-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,
