SRS components are located in this area. Review lhe
SRS component locations, precautions, and procedures
in the SRS section (24) before performing repairs or ser-
vice.
Removal:
1. Make sure you have the anti-lheft code for the radio
then write down the frequencies lor the radio's pre-
set buttons ('99 - 00 modelsl.
2. Disconnect the battery negative cable. then discon
nect the positive cable, and wait at least three min
utes,
3. Disconnect the airbag connectors (see section 24)'
4. Remove the driver's dashboard lower cover and
knee bolster (see section 20)
5. Remove the two mounting nuts, and pull the under
dash fuse/relay box out from under the dash'
6. Disconnect the connectors from the under-dash
fuse/relay box, and take out the under-dash fuse/
relay box (see section 24).
lnstallation:
1. Connect the connectors to the under-dash tuse/
relay box, then install the under dash fuse/relay box
in the reverse order of removal (see section 24)'
2. Install the driver's dashboard lower cover (see sec
tion 20).
3. Connect the airbag connectors {see section 24)
4. Connect the battery positive cable, then connect the
negative cable.
5. Enter the anti-theft code lor the radio, then enter the
customer's radio station presets ('99 - 00 models)'
6. Confirm that all sYstems work properly'

-Starter Test
NOTE; The air temoerature must be between 59 and
100'F (15 and 38"C) before testing.
Recommended Procedure:
. Use a staner system tester.
. Connect and operate the equipment in accordance
with the manufacturer's instructions.
. Test and troubleshoot as described,
Alternate Procedurg:
. Use the following equipment:- Ammeter, 0 - 400 A
- Voltmeter, 0 - 20 V (accurate within 0.1 volt)
- Tachometer, 0 - 1,200 rpm
. Hook up a voltmeter and ammeter as shown.
NEGATIVETERMINAL
NOTE: After this test, or any subsequent repair. reset
the ECM/PCM to clear any codes (see section l1)
Check the Start€r Engagemont:
1. Remove the No. 44 (15 A) fuse from the under-hood
fuse/relay box,
2. Turn the ignition switch to START (llll with the shift
lever in E or E position (rVT) or with the clutch pedal
depressed {M/T). The starter should crank the engine.
. lf the starter does not crank the engine, go to
step 3.
. lf itcranksthe engineerraticallyortooslowly, go
to "Check for Wear and Damage" on the next
page.
Check the battery. battery positive cable, ground,
starter cut relay, and the wire connections for loose-
ness and corrosion, Test again.
lf the starter still does not crank the engine, go to
step 4,
Unplug the connector (BLK,/WHT wire and solenoid
terminal) from the starter,
Connect a jumper wire from the battery positive (+)
terminal to the solenoid terminal.
The starter should crank the engine.
. lf the starter still does not crank the engine,
remove it, and diagnose its internal problem
. lf the startercranksthe engine, goto step 6.
Check the ignition switch (see page 23-891.
Check the starter cut relay and clutch interlock switch
(see page 23-86,87).
Check the A/f gear position switch (see page 23-154).
Check for an open in the wire between the ignition
switch and starter.

Jlgnition Control Module (lCMl Input Test
NOTE:
. See section 1'l when the malfunction indicator lamp
(MlL) turned on.
. Perform an input test for the ignition control module
(lCM) after finishing the fundamental tests for the
ignition system and the fuel and emissions systems
1. Remove the distributor ignition (Dl) cap, the distrib-
utor ignition (Dl) rotor and the leak cover (TEC).
2. Disconnect the wires from the lCM.
HITACHI:
BLK/YEL
TEC:
Turn the ignition switch ON (ll). Check for voltage
between the BLK/YEL wire and body ground.
There should be battery voltage.
. lf there is no battery voltage, check the BLK/YEL
wire between the under-dash fuse/relay box and
rhe lcM.
. lf there is battery voltage, go to step 4.
Turn the ignition switch ON (ll). Check for voltage
between the wire*r and body ground
There should be battery voltage.
. lfthere is no battery voltage, check:
- the ignition coil.
- the wire*1 between the ignition coil and the
tcM.
. lf there is battery voltage, go to step 5
*1: BLU'wire (HITACHI)
WHT/BLU wire (TEC)
Disconnect the EcM/PCM connector A (32P). Check
for continuity on the YEUGRN wire between the
ECM/PCM and the lCM.
There should be continuity.
Check for continuity on the YEUGRN wire to body
ground.
There should be no continuity.
Check for continuity on the BLUl wire between the
test tachometer connector and the ICM
There should be continuitY.
Check for continuity on the BLUl wire to body ground.
There should be no continuity.
lf all the tests are normal, replace the ICM
