THE AMBIENT TEMPERATURE DISPLAY IS INCORRECT
DescriptionINFOID:0000000003792615
 The displayed ambient air temperature is higher than the actual temperature.
 The displayed ambient air temperature is lower than the actual temperature.
Diagnosis ProcedureINFOID:0000000003792616
NOTE:
Check that the symptom is not applicable to the normal operating condition before starting diagnosis. Refer to
MWI-124, "
INFORMATION DISPLAY : Description".
1.CHECK AMBIENT SENSOR SIGNAL CIRCUIT
Check the ambient sensor signal circuit.
 Refer to HAC-45, "
Diagnosis Procedure" (without 7 inch display).
 Refer to HAC-167, "
Diagnosis Procedure" (with 7 inch display).
Is the inspection result normal?
YES >> GO TO 2.
NO >> Repair harness or connector.
2.CHECK AMBIENT SENSOR UNIT
Perform a unit check for the ambient sensor.
 Refer to HAC-46, "
Component Inspection" (without 7 inch display).
 Refer to HAC-168, "
Component Inspection" (with 7 inch display).
Is the inspection result normal?
YES >> Replace combination meter.
NO >> Replace ambient sensor. Refer to VTL-24, "
Removal and Installation" (without 7 inch display) or
VTL-81, "
Removal and Installation" (with 7 inch display).

NORMAL OPERATING CONDITION
INFORMATION DISPLAY
INFORMATION DISPLAY : DescriptionINFOID:0000000003792618
AMBIENT AIR TEMPERATURE
The displayed ambient air temperature on the information display may differ from the actual temperature
because it is a corrected value calculated from the ambient sensor signal by the combination meter. Refer to
MWI-27, "
INFORMATION DISPLAY : System Description" for details on the correction process.
POSSIBLE DRIVING DISTANCE
The calculated possible driving distance may differ from the actual distance to empty if the refueling amount is
approximately 15 (3-3/10 Imp gal) or less. This is because the refuel control (moves the fuel gauge needle
quicker than normal judging that the driver is refueling the vehicle) is not performing.

U1000 CAN COMM CIRCUIT
DescriptionINFOID:0000000003773269
CAN (Controller Area Network) is a serial communication line for real time applications. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Modern
vehicle is equipped with many electronic control unit, and each control unit shares information and links with
other control units during operation (not independent). In CAN communication, control units are connected
with 2 communication lines (CAN-H line, CAN-L line) allowing a high rate of information transmission with less
wiring. Each control unit transmits/receives data but selectively reads required data only.

h (2.5 MPH) or less.
 Turn the ignition relay OFF with the following operation when the vehicle speed is more than 4 km/h (2.5
MPH) or when an abnormal condition occurs in CAN communication from the combination meter (Emer-
gency OFF)
- Press and hold the push-button ignition switch for 2 seconds or more.
