If starter is noisy, the cause could be bent or damaged gear tooth chamfers on ring gear. This cannot be seen
with starter installed in vehicle. Activate starter without switching ignition on. Metallic noise should not be
heard. If noise is heard, replace ring gear.

PRELIMINARY INSPECTION

Verify customer complaint by operating system. Visually inspect for obvious signs of mechanical and electrical
damage. Check generator belt tension and condition. Ensure that battery voltage is within specifications. Inspect
for blown fuses and damaged relays. For fuse and/or relay identification, see WIRING DIAGRAMS .

WARNING:

Vehicles are equipped with air bag supplemental restraint system. Before
attempting any repairs involving steering column, instrument panel or
related components, see SERVICE PRECAUTIONS (or AIR BAG SAFETY
PRECAUTIONS) and DISABLING & ACTIVATING AIR BAG SYSTEM in
appropriate AIR BAG RESTRAINT SYSTEMS article.

NOTE:

When the battery is disconnected, vehicle computer and memory system may
lose data. Driveability problems may exist until computer systems have
completed a relearn cycle. Radio will not operate until coded. Obtain code card
from customer.

Verify ground connection integrity between engine, body, battery and generator. Check for damaged wiring
harnesses and/or switches. Check for a broken or partially broken wire inside insulation, which could cause
system malfunction but prove good in a continuity/voltage check with system disconnected. Ensure any
aftermarket electronic equipment is properly installed. If fault is found, repair as necessary. If no fault is found,
check for conditions that might cause an intermittent situation.
