light is still on, repair warning light circuit or AB circuit leading to DLC. See Fig. 12
.
AIR BAG WARNING LIGHT INTERMITTENT
If air bag warning light comes on intermittently, perform the following tests to simulate driving conditions:
Wiggle-test wiring harness.
Using a hair dryer, apply heat to components.
Spray water onto entire vehicle (not directly onto electrical components) to simulate humidity.
If problem cannot be found, replace all components including wiring harness.
CODE(S) NOT DISPLAYED
1. Turn ignition switch from LOCK to ACC or ON position. If air bag warning light does not come on,
repair air bag warning light circuit. If air bag warning light comes on, go to next step.
2. Turn ignition to ACC or ON. Measure voltage between terminals Tc and E1 of DLC. See Fig. 12
. If
battery voltage is present, go to step 4). If battery voltage is not present go to next step.
3. Measure voltage between body ground and terminal Tc of DLC. If battery voltage is present, repair
harness between body ground and terminal E1 of DLC. If battery voltage is not present, go to next step.
4. Turn ignition to LOCK. Disconnect negative battery cable. wait at least 90 seconds. Disconnect air bag
sensor assembly connector. Connect a jumper wire between body ground and terminal Tc from back side.
See Fig. 13
. If air bag warning light does not come on, replace air bag sensor. If air bag warning light
comes on, check wiring harness between air bag sensor and DLC.
CODE(S) CONTINUOUSLY DISPLAYED

AIR BAG RESTRAINT SYSTEM
1999 Toyota
DESCRIPTION & OPERATION
Supplemental Restraint System (SRS), also known as air bag system, is designed to provide increased accident
protection for driver and passenger by deploying air bags in a front-end collision. The air bag system is
designed to be used in conjunction with 3-point safety belts.
The air bag system includes the following components: driver-side air bag module (steering wheel pad),
passenger-side air bag module, spiral cable, AIR BAG warning light, air bag sensor assembly, right and left
front air bag sensors, right and left front seat belt pretensioners and associated wiring harnesses. See Fig. 1
. WARNING:To avoid injury from accidental air bag deployment, read and carefully
follow all WARNINGS and SERVICE PRECAUTIONS
.

may allow air bag to deploy until 90 seconds after disconnecting negative battery cable.
If vehicle was in a minor collision but air bags did not deploy, inspect all system components for any sign
of damage, and replace as necessary.
Never use air bag system components from another vehicle. Replace air bag system components with new
parts.
Remove air bag sensor assembly if repairing the vehicle requires impacting (shocking) the vehicle.
Air bag sensor assembly contains mercury. After replacement, DO NOT destroy old part. When
scrapping vehicle or replacing air bag sensor assembly, remove air bag sensor assembly and dispose of it
as toxic waste.
Never disassemble and repair air bag sensor assembly, front air bag sensors, passenger-side or driver-side
air bag modules or seat belt pretensioners.
Replace dropped, cracked, dented or otherwise damaged components.
DO NOT expose air bag sensor assembly, front air bag sensors or air bag modules directly to heat or
flame.
When diagnosing electrical circuits, use a volt/ohm meter with high impedance (10,000 ohms minimum).
Information labels are attached to air bag components. Follow all notices on labels.
After work on air bag system is complete, check AIR BAG warning light to ensure system is functioning
properly. See SYSTEM OPERATION CHECK
.
Always wear safety glasses when servicing or handling an air bag.
When placing a live air bag on a bench or other surface, always face air bag and trim cover up and away
from surface. This will reduce motion of module if it is 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. After clean-up, wash hands
using mild soap and water.
Carry a live air bag module with trim cover (air bag) pointed away from your body to minimize injury in
case accidental deployment.
If air bag system is not fully functional for any reason, vehicle should not be driven until system is
repaired and again becomes operational. DO NOT remove bulbs, modules, sensors or other components,
or in any way disable system from operating normally. If air bag system is not functional, park vehicle
until it is repaired and functions properly.
ADJUSTMENTS
SPIRAL CABLE
Ensure front wheels are in straight-ahead position. Turn spiral cable counterclockwise until it becomes difficult
to turn. Turn spiral cable clockwise about 2 1/2 turns to align match marks. See Fig. 2
. Install steering wheel.
