ENGINE MECHANICAL
Before performing any on-vehicle adjustments to fuel or
ignition systems, ensure engine mechanical condition is okay.
VALVE CLEARANCE
NOTE: All engines use hydraulic lifters. No adjustments are
required.
IGNITION TIMING
On all models, ignition timing is controlled by Powertrain
Control Module (PCM). Ignition timing is nonadjustable. DO NOT attempt\
to adjust ignition timing by rotating distributor.
NOTE: On Dakota 3.9L, 5.2L and 5.9L, Durango, Ram Pickup, Ram Van
and Ram Wagon, if distributor is rotated, fuel system
synchronization will be changed. If distributor is removed or
rotated, check fuel system synchronization. See procedures
under FUEL SYSTEM SYNCHRONIZATION under FUEL SYSTEM.

PASSENGER AIR BAG DISARM (PAD) SWITCH
PAD switch is mounted on instrument panel. Switch allows
passenger-side airbag module to be disarmed when rear facing child
safety seat is being used. PAD switch is operated with ignition key.
SYSTEM OPERATION CHECK
Turn ignition on and observe AIR BAG warning light. AIR BAG
warning light should illuminate for 6-8 seconds and then go out,
indicating system is functioning properly. If AIR BAG warning light
either fails to illuminate or illuminates continuously, a system
malfunction exists. Perform self-diagnostics. See DIAGNOSIS & TESTING.
After completing necessary repairs, turn ignition switch to
ON position. Ensure no one is inside vehicle, then connect negative
battery cable. Using DRB, erase stored Diagnostic Trouble Codes (DTC).\
See DIAGNOSIS & TESTING .
SERVICE PRECAUTIONS
These precautions should be observed when working with air
bag systems:
* Disable air bag system before servicing any air bag system
or steering column component. Failure to do this could
result in accidental air bag deployment and possible
personal injury. See DISABLING & ACTIVATING AIR BAG SYSTEM .
* Back-up power supply maintains deployment voltage for about
2 minutes after battery is disconnected. When disabling air
bag system, always wait at least 2 minutes after
disconnecting battery cables to resume procedure.
* After repairs, ensure AIR BAG warning light works
properly and no system faults are indicated. See
SYSTEM OPERATION CHECK .
* Always wear safety glasses when servicing or handling an
air bag.
* All SRS component fasteners are specially coated and are
designed with a specific function. Never replace SRS
component fasteners with other than original equipment parts.
* Air bag module must be stored in its original special
container until used for service. It must be stored in a
clean, dry, place, away from sources of extreme heat, sparks
and high electrical energy.
* When placing a live air bag on a bench or other surface,
always face air bag and trim cover up, away from surface.
This will reduce motion of module if accidentally deployed.
* After deployment, air bag surface may contain deposits of
sodium hydroxide, which irritates skin. Always wear safety
glasses, rubber gloves, and long-sleeved shirt during
clean-up and wash hands using mild soap and water. Follow
correct disposal procedures. See DISPOSAL PROCEDURES.
* Because of critical system operating requirements, DO NOT
attempt to service any air bag components. Corrections are
only made by replacing defective part.
* Electrical sources should never be allowed near inflator on
back of air bag module.
* When carrying a live air bag module, trim cover should be
pointed away from your body to minimize injury in case of
deployment.
* When testing voltage or continuity at Air Bag Control Module

Requested WARM boot or User-Requested COLD boot. If DRB should display
any other error message, record entire display and contact
manufacturer.
2) If DRB does not power-up, check for loose cable
connections or a bad cable. Check vehicle battery voltage (data link
connector terminal No. 16). A minimum of 11 volts is required to
adequately power DRB.
3) If all connections are proper between DRB and vehicle or
other devices, and vehicle battery is fully charged, an inoperative
DRB may be result of faulty cable or vehicle wiring.
ENTERING ON-BOARD DIAGNOSTICS
1) Before entering on-board diagnostics, refer to
PRETEST INSPECTION & DIAGNOSTIC PROCEDURE . Connect DRB to data link
connector. Data link connector (DLC) is located under left side of
instrument panel, left of steering column.
NOTE: Read active DTCs with PAD switch in both ON and OFF
positions. Always turn ignition off before changing PAD
switch positions,
2) Turn ignition switch to ON position. Exit vehicle with
DRB. Using DRB, read and record active Diagnostic Trouble Code (DTC)
data. Read and record stored DTC data. If any DTCs (fault messages)
exist, perform appropriate test.
3) If PAD switch OFF indicator fails to illuminate when in
the OFF position, go to PAD SWITCH INDICATOR PROBLEMS . If PAD switch
OFF indicator illuminates when switch is in ON position or key
cylinder does not operate, replace PAD switch.
4) Air Bag Control Module (ACM) may report any of the
following DTCs or fault messages. If the following active or stored
codes are reported by DRB, replace ACM. See
