Models without automatic drive positioner
ECM
Harness connector E30
Harness connector M1
Models with automatic drive positioner
ECM
Harness connector E29
Harness connector B10
2.CHECK HARNESS FOR OPEN CIRCUIT
Disconnect the connector of ECM.
Check the resistance between the ECM harness connector terminals.

3.CHECK POWER SUPPLY AND GROUND CIRCUIT
Check the power supply and the ground circuit of the ECM. Refer to EC-157, "Diagnosis Procedure".

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.

CHECKING CVT FLUID
The fluid level should be checked with the fluid warmed
up to 50 to 80C (122 to 176F). The fluid level
check procedure is as follows:
Check for fluid leakage.
With the engine warmed up, drive the vehicle in
an urban area.
