STEP 20. Check harness for short circuit to ground 
between combination meter connector D-32 terminal 2 and 
joint connector D-116 terminal 33.
Q: Is the harness wire in good condition?

YES : Go to Step 5.
NO :  Repair or replace the harness wire.

STEP 21. Check the transmission range switch.
Measure the resistance between the terminals for each selec-
tor position as indicated in the table above.

Q: Does the resistance measure less than 2 ohms for each 

selector position?
YES : Go to Step 22.
NO :  Replace the transmission range switch. Refer to 

GROUP 23B, Transmission
