torque TOYOTA RAV4 1996 Service Repair Manual

1. Disconnect front speed sensor connector. Measure resistance between speed sensor connector terminals.
Resistance should be 1.4-1.8 k/ohms. Measure resistance between ground and each speed sensor
connector terminal. Resistance should be one megohm or more. If resistance is as specified, go to step 3 .
If resistance is not as specified, replace speed sensor.
2. Disconnect rear speed sensor connector. Measure resistance between speed sensor connector terminals.
Resistance should be 1.28-1.48 k/ohms. Measure resistance between ground and each speed sensor
connector terminal. Resistance should be one megohm or more. If resistance is as specified, go to next
step. If resistance is not as specified, replace speed sensor.
3. Check for open or short circuit in wiring harness between affected speed sensor and ABS ECU. See
WIRING DIAGRAMS
. Repair as necessary. If wiring harness is okay, go to next step.
4. Check speed sensor installation. Ensure mounting bolt is tightened to specification. See TORQUE
SPECIFICATIONS . Ensure zero clearance exists between sensor and front steering knuckle or rear axle
carrier. Replace speed sensor if necessary. If speed sensor installation is okay, check speed sensor signal.
See SPEED SENSOR DIAGNOSTICS
under DIAGNOSIS & TESTING. If signal is normal, go to next
step.
5. If oscilloscope is available, check speed sensor signal wave form. Remove ABS ECU. Do not disconnect
electrical connectors. Connect oscilloscope between GND terminal and terminals FR+, FL+, RR+ and
RL+ at ABS ECU connector. See Fig. 3
. Drive vehicle at 19 MPH and observe signal wave form. Signal
should be smooth and consistent without any irregular wave forms. If wave form is smooth and
consistent, replace ABS ECU. If wave form is not smooth and consistent, go to next step.
6. Check speed sensor rotor for missing teeth or damage. Check sensor tip for scratches, damage or foreign
objects. Replace components as necessary. If rotor and sensor are okay, replace ABS ECU.
DTC 37: TIRES OF DIFFERENT SIZE (2WD MODELS ONLY)
DTC Detecting Condition
Detection of the following condition may set DTC 37:
Driving vehicle at speed of more than 12 MPH for more than 20 seconds with one or 2 tires of different
sizes, 3 different times continuously will set DTC 37.
Diagnostic Procedure
Ensure vehicle tires are all the same size and correct size for vehicle. Replace tires as necessary. If tire size is
okay, replace ABS ECU.
DTC 41: LOW BATTERY VOLTAGE
Circuit Description
Circuit is power source for ABS ECU, which includes actuator. If malfunction occurs in power source circuit,
ABS ECU cuts off current to ABS control relay and prohibits ABS control. DEFINITIONS
under DIAGNOSIS & TESTING. For front speed sensor diagnosis,
start at step 1 . For rear speed sensor, start at step 2 .
