The Fuel Gauge Pointer Fluctuates, Indicator Wrong Value or VariesEKS00EHG
1. CHECK FUEL GAUGE FLUCTUATION
Test drive vehicle to see if gauge fluctuates only during driving and just before or soon after stopping.
Does the indication value vary only during driving and just before or soon after stopping?
YES >> The pointer fluctuation may be caused by fuel level change in the fuel tank. Condition is normal.
NO >> Ask the customer about the situation when the symptom occurs in detail, and perform the trouble
diagnosis.
The Fuel Gauge Does Not Move to FULL positionEKS00EHH
1. QUESTION 1
Does it take a long time for the pointer to move to FULL position?
YES or NO
YES >> GO TO 2.
NO >> GO TO 3.
2. QUESTION 2
Was the vehicle fueled with the ignition switch ON?
YES or NO
YES >> Be sure to fuel the vehicle with the ignition switch OFF. Otherwise, it will take a long time to move
to FULL position because of the characteristic of the fuel gauge.
NO >> GO TO 3.
3. QUESTION 3
Is the vehicle parked on an incline?
YES or NO
YES >> Check the fuel level indication with vehicle on a level surface.
NO >> GO TO 4.
4. QUESTION 4
During driving, does the fuel gauge pointer move gradually toward EMPTY position?
YES or NO
YES >> Check fuel level sensor unit. Refer to DI-30, "FUEL LEVEL SENSOR UNIT CHECK/GASOLINE
ENGINE MODELS" or DI-30, "FUEL LEVEL SENSOR UNIT CHECK/DIESEL ENGINE MOD-
ELS" .
NO >> The float arm may interfere or bind with any of the components in the fuel tank.

WARNING LAMPS

Electrical Components InspectionEKS002HK
OIL PRESSURE SWITCH CHECK
Check the continuity between the terminals of oil pressure switch
and ground.
DIODE CHECK

Check continuity using an ohmmeter.

Diode is functioning properly if test results are as shown in the
figure at left.

Check diodes at the combination meter harness connector
instead of on the combination meter assembly. Refer toDI-34,
"Wiring Diagram — WARN —/LHD Models" or DI-42, "Wiring
Diagram — WARN —/RHD Models" .
NOTE:
Specification may vary depending on the type of tester. Before
performing this inspection, be sure to refer to the instruction
manual for the tester to be used.

Inspection for Washer Nozzle EKS0032V
CHECK VALVE

Blow air in the injection direction, and check that air flows only
one way. Make sure that the reverse direction (inhale) is not
possible.
Removal and Installation for Wiper and Washer Switch EKS0032W
REMOVAL
1. Remove steering column cover.
2. Remove wiper washer switch connector.
3. Remove two screws then remove wiper washer switch from the
spiral cable.
INSTALLATION
Installation is in the reverse order of removal.

CAN COMMUNICATIONPFP:23710
System DescriptionEKS001U3
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 speed 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 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.
