Shift Lock Solenoid Test/Replacement
Test:
1. Remove the console, then disconnect the 3-P con-
nector of the shift lock solenoid from the floor wire
harness.
NOTE: This solenoid has a diode in it. To get an
accurate reading, either test it with a volt-ohmmeter
that compensates for diodes, or make sure you con-
nect your test leads to match the polarity shown.
2. Connect battery power to the A terminal and
ground to the B terminal momentarily, and check to
see if the solenoid works.
• If it does not work, replace it.
• If it works, go to step 3.
3. When the shift lock solenoid is ON, check that there
is a clearance of 2.5 ± 0.5 mm (0.098 ± 0.020 in)
between the top corner of the shift lock lever and
the side of the lock pin.

• If clearance is correct, go to next step.
• If clearance is incorrect, loosen the self-locking
nuts and adjust the solenoid as needed.
