2007 NISSAN LATIO engine

DI-20
COMBINATION METERS
Revision: June 20062007 Versa
Engine Speed Signal Inspection EKS00I0H
Symptom: Improper tachometer indication.
1. CHECK COMBINATION METER INPUT SIGNAL
1. Start engine and select “METER” on CONSULT-II.
2. Using “TACHO METER” on “DATA MONITOR”, compare the
value of “DATA MONITOR” with tachometer pointer of combina-
tion meter.
OK or NG
OK >> Perform ECM self-diagnosis. Refer to EC-116, "SELF-
DIAG RESULTS MODE" .
NG >> Replace combination meter. Refer to IP-19, "
COMBINA-
TION METER" .
Fuel Level Sensor Signal InspectionEKS00I0J
Symptom:

Improper fuel gauge indication.

Low-fuel warning lamp indication is irregular.
NOTE:
The following symptoms do not indicate a malfunction.

Depending on vehicle position or driving circumstance, the fuel level in the tank shifts and the indication
may fluctuate.

If the vehicle is fueled with the ignition switch ON, the indication will update slowly.

If the vehicle is tilted when the ignition switch is turned ON, fuel in the tank may flow to one direction
resulting in a change of reading.
1. CHECK COMBINATION METER INPUT SIGNAL
1. Select “METER” on CONSULT-II.
2. Using “FUEL METER” on “DATA MONITOR”, compare the value
of “DATA MONITOR” with fuel gauge pointer of combination
meter.
OK or NG
OK >> GO TO 2.
NG >> Replace combination meter. Refer to IP-19, "
COMBINATION METER" .
2. CHECK HARNESS CONNECTOR
1. Turn ignition switch OFF.
2. Check combination meter and fuel level sensor unit terminals (meter-side and harness-side) for poor con-
nection.
OK or NG
OK >> GO TO 3.
NG >> Repair or replace terminals or connectors.
