Removal
Caution:
Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to prevent airbag and seat belt pretensioner activation.

Inspection

Standard resistance 
If the result is not as specified, replace the switch.
(1) Connect the battery's positive (+) lead to terminal 3 and negative (-) lead to terminal 2.
Then check that the bulb illuminates.
Ok: bulb illuminates.
If the result is not as specified, replace the switch.
Installation

Brake pedal load sensing switch
Traction control switch (for 2wd)Intermediate shaft speed sensor "A"
Description
This sensor detects the rotation speed of the counter gear. By comparing the
counter gear speed signal
(nc) with the direct clutch speed sensor signal (nt), the ecm detects the shift
timing of the gears and
approximately controls the engine torque and hydraulic pressure accord ...
Transmission fluid temperature sensor "A" circuit
Description
The automatic transmission fluid (atf) temperature sensor converts the atf
temperature into a
resistance value which is input into the ecm.
The ecm applies a voltage to the temperature sensor through ecm terminal tho1.
The sensor resistance changes with the atf temperature. ...
Short to b+ in can bus line
Description
There may be a short circuit between the can bus line and +b when there is
resistance between
terminals 6 (canh) and 16 (bat) or terminals 14 (canl) and 16 (bat) of the dlc3.
