ground clearance 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 .

4. Remove front (radiator side) engine mount shock absorber-to-lower frame assembly bolts. Remove front
(radiator side) engine mount-to-lower frame assembly bolts/nuts.
5. Remove front (radiator side) exhaust manifold brace from rear of exhaust manifolds. Brace fits between
rear of exhaust manifold and front of transaxle.
6. Remove the 5 upper transaxle-to-cylinder block bolts. Support engine with hoist. Steering gear assembly
must be supported in place during transaxle removal. Secure steering gear assembly to the engine hoist
using an attaching strap placed at each end of steering gear assembly.
7. Remove front wheels. Remove engine undercover. Remove front exhaust pipe located between exhaust
manifolds and rear exhaust pipe. Drain transaxle fluid. Remove axle shafts from transaxle. See FWD
AXLE SHAFTS article in DRIVE AXLES.
8. Disconnect shift control cable from mounting bracket. Remove rear (firewall side) engine mount-to-lower
frame assembly bolts/nuts. Remove transaxle mount-to-transaxle bolts/nuts at driver's side end of
transaxle.
9. Remove stabilizer bar mount bracket-to-lower frame assembly bolts. Remove steering gear assembly-to-
lower frame assembly bolts/nuts. Support lower frame assembly with floor jack. Lower frame assembly is
located below the engine and transaxle.
10. Disconnect power steering reservoir pipe mounting brackets from lower frame assembly. Remove lower
frame assembly mounting brackets. Lower frame assembly mounting brackets are located on the front
and rear of lower frame assembly attaching the lower frame assembly to the body. Remove lower frame
assembly.
11. Support transaxle with transmission jack. Remove torque converter bracket and cover bolts and nuts from
front of transaxle. Remove torque converter bolts. Remove remaining transaxle-to-cylinder block bolts.
Lower transaxle from vehicle.
Installation
NOTE: Wiper/washer components and output front cowl top panel must be
removed for clearance during transaxle removal and installation.

Inspection
1. Inspect cylinder head warpage at cylinder block, exhaust manifold and intake manifold surfaces. Replace
cylinder head if warpage exceeds specification. See CYLINDER HEAD
table under ENGINE
SPECIFICATIONS.
2. Inspect cylinder block deck surface for warpage. Replace cylinder block if deck surface warpage exceeds
specification. See CYLINDER BLOCK
table under ENGINE SPECIFICATIONS.
3. Inspect intake and exhaust manifold machined surfaces for warpage. Replace component if warpage
exceeds .0118" (.300 mm). Inspect camshaft and components. See CAMSHAFT
.
4. Measure valve lifter diameter and bore diameter. Ensure oil clearance is within specification. Replace
components if not within specification. See VALVE LIFTERS
table under ENGINE
SPECIFICATIONS.
Installation
1. Apply adhesive to 2 or 3 threads of oil pressure switch, and install switch. Install NEW insulator at
bottom of fuel injector and NEW grommet on top of fuel injector. Coat NEW "O" rings with gasoline and
install on fuel injector.
2. Install 2 spacers on cylinder head. Install fuel injectors on cylinder head. Install fuel delivery pipe on fuel
injectors. Using twisting motion, push fuel injectors into fuel delivery pipe.
3. Install and slightly tighten fuel delivery pipe-to-cylinder head bolts. Ensure all fuel injectors rotate
smoothly. If fuel injector fails to rotate smoothly, check for improperly installed or damaged "O" rings.
4. Position electrical connector on fuel injector facing toward top of engine. Tighten fuel delivery pipe-to-
cylinder head bolts to specification. See TORQUE SPECIFICATIONS
.
5. Using NEW gasket, install intake manifold. Install and tighten bolts/nuts to specification. See TORQUE
