2001-04 STARTING & CHARGING SYSTEMS Starters - 163 Chassis 
MODEL IDENTIFICATION  
MODEL IDENTIFICATION    
DESCRIPTION  
Starter is a brush-type, series-wound el  ectric motor with an overrunning clutch. Field frame contains field coils  
and is enclosed by commutator/drive bushing end frame,   which carries pole shoes. A splined armature shaft  
carries drive assembly.  
TROUBLE SHOOTING 
BASIC TROUBLESHOOTING 
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 ve  hicle. Activate starter without switching ignition on. Me tallic noise should not be  
heard. If noise is he  ard, 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 steer  ing column, instrument panel or  
related components, see SERVICE   PRECAUTIONS (or AIR BAG SAFETY  
PRECAUTIONS) and DISABLING &   ACTIVATING AIR BAG SYSTEM in  
appropriate AIR BAG REST  RAINT SYSTEMS article. 
NOTE: When the battery is di  sconnected, 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. 
NOTE: The following table identifies mo  dels applicable to this article.

Verify ground connection integrity between engine, body,  battery and generator. Check for damaged wiring  
harnesses and/or switches. Check fo  r a broken or partially broken wire inside insulation, which could cause  
system malfunction but prove good in a continuity/vol  tage check with system disconnected. Ensure any  
aftermarket electronic e  quipment is properly installed.  If fault is found, repair as necessary. If no fault is found,  
check for conditions that might   cause an intermittent situation.  
SERVICE PRECAUTIONS 
BATTERY DISCONNECT/CONNECT 
Disconnect/Connect Procedures 
1. Turn ignition off. Open engine hood. After opening ve  hicle wait at least 4 minutes before disconnecting  
battery or alarm wi  ll be triggered.   
2. Disconnect negative battery cable (1) and insulate   cable lug to prevent unwanted contact with ground  
point (W16/4). See   Fig. 1
 .   
3. To connect, reverse disconnect procedur  e. Tighten nut (5) to specification. See TORQUE 
SPECIFICATIONS .   
4. Perform basic programming, read Diagnostic Tr  ouble Code (DTC) memory and erase DTCs from  
memory. See   BASIC PROGRAMMING
 and RETRIEVING & ERASING DIAGNOSTIC 
TROUBLE CODES .   
NOTE: Numbers and letters in text refe 
r to numbers and letters in figures.

Coding radio 
Hi-Line Premium With Bose(R) 
1. Turn ignition on. CODE will appear on radio displa  y. Enter first code number with station button. For  
example, station button 1 is number 1.   
2. After entering first number, CODE will disappear   and first number entered will appear followed by 4  
dashes. The next character to be entered flashes.   Repeat procedure until all numbers are entered.   
3. If an input error has occurred it can be corrected at   this time by reentering the complete correct code.   
4. Confirm entry of correct   code with < or > button.   
5. If an incorrect code number has been entered, CODE   appears again on display. If an incorrect code is  
entered 3 times, WAIT appears on display and ra  dio locks up for approximately 10 minutes. If an  
incorrect code is entered 3 times   again, lock time increases to 60 mi nutes. Radio must remain switched on  
during lock up time.
