Toyota RAV4 Service Manual: 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 in memory.
Connect terminals tc and cg of the dlc3 to make the tire pressure warning light blink and output the dtc.

Inspection procedure
Notice:
It is necessary to register an id code after replacing the tire pressure monitor valve and/or the tire pressure warning ecu (see page tw-9).
- Inspect fuse (gauge)
- Remove the gauge fuse from the instrument panel junction block.
- Measure the resistance of the fuse.
Standard resistance:
below 1 
- Check tire pressure warning light circuit
- Disconnect the e56 ecu connector.
- Using a service wire, connect e56-6 (ind) on the wire harness side and body ground.
- Turn the ignition switch on.
- Check that the tire pressure warning light turns on.
Ok: tire pressure warning light turns on.
- 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

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 ...
