jump start terminals TOYOTA RAV4 1996 Service Repair Manual

If cause of faulty operation cannot be located with basic diagnosis, ABS electronic control system must be
checked. See DIAGNOSIS & TESTING
.
When ignition is turned on, ABS warning light should come on, then go out after 3 seconds. If ABS warning
light does not operate as specified, go to ABS WARNING LIGHT under DIAGNOSIS & TESTING
.
DIAGNOSIS & TESTING
RETRIEVING DIAGNOSTIC TROUBLE CODES
ABS Warning Light Diagnostics
1. Ensure battery voltage is 12 volts. Turn ignition switch to ON position. ABS warning light should
illuminate, then go out after 3 seconds. If ABS warning light does not illuminate, check fuse, bulb, and
wiring harness. See ABS WARNING LIGHT
.
2. Remove short pin from DLC1. DLC1 is located in engine compartment, on left side of engine. See Fig.
2 . Using a jumper wire, jumper DLC1 terminals Tc and E1 . If a malfunction is detected, ABS warning
light will begin to flash a 2-digit Diagnostic Trouble Code (DTC). First number of blinks will equal first
digit in DTC. After a 1.5-second pause, second number of blinks will equal second digit in DTC.
3. If 2 or more DTCs are stored, there will be a 2.5-second pause between each DTC. After all DTCs are
flashed, there will be a 4 second pause and all DTCs will repeat. If ABS system is functioning properly,
ABS warning light will blink 2 times per second. For code definitions, see DTC DEFINITIONS
. For
DTC diagnosis, see DIAGNOSTIC TESTS
.
4. After replacing or repairing components, clear DTCs. If battery cables were disconnected during repairs,
all DTCs will be erased. If battery cables were not disconnected during repairs, see CLEARING DTCS
.
DTC DEFINITIONS NOTE: DO NOT start engine when retrieving DTCs.
NOTE: Speed sensor diagnostics and code retrieval use different DLC1 terminals to
access DTCs. If a speed sensor or speed sensor circuit problem is suspected,
see SPEED SENSOR DIAGNOSTICS

CLEARING CODES
1. At DLC, connect a jumper wire to terminal Tc, and another jumper wire to terminal AB. See Fig. 12
.
Turn ignition switch to ACC or ON position. Wait about 6 seconds.
2. Starting with terminal Tc, apply body ground alternately to terminal Tc and terminal AB twice each, in
cycles of 1/2 to 1 1/2 seconds. Finally, keep applying body ground to terminal Tc until air bag warning
light flashes quickly, indicating codes are cleared.

WARNING:Failure to follow air bag service precautions may result in air bag
deployment and personal injury. See SERVICE PRECAUTIONS
. After
component replacement, perform system operational check to ensure
proper system operation. See SYSTEM OPERATION CHECK
.
CAUTION: Ensure ignition switch is in LOCK position before disconnecting or
connecting negative battery cable. If ignition switch is in ACC or ON
position when negative battery cable is disconnected or connected, center

Using Jumper Wire
1. Use 2 jumper wires. Connect one end of first jumper wire to DLC1 terminal Tc and one end of second
jumper wire to DLC1 terminal AB. See Fig. 14
. Turn ignition switch to ACC or ON position. Wait about
6 seconds.
2. Starting with jumper wire connected to terminal Tc, apply body ground alternately to terminal Tc and
terminal AB twice each, in cycles of 1/2 to 1 1/2 seconds (sequence is: Tc, AB, Tc, AB). Finally, keep

NOTE: When alternately grounding terminals Tc and AB, release ground from one
terminal and immediately ground the other terminal within 0.2 second. If
time interval exceeds 0.2 second, DTCs will not be cleared.
