NOTE:
• Air t e m p e r a t u r e must be between 59° and 100°F (15°
and 38°C) d u r i n g this procedure.
• After this test, or any subsequent repair, reset the
ECM/PCM t o clear any codes {see page 11-3).
• The battery m u s t be in good condition and fully
charged.
Recommended Procedure:
• Use a starter system tester.
• Connect and operate the equipment in accordance
with the manufacturer's instructions.
Alternate Procedure
1. Hook up the following equipment:
. A m m e t e r , 0 — 400 A
• Voltmeter, 0 ^ 2 0 V (accurate within 0.1 volt)
• Tachometer, 0
1200 r p m
2. Remove the No. 46 (15A) fuse f r o m the under-dash
fuse/relay box.
3. With the shift lever in E or OS {A/T), or the clutch
pedal depressed (M/T), t u r n the ignition switch t o
start (III).
Did the starter
crank the engine
normally?
Y E S - The starting system is O K . B
NO
If the starter will not crank the engine at all, go
to step 4. If it cranks the engine erratically or t o o
slowly, go t o step 7. If it w o n ' t disengage f r o m the
flywheel or torque converter ring gear w h e n y o u
release the key, check f o r the f o l l o w i n g until y o u
find the cause.
• Solenoid plunger and switch malfunction
• Dirty drive gear or d a m a g e d overrunning clutch
Check the battery condition. Check electrical
connections at the battery, the negative battery
cable to body, engine ground cables, and t h e
starter for looseness and corrosion. Then t r y
starting the engine again.
Did the starter
crank the
engine?
Y E S - Repairing the loose connection fixed t h e
problem. The starting system is O K . B
NO
G o t o step 5.
Make sure the transmission is in neutral, then
disconnect the BLK/WHT w i r e (A) f r o m the starter
solenoid (B). Connect a j u m p e r wire f r o m the
battery positive terminal to the solenoid t e r m i n a l .
Did the starter

engine?
Y E S - G o t o step 6.
NO —Remove the starter and repair or replace as
necessary.
6. Check the f o l l o w i n g items in the order listed until
you find the open circuit.
• Check the BLK/WHT wire and connectors
between the driver's under-dash fuse/relay box
and the ignition switch, and between the driver's
under dash fuse/relay box and the starter.
• Check the ignition switch (see page 22-56).
• Check the transmission range switch and
connector (A/T) or the clutch interlock switch (see
page 4-6) and connector(M/T).
• Substitute a known-good starter relay.
