WIRING DIAGRAM
INSPECTION PROCEDURE
NOTICE:
- When replacing the master cylinder solenoid, perform zero point calibration
- Check the speed sensor signal in test mode after clearing or replacement
PROCEDURE
CHECK HARNESS AND CONNECTOR (MOMENTARY INTERRUPTION)
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(c) Turn the tester on.
(d) Using the Techstream, check for any momentary interruption in the wire harness and connector of the speed sensor.
Select the following menu items: Chassis / ABS/VSC/TRAC/ Data List

Normal Condition
Diagnostic Note
RR Speed Open
RR speed sensor open detection: OPN_DET or NORMAL
OPN_DET: Momentary interruption
NORMAL: Normal
RL Speed Open
RL speed sensor open detection: OPN_DET or NORMAL
OPN_DET: Momentary interruption
NORMAL: Normal
There are no momentary interruptions.
HINT:
Perform the above inspection before removing the sensor and connector.
CHECK AND REPLACE HARNESS OR CONNECTOR
READ VALUE USING DATA LIST
(a) Connect the Techstream to the DLC3.
(b) Start the engine and drive the vehicle.

Similar to speed indicated on speedometer
RR Wheel Speed
Wheel speed sensor (RL) reading : min.: 0 MPH (0 km/h), max.: 202 MPH (326 km/h)
Actual wheel speed
Similar to speed indicated on speedometer
(e) Check that there is no significant difference between the speed value displayed on the Techstream and the speed value displayed on the speedometer when driving the vehicle.
There is no significant difference in the displayed speed values.
HINT:
There is a tolerance of +- 10% in the speedometer indication.
