INSPECTION PROCEDURE
1
Check voltage between terminals TAM and SG–TAM of integration control and
panel.
PREPARATION:
Remove the integration control and panel with connectors still
connected.
CHECK:
(a)
Turn the ignition switch to ON.
(b)
Measure the voltage between terminals TAM and SG–
TAM of the integration control and panel connector at
each temperature.
OK:
Voltage :
at 25
°
C (77
°
F) : 1.35 to 1.75 V
at 40
°
C (104
°
F) : 0.85 to 1.25 V
HINT:
As the temperature increases, the voltage decreases.
NG
OK
Proceed to next circuit inspection shown in problem symptoms table (See page
ever, if DTC 12 is displayed, replace integration control and panel.

NOTICE:
Even slightly touching the sensor may change the re-
sistance value. Be sure to hold the connector of the
sensor.
When measuring, the sensor temperature must be
the same as the ambient temperature.
HINT:
As the temperature increases, the resistance decreases (see
the graph on the left).
NG
Replace ambient temperature sensor.
OK
3
Check harness and connector between ambient temperature sensor and integra-
tion control and panel (See page
).
NG
Repair or replace harness or connector.
OK
Replace integration control and panel.
