Inspection Procedure

WARNING: This page is about a different car, the 2006 Toyota Land Cruiser. However, it is still accessible from the selected car via links, so may be relevant.

HINT:

Using the intelligent tester's DATA LIST allows switch, sensor, actuator and other item values to be read without removing any parts. Reading the DATA LIST early in troubleshooting is one way to save time.

NOTE: In DATA LIST DETAIL , the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.

Warm up the engine.
Turn the ignition switch OFF.
Connect the intelligent tester to the CAN VIM. Then connect the CAN VIM to the DLC3.
Turn the ignition switch ON.
Turn the intelligent tester ON.
Enter the following menus: DIAGNOSIS / ENHANCED OBD II / DATA LIST.

Follow the instructions on the tester and read the DATA LIST.

DATA LIST DETAIL

Item	Measurement Item/Range (Display)	Normal Condition	Diagnostic Note
SPD (SP2)	Output shaft speed/Min.: 0 km/h (0 mph) Max.: 255 km/h (158 mph)	Vehicle stopped: 0 km/h (0 mph) (output shaft speed is equal to vehicle speed)	-

HINT:

SPD (SP2) is always 0 while driving: Open or short in the sensor or circuit.
SPD (SP2) value displayed on the tester is much lower than the actual vehicle speed: Sensor trouble, improper installation, or intermittent connection trouble of the circuit.

INSPECT SPEED SENSOR INSTALLATION
1. Check the speed sensor SP2 installation.
  OK: Installation bolt is tightened properly and there is no clearance between the sensor and transmission case.
NG: SECURELY INSTALL SENSOR OR REPLACE SENSOR
