-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.

Interlock System
Control Unit Input Test
1. Disconnect the 8P connector from the interlock con-trol unit.
2. Inspect the connector and socket terminals to besure they are all making good contact.. lf the terminals are bent, loose or corroded, repairthem as necessary, and recheck the system.. lf the terminals look OK, make the followinginput tests at the connector.- lf a test indicates a problem, find and correctthe cause, then recheck the system.- lf all the input tests prove OK, substitute aknown-good control unit, and recheck the sys-tem. lf the check is OK, the control unit mustbe faulty; replace it.
NOTE: lf the shift lock solenoid clicks when theignition switch is turned ON {ll) and you step on thebrake pedal (with the shift lever in E), the shift locksystem is electronically normal; if the shift leve.cannot be shifted from E], test the Aff gear position
switch, park pin switch, and see section 14.
