Toyota RAV4 (XA40) 2013-2018 Service Manual: Brake switch "b" circuit high
Description
The purpose of this circuit is to prevent the engine from stalling while driving in the lock-up condition when the brakes are suddenly applied.
When the brake pedal is depressed, this switch sends a signal to the ecm. Then the ecm cancels the operation of the lock-up clutch while braking is in progress.
Monitor description
This dtc indicates that the stop light switch remains on. When the stop light switch remains on during go and stop driving, the ecm interprets this as a fault in the stop light switch. Then the mil illuminates and the ecm stores the dtc. The vehicle must go (30 km/h (18.63 Mph) or more) and stop (less than 3 km/h (1.86 Mph)) 5 times for 2 driving cycles in order for the dtc to be output.

Inspection procedure
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.
Notice:
In the table below, 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.
- Inspect stop light switch
- Remove the a3 stop light switch.
- Measure the resistance of the switch.
Standard resistance 
- Check wire harness (ecm - battery)
- Measure the voltage of the wire harness side connector.
Standard voltage 
Vin not programmed or mismatch - ecm / pcm

Pressure control solenoid "A " performance (shift solenoid valve sl1)
Description
The ecm uses signals from the vehicle speed sensor to detect the actual gear
position (1st, 2nd, 3rd or
o/d gear).
Then the ecm compares the actual gear with the shift schedule in the ecm memory
to detect mechanical
problems of the shift solenoid valves, valve body or automatic ...
