Toyota RAV4 (XA40) 2013-2018 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.

  1. Disconnect the e56 ecu connector.
  2. Disconnect the e19 meter connector.
  3. Measure the resistance of the wire harness side connectors.

Standard resistance



  1. Check tire pressure warning ecu

Hint:

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