Steering Lock Replacement
SRS components are located in this area. Review the
SRS component locations, precautions, and procedures
in the SRS section (23) before performing repairs or ser-
vice.
NOTE: The original radio has a coded theft protection
circuit. Be sure to get the customer's code number before- disconnecting the battery.- removing the No. 47 (7.5 A) fuse trom the under-hood
fuse/relav box.- removing the radio.
After service, reconnect power to the radio and turn it
on. When the word "CODE" is displayed. enter the cus-
tomer's 5-digit code to restore radio operation.
1. Disconnect the negative cable from the battery.
2. Remove ths dsshboard lower cover and knee bolster(s6o p8ge 23-72).
3, Disconnect the 5P connector from the under-dash
fuse/relay box and the 7P connsctor from th€ main
wire harness (see page 23-72l.,
4. Remove the steering column covars (see page
23-721.
5. Remove the column holder mounting bolts and nuts.

Lower the stee.ing column assembly.
Center-ounch each of the two shear bolts and drill
their heads oft with a 5 mm {3/16 in) drill bit.
CAUTION: Do not damage the switch body when
lemoving th€ sheal bolts.
Remove the shear bolts from the switch body.
Install the new ignition switch without the key in-
serted.
1O. Loosely tighten the new shear bolts.
11. Ins€rt the ignition key and check for proper opera-
tion of the sleering wheel lock and that the ignition
key turns freely.
12. Tighten the shear bolts until the hex heads twist off.

Ch6ck Starter Engag€mont;
1. Remove the No. 44 (15 A) fuse from the under-hood
fuse/relay box,
Press the clutch pedal all the way in (M/T), and turn
the ignition switch to "St8rt". The staner should
crank the engine,
NOTE: On cars equipped with manual transmission,
the engine will not crank unless the clutch pedal is
fully depressed.
lf the starter does not crank the engine, go to step 3.
Check the battery, battery positive cable, ground,
and the wire connections for looseness and cor-
rosion.
Test again. lf the stsner stilldoes not crank the en-
gine, go to step 4.
Bypass the ignition switch circuit as follows {make
sure the transmission is in neutral)
Unplug the connector (BLKMHT wire and solenoid
terminal) trom the staner. Then connect a jumper
wire from the batterv positive (+ ) terminal to the
solenoid terminal. The starter should crank the
engine.
a It the stsrter still does not crank the engine,
replace it and diagnose its internal problems,
a lf the starter cranks the engine. go to step 5.
(cont'd)
4.
NOTE: The air temperature must be between 59 and
100oF {15 and 38'C) betore testing.
Recommended Procedure:
a Use a starter system tester.
a Connect and operate the equipment in accordance
with the manufacturer's instructions.
a Test and troubleshoot as described.
Alternate Procodure:
a Use the following equipment;- Ammeter, O-400 A- Voltmeter. O-20 V (accurate within O,1 volt)- Tachometer, O- 1 2OO rpm
a Hook up voltmeter and ammeter as shown.
NEGATIVE TERMINAL
NOTE: Atter this test, or any subsequent repalr,
reset the ECM to clear any codes (see section 1 1).

Starting System
Starter Test (cont'dl
Check Cranking rpmr
Engine speed during cranking should be above 1OO rpm.
lJ speed is too low, check for:
a Loose batlery or starter terminals
a Excessively worn starter brushes
a Open circuit in commutator segments
a Dirty or damaged helical spline or drive gear
a Defective drive gear overrunning clutch
Check Starter Disengagement:
Press the clutch pedal all the way in (M/T), turn rhe igni
tion switch to "lll" and release to "11".
The starter drive gear should disengage from the flywheel
or torque converter ring gear when you release the key.
It the drive gear hangs up on the flywheel or torque con-
verter ring gear, check for:
a Solenoid plunger and switch mallunction
a Dirty drive gear assembly or damaged overrunning
clutch
5. Check for an open in the BLK/WHT wire circuit be
tween the starter and ignition switch, and con-
necrors,
6. Check the ignition switch (see page 23-71).
7. On cars with automatic transmission, check the A/Tgear position switch (neutral position switch) and
connector. On cars with manualtransmission, check
the starter cut relay, clutch interlock switch, and
connectors.
NOTE: Check the No. 42 (40 A) fuse in the under,hoodfuse/relay box for the starter cut relay.
Check Jor Wear and Damage:
The starter should crank the engine smoothly and stead,ily. lf the starter engages, but cranks the engine errati
cally, remove it. Inspect the starter, drive gear, andllywheel or torque converter ring gear lor damage.
a Check the drive gear overrunning clutch for binding
or slipping when the armature is rotated with the drivegear held. Replace the gears i{ damaged.
Check CJanking Voltage and Current Draw:
Cranking voltage should be no less than 8.O volts.
Current draw should be no more than * amperes.* 1.2 kW: 27O A
1 .4 kW: 360 A
It cranking voltage is too low, or current draw too high,check for:
a Dead or low charged batterya Open circuit in starter armature commutator segmentsa Starter armalure dragging
a Shorted armature windinga Excessive drag in engine
