Toyota RAV4 Service Manual: Vehicle speed signal error (test mode dtc)

Toyota RAV4. 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).

  1. Read value of intelligent tester (vehicle speed)

  1. Check the data list for proper functioning of the vehicle speed signal.

Hint:

As the vehicle speed (wheel revolution speed) increases, a cycle of the waveform narrows.
