Power not available to reminder. Refer to page
8A-75-0 through 8A-77-0 for electrical diagnosis.
Open in chassis wiring. Check by separating
chassis-to-column connector. Connect terminals
"E" and " F " female contacts on the chassis
connector (a bent paper clip will work). If the
reminder sounds, repair chassis wiring. If the
reminder does not sound, go to Step A.
A. Connect a continuity meter (light) to the
male "E" and " F " column connector
contacts. Push the key all the way into the
lock cylinder. If the light is on when the key
is in, and off when the key is out, the
function is normal. If the light is not on, the
fault is in the column. Go to Step B.
B. Disassemble the upper end of the column
until the turn signal switch mounting
screws have been removed. Lift the turn
signal switch and check the probes of the
reminder switch to ensure good contact
with the pads on the signal switch. Bend the
probes, if needed, then replace the turn
signal switch and tighten the three screws.
Check the function as in Step A.
Short or fault in the turn signal switch wiring.
Connect male "E" and " F " contacts of column
connector with jumper. Check key reminder
switch pads on turn signal switch with continuity
meter. If there is continuity, the function is
normal. If not, replace the turn signal switch.
If the problem has not been found, connect a
continuity meter (light) to the reminder switch
probes on the switch. Fully insert and remove the

key from the lock cylinder. If the light is on when
the key is in the lock cylinder, and off when the
key is out, the function is normal. Retrace the
diagnostic steps starting at Step A. If the light is
not on, the fault is in the lock cylinder or
reminder switch.
5. Chips, burrs, or foreign material in the lock
cylinder preventing actuator tip function.
Remove chips, burrs, etc. Reassemble and
recheck (Step 4). The key must be removed, or
the cylinder must be in the "Run" position,
before the lock cylinder can be removed.
6. Damaged lock cylinder. With the lock cylinder
removed, push the key all the way in, then
remove it. The lock cylinder actuator tip should
extend and retract smoothly. Total extension of
tip should be 1.27 mm (.050"). If not, replace the
lock cylinder. Remove and clean as required.
Reassemble and recheck per Step 4.
7. Switch appears good but will not operate.
Connect continuity meter leads to the reminder
switch probes on the switch. Press on the actuator
