Toyota RAV4 (XA40) 2013-2018 Service Manual: Vehicle speed signal error (test mode dtc)
Description
The tire pressure warning ecu receives a speed signal from the combination meter. This dtc is stored upon entering test mode, and cleared when a vehicle speed signal of 12 mph (20 km/h) is detected for 3 seconds or more. The dtc is output only in test mode.

Inspection procedure
Notice:
It is necessary to register an id code after replacing the tire pressure warning valve and transmitter and/or the tire pressure warning ecu (see page tw-9).
- Read value of intelligent tester (vehicle speed)
- Check the data list for proper functioning of the vehicle speed signal.
Ok: indicates actual speed.
- Check wire harness (ecu - meter)
- Disconnect the e56 ecu connector.
- Disconnect the e19 meter connector.
- Measure the resistance of the wire harness side connectors.
Standard resistance 
- Check tire pressure warning ecu
- Measure the voltage of the connector.
Standard voltage 
Hint:
As the vehicle speed (wheel revolution speed) increases, a cycle of the waveform narrows.
