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.
Wiring diagram
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.

Tire pressure warning light circuit
Description
If the tire pressure warning ecu detects trouble, the tire pressure warning
light turns on and tire pressure
monitor is canceled at the same time. At this time, the ecu records a dtc i ...

RCTA function
â– Operation of the RCTA
function
The RCTA function uses rear
side radar sensors to detect
vehicles approaching from the right or left at the rear of the
vehicle and alerts the driver of
the presence of such vehicles
by flashing the outside rear view
mirror indicators and sounding a
buzzer.

Data list / active test
Active test
Hint:
Performing the intelligent tester active test allows
relay, vsv, actuator and other items to be operated
without removing any parts. Performing the active
test early in troubleshooting is one way to save time.
The data list can be displayed during the active
test.

Ecm communication circuit malfunction
Description
The circuit is used to send trc and vsc control information from the skid
control ecu to the ecm, and
engine control information from the ecm to the skid control ecu.
Inspection procedure
Hint:
Check that the part numbers of the installed ecm and skid control ecu are
cor ...
