IGNITION SWITCH
DESCRIPTION
The ignition switch (5) is located on the steering col-
umn (4). It is used as the main on/off switching device
for most electrical components. The mechanical key
cylinder is used to engage/disengage the electrical
ignition switch.
OPERATION
Vehicles equipped with an automatic transmission and a steering column mounted shifter: an interlock
device is located within the shift cable. This interlock device is used to lock the transmission shifter in the PARK
position when the key cylinder is in any position and the brake pedal is not depressed.
DIAGNOSIS AND TESTING
IGNITION SWITCH
TEST AND REPAIR
If the key removal effort is excessive on a vehicle with a automatic transmission first adjust the shift linkage, (Refer
to 21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - 46RE/GEAR SHIFT CABLE - ADJUSTMENTS).
If the ignition switch effort is excessive remove the ignition key cylinder from the steering column. (Refer to 19 -
STEERING/COLUMN/LOCK CYLINDER HOUSING - REMOVAL). Check the turning effort of the key cylinder. If the
ignition key cylinder effort is excessive replace the key cylinder.
REMOVAL
SERVICE PRECAUTIONS
NOTE: The steering column on vehicles equipped
with an automatic transmission is not equipped
with an internal locking shaft with the ignition cyl-
inder. Alternative methods of locking the steering
wheel for service will have to be used.
The tilt and standard column (4) have been designed
to be serviced as an assembly; without wiring,
switches, shrouds, steering wheel, etc. Most steering
column components can be serviced without removing
the steering column from the vehicle.
Safety goggles should be worn at all times when
working on steering columns.
