Toyota RAV4 (XA40) 2013-2018 Service Manual: Receiver error

Description

Wiring diagram

Inspection procedure

Notice:

It is necessary to register an id code after replacing the tire pressure warning valve abd transmitter and/or the tire pressure warning ecu (see page tw-9).

Hint:

Set the tire pressure to the specified value.

Standard pressure: 220 kpa (2.2 Kgf/cm2, 32 psi)

1. Check tire pressure warning ecu

1. Measure the voltage of the connector.

Standard voltage

2. Check wire harness (ecu - receiver)

1. Disconnect the e56 ecu connector.
2. Disconnect the l20 receiver connector.
3. Measure the resistance of the wire harness side connectors.

Standard resistance

3. Replace tire pressure warning antenna and receiver

4. Check dtc

1. Check for dtc (see page tw-20).

Ok: dtc is not output.

Hint:

• It is necessary to register an id when replacing the tire pressure warning ecu (see page tw-9).
• Read id on the data list before removing the tire pressure warning ecu. Register the id in the new tire pressure warning ecu.

End

15. Check wire harness (ecu - receiver)

1. Disconnect the e56 ecu connector.
