is the resistance less than 1 Ω?

Replace the “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.

Is the resistance 1 MΩ or more?

Normal operation

Replace the “P” range switch.
