Vc output circuit
Description
The ecm constantly generates 5 v power from the battery voltages supplied to
the +b (batt) terminal to
operate the microprocessor. The ecm also provides this power to the sensors
through the vc output
circuit.
When the vc circuit is short-circuited, the microprocessor in the ...

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 (ecu-ig1)
