C: INSPECTION

Check the removed cable and replace if damaged, rusty or having problems.

  1. Check the cable for smooth operation.
  2. Check the inner cable for damage and rust.
  3. Check the outer cable for damage, bends and cracks.
  4. Check the boot for damage, cracks and deterioration.
  5. Move the select lever from "P" to "1" range. Check the existence of feel to contact the detents in each range. If the detentes cannot be felt or the position pointer is improperly aligned, adjust the cable.

StepCheckYesNo
1 CHECK SHIFT LOCK SOLENOID. Measure the resistance of shift lock solenoid connector terminals. Terminals No. 4 - No. 5Is the resistance between 20 and 40 ohms?Go to step 2.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. Terminals No. 4 (+) - No. 5 (-)Does the shift lock solenoid operate normally?Go to step 3.Replace the shift lock solenoid and "P" range switch assembly.
3 CHECK "P" RANGE SWITCH. Move the select lever to "P" range. Measure the resistance between "P" range switch connector terminals.Is the resistance less than 1 ohms?Go to step 4.Replace the "P" range switch.
4 CHECK "P" RANGE SWITCH. Set the select lever to other than "P" range. Measure the resistance between "P" range switch connector terminals.Is the resistance more than 1 Mohms?Normal operationReplace the "P" range switch.
