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)
- Check tire pressure warning ecu
- Measure the voltage of the connector.
Standard voltage 
- Check wire harness (ecu - receiver)
- Disconnect the e56 ecu connector.
- Disconnect the l20 receiver connector.
- Measure the resistance of the wire harness side connectors.
Standard resistance 
- Replace tire pressure warning antenna and receiver
- Check dtc
- 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.
