DIAGNOSTIC TROUBLE CODE PROCEDURES
DTC B1001, B1002: Interior Temperature Sensor System.
DTC SET CONDITION
DTC B1001 is set if there is a short circuit in the
interior temperature sensor input circuit.
DTC B1002 is set if there is a defective connector
connection, or if there is an open circuit in the
harness.
.
TECHNICAL DESCRIPTION (COMMENT)
Current trouble
The A/C-ECU, the interior air temperature sensor,
or connector(s) or wiring between the two may be
defective.Past trouble
If DTC B1001 or B1002 is stored as a past trou-
ble, carry out diagnosis with particular emphasis
on wiring and connector(s) between the A/C-ECU
and the interior air temperature sensor. If the con-
nectors and wiring are normal, and obviously the
ECU is the cause of the trouble, replace the ECU.
If in doubt, do not replace the ECU.
.
TROUBLESHOOTING HINT
Malfunction of connector.
Malfunction of the harness.
Malfunction of the interior temperature sensor.
Malfunction of the A/C-ECU.

DTC B1011, B1012: Ambient Air Temperature Sensor System
If DTC B1011 or B1012 has been set, multi-dis-
play related DTC U1130 is also set. After B1011 or
B1012 has been diagnosed, don't forget to erase
DTC U1130.
.
DTC SET CONDITION
DTC B1011 is set if there is a short circuit in the
ambient air temperature sensor input circuit.
DTC B1012 is set if there is a defective connector
connection, or if there is an open circuit in the
harness.
