Sensor Output Value Inspection
CAUTION:
Resistance inspection using other testers may cause damage to the ABS wheel-speed sensor internal circuit. Be sure to use the M-MDS to inspect the ABS wheel-speed sensor.
1. Switch the ignition to off.
2. Connect the M-MDS to the DLC-2.
3. Select the following PIDs using the M-MDS:
WSPD_SEN_LF (LF wheel-speed sensor)
WSPD_SEN_RF (RF wheel-speed sensor)
4. Start the engine and drive the vehicle.
5. Verify that the display of the M-MDS shows the same value as the speedometer.
If there is any malfunction, replace the ABS wheel-speed sensor.
Installation Visual Inspection
1. Inspect for the following:
If there is any malfunction, replace the part.
a. Excessive play of the ABS wheel-speed sensor
b. Deformation of the ABS wheel-speed sensor
c. Deformation or damage of the ABS sensor rotor
Clearance Inspection
Preparation prior to inspection
1. Remove the ABS wheel-speed sensor..
2. Remove the wheel hub and steering knuckle as a single unit..
3. Install the ABS wheel-speed sensor to the removed wheel hub, steering knuckle component, and tighten to the specified torque.
8—10 N·m {82—101 kgf·cm, 71—88 in·lbf}
Clearance Inspection
1. Measure the gap between the ABS sensor rotor and ABS wheel-speed sensor using a feeler gauge.
If not within the specification, verify the following items and repair or replace if necessary.
Is there deformation or damage to the ABS sensor rotor?
Is there deformation or damage to the ABS wheel speed sensor?
Is there foreign material adhering?
0.87—1.53 mm {0.035—0.060 in}
Servicing after inspection
1. Remove the ABS wheel-speed sensor from the wheel hub, steering knuckle component.
2. Install the wheel hub, steering knuckle component..
3. Install the ABS wheel-speed sensor..
4. Inspect the front wheel alignment..
Electric Variable Valve Timing Actuator
Purpose, Function
The electric variable valve timing actuator changes the phases of the intake
camshaft relative to the crankshaft. As a result, the open/close period of the
intake valve is changed, optimized valve timing in accordance with driving conditions
is realized, output is i ...
Seat Belt Warning Light
Purpose
The seat belt warning light warns the driver that a seat belt is not fastened.
Function
The instrument cluster flashes/illuminates the seat belt warning light based
on the following CAN signals:
Vehicle speed signal sent from PCM
Driver/passenge ...
Crankshaft Position (CKP) Sensor Inspection
Visual Inspection
CAUTION:
When foreign material such as an iron chip is on the CKP sensor, it can cause
abnormal output from the sensor because of flux turbulence and adversely affect
the engine control. Be sure there is no foreign material on the CKP sensor when
replacing.
