Toyota RAV4 (XA40) 2013-2018 Service Manual: Stop light switch circuit
Description
While driving with the cruise control, if the ecm detects that the brake pedal is depressed, the cruise control operation will be canceled. The stop light switch sends brake pedal status signals to the ecm.
When the brake pedal is not depressed, terminal st1- is equal to the positive (+) battery voltage and terminal stp is below 1 v. When the brake pedal is depressed, the ecm cancels cruise control operation.
The ecm outputs this dtc when the voltage of terminals st1- and stp are both below 1 v for 0.5 Seconds or more at the same time. The fail-safe function operates to enable normal driving even if there is a malfunction in the stop light signal circuit.
Hint:
*: W/ vehicle stability control system

Inspection procedure
- Read value of intelligent tester (stop light switch)
- Check the data list for proper functioning of the stop light switch.
Ok: display changes according to brake pedal operation described in above table.
- Inspect fuse (stop, ign, ig2)
- Remove the stop and ign fuses from the instrument panel junction block.
- Remove the ig2 fuse from the engine room no. 1 Relay block.
- Measure the resistance of the fuses.
Standard resistance:
below 1 
- Inspect ig2 relay
- Remove the ig2 relay from the instrument panel junction block.
- Measure the resistance of the relay.
Standard resistance 
- Inspect stop light switch
- Remove the stop light switch.
- Measure the resistance of the switch.
