TROUBLE DIAGNOSIS
Condition of Error DetectionINFOID:0000000001451948
“U1000” or “U1001” is indicated on SELF-DIAG RESULTS on CONSULT-III if CAN communication signal is
not transmitted or received between units for 2 seconds or more.
CAN COMMUNICATION SYSTEM ERROR
 CAN communication line open (CAN-H, CAN-L, or both)
 CAN communication line short (ground, betw een CAN communication lines, other harnesses)
 Error of CAN communication control circuit of the unit connected to CAN communication line
WHEN “U1000” OR “U1001” IS INDICATED EV EN THOUGH CAN COMMUNICATION SYSTEM IS
NORMAL
 Removal/installation of parts: Error may be detec ted when removing and installing CAN communication unit
and related parts while turning the ignition switch ON. (A DTC except for CAN communication may be
detected.)
 Fuse blown out (removed): CAN communication of the unit may cease.
 Voltage drop: Error may be detected if voltage drops due to discharged battery when turning the ignition
switch ON (Depending on the control unit which carries out CAN communication).
 Error may be detected if the power supply circuit of the control unit, which carries out CAN communication,
malfunctions (Depending on the control unit which carries out CAN communication).
 Error may be detected if reprogramming is not completed normally.
NOTE:
CAN communication system is normal if “U1000” or “U 1001” is indicated on SELF-DIAG RESULTS of CON-
SULT-III under the above conditions. Erase the memory of the self-diagnosis of each unit.
Symptom When Error Occurs in CAN Communication SystemINFOID:0000000001451949
In CAN communication system, multiple units mutually transmit and receive signals. Each unit cannot transmit
and receive signals if any error occurs on CAN communicati on line. Under this condition, multiple control units
related to the root cause malfunction or go into fail-safe mode.
ERROR EXAMPLE
NOTE:
 Each vehicle differs in symptom of each unit under fail-safe mode and CAN communication line wiring.
 Refer to LAN-37, "
Abbreviation List" for the unit abbreviation.
Example: TCM branch line open circuit

AUTO LIGHT SYSTEM
The headlamps will then illuminate. For a description of headlamp operation, Refer to LT- 5 , "System Descrip-
tion".
COMBINATION SWITCH READING FUNCTION
Refer to BCS-4, "System Description".
DELAY TIMER FUNCTION
Delay timer function carries out a function that BCM ac tivates the timer and controls lights out of headlamps by
door switch signal and lightning switch signal when turn ing the Ignition switch OFF while it is ON and head-
lamps are ON by the auto light function.
Timer types are a 5 minute timer and a 45 second timer
 When opening any door (door switch is ON), the 5 mi nute timer starts and then headlamps go out 5 minutes
later
 When all the doors are closed (from door switch ON to OFF), the 45 second timer starts and then headlamps go out 45 seconds later. If any door is opened (door switch ON) while the 45 second timer is in operation, the
5 minute timer starts again
 The timer stops when turning on the ignition switch or turning off the auto light switch under the above condi-
tions.
Delay timer control mode can be changed by the f unction setting of CONSULT-III or display.
CAN Communication System DescriptionINFOID:0000000001328308
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication s peed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CA N 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.
CAN Communication UnitINFOID:0000000001328309
Refer to LAN-43, "CAN System Specification Chart".
Major Component and FunctionsINFOID:0000000001328310
Components Functions
BCM  Turns on/off circuits of tail light and headlamp according to signals from light sensor, lighting switch (AUTO),
driver door switch, passenger door switch, rear door switch, and ignition switch (ON, OFF).
Optical sensor  Converts outside brightness (lux) to voltage, and sends it to BCM. (Detects brightness of 800 to 2,500 lux)

ENGINE OIL LEVEL
NOTE:
Before starting engine, put vehicle horizontally and check
the engine oil level. If engine is already started, stop
it and allow 10 minutes before checking.
1. Pull out oil level gauge and wipe it clean.
2. Insert oil level gauge and make sure the engine oil level is within the range shown in the figure.
3. If it is out of range, adjust it.
NOTE:
When checking the engine oil level, insert oil level gauge with its
tip aligned with oil level gauge guide on cylinder head. (In figure,
air cleaner case and air duct are removed.)
ENGINE OIL APPEARANCE
 Check engine oil for white turbidity or heavy contamination.
 If engine oil becomes turbid and white, it is highl y probable that it is contaminated with engine coolant.
Repair or replace damaged parts.
ENGINE OIL LEAKAGE
Check for engine oil leakage around the following areas:
 Oil pans (lower and upper)
 Oil pan drain plug
 Oil pressure switch
 Oil filter
 Oil filter bracket (AWD models)
 Oil cooler
 Water pump cover
 Chain tensioner cover
 Intake valve timing control cover and intake valve timing control solenoid valve
 Mating surface between cylinder head and rocker cover
 Mating surface between front timing chain case and rear timing chain case
 Mating surface between rear timing chain case and cylinder head
 Mating surface between rear timing chain case and cylinder block
