wheel TOYOTA RAV4 1996 Service User Guide

The air bag sensor, which deploys air bags, contains a back-up power supply, safing sensor and diagnostic code
memory. Spiral cable (clockspring) maintains a complete circuit to the steering wheel pad.
SYSTEM OPERATION CHECK
Turn ignition switch to ACC or ON position. Air bag warning light in instrument cluster should come on for
about 6 seconds and then go out. If light does not respond as specified, SRS is malfunctioning and needs repair.
See DIAGNOSIS
.
SERVICE PRECAUTIONS
Observe the following precautions when working on SRS:
Before servicing any SRS or steering column component, disable SRS. See DISABLING &
ACTIVATING AIR BAG SYSTEM . Failure to disable system could result in accidental air bag
deployment and personal injury.
When diagnosing SRS, always check for diagnostic codes before disconnecting battery.
After ignition switch is turned to LOCK position and negative battery cable is disconnected, wait at least
90 seconds before working on SRS. SRS is equipped with a back-up power source that may allow air bag
to deploy within 90 seconds of disconnecting negative battery cable.
In a minor collision in which air bags do not deploy, steering wheel pad must be inspected.
NEVER use air bag parts from another vehicle. Replace air bag parts with new parts.
Air bag sensor assembly contains mercury. After replacement, DO NOT destroy the old part. When
scrapping vehicle or replacing air bag sensor assembly, remove air bag sensor assembly and dispose of as
toxic waste.
Never disassemble or repair system components. Replace cracked, dented or otherwise damaged system
components.
Remove air bag sensor if shocks are likely to be applied to the sensor during repairs.
When diagnosing electrical circuits, use a Digital Volt/Ohmmeter (DVOM) with high impedance (10,000
ohms minimum).
Information labels are attached to air bag components. Follow all notices on labels.
After servicing SRS, 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, 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. During
clean-up, always wear safety glasses, rubber gloves and long-sleeved shirt. After clean-up, wash hands
using mild soap and water.
When carrying a live air bag module, trim cover must be pointed away from your body to minimize
injury in case of accidental deployment.
If SRS is not fully functional for any reason, vehicle should not be driven until system is repaired and
a
gain becomes operational. DO NOTremove bulbs, modules, sensors or other components or in any way

DISPOSAL PROCEDURES
WARNING:Undeployed air bags contain substances that can cause illness or injury if
improperly handled. Disposing of undeployed components may violate
federal, state and/or local laws. If scrapping vehicle, components must be
deployed while still mounted in vehicle. DO NOT deploy components
inside vehicle unless vehicle is to be scrapped. Wear gloves and safety

DEPLOYING AIR BAG
On-Vehicle Deployment (Scrapped Vehicles Only)
1. Before proceeding, follow service precautions. See SERVICE PRECAUTIONS . Turn ignition switch
to LOCK position. Disconnect and shield negative battery cable. Wait at least 90 seconds before working
on system.
2. Disable air bag system. See DISABLING & ACTIVATING AIR BAG SYSTEM
. Connect
Deployment Tool (09082-00700) to air bag connector. Position deployment tool at least 33 feet from
front of vehicle.
3. Close all doors and windows of vehicle. Connect deployment tool Red clip to positive battery terminal
and Black clip to negative battery terminal. Ensure no one is within 33 feet of vehicle. Press deployment
tool activation switch to deploy air bag. Because of heat, DO NOT touch air bag for at least 30 minutes
after deployment.
Off-Vehicle Deployment (Driver-Side)
1. Before proceeding, see SERVICE PRECAUTIONS . Disable SRS. See DISABLING &
ACTIVATING AIR BAG SYSTEM . Remove steering wheel pad from vehicle. See STEERING
WHEEL PAD & SPIRAL CABLE under REMOVAL & INSTALLATION.
2. Remove connector on steering wheel pad rear surface and install 2.236" (6.0 mm) bolts (1.38" 35 mm
long) with washers in steering wheel pad. Bolts should have a pitch of .039" (1.0 mm). Tighten bolts by
hand until they become difficult to turn. DO NOT overtighten bolts. Obtain a wheel and tire assembly.
Using a service-purpose wire harness, tie down the steering wheel pad to the wheel and tire assembly.
3. Wrap heavy-gauge 3-wire harness around bolts at least twice. See Fig. 4
. Ensure no slack is present in
wire. If slack is present, or if wire is not strong enough, steering wheel pad may become loose due to
shock when air ba
g is deployed. glasses when handling components. Wrap deployed components in a
sturdy plastic bag. Dispose of components like any other part.
WARNING:When attaching air bag assembly to tire, ensure wire is tight. If slack
is present, or if wire is not strong enough, air bag assembly may
become loose due to shock when air bag is deployed.
