Description
When one of the steering wheel audio control switches is pushed, the resistance in the steering wheel audio control switch circuit changes, depending on which button is pushed.
Diagnosis Procedure
1.CHECK STEERING WHEEL AUDIO CONTROL SWITCH RESISTANCE
2.CHECK HARNESS BETWEEN COMBINATION SWITCH (SPIRAL CABLE) AND AV CONTROL UNIT
3.COMBINATION SWITCH (SPIRAL CABLE) CHECK
B2578, B2579 in-vehicle sensor
Description
In-vehicle Sensor
The in-vehicle sensor (1) is located on instrument lower cover
(LH).
It converts variations in compartment air temperature drawn from
the aspirator into a resistance value. It is then input into the A/C
auto amp.

Ignition signal
Description
The ignition signal from the ECM is sent to and amplified by the power
transistor. The power transistor turns
ON and OFF the ignition coil primary circuit. This ON/OFF operation induces the
proper high voltage in the coil
secondary circuit.
