INSPECTION/VEHICLE SPEED SENSOR
Without ABS for the Middle East and Except for the
Middle East
CHECK VEHICLE SPEED SENSOR
OUTPUT.
1. Remove vehicle speed sensor from
transmission.
2. Check voltage between combination
meter connector
N4terminalsV22
(W) andV23(R) while quickly turning
speed sensor pinion.
Voltage: Approx. 0.5V
NG
cOK
Vehicle speed sensor is
OK.
CHECK VEHICLE SPEED SENSOR.
Check resistance between vehicle speed
sensor connector
E223terminalsV1(W)
and
V2(R).
Resistance: Approx. 250W
OK
cNG
Replace vehicle speed
sensor.
Check harness for open or short between
combination meter and vehicle speed
sensor.
INSPECTION/ENGINE REVOLUTION SIGNAL
CHECK ECM OUTPUT.
1. Start engine.
2. Check voltage between combination
meter terminal
V21(W) and ground at
idle and 2,000 rpm.
Higher rpm = Higher voltage
Lower rpm = Lower voltage
Voltage should change with rpm.

CONSULT-II DIAGNOSTIC TEST MODE FUNCTION
CONSULT-II DIAGNOSTIC TEST
MODEDescription
C/U INITIALIZATION When replacing any of the following components, C/U initialization is necessary.
[NATS ignition key/IMMU/ECM/Dongle unit]
SELF-DIAG RESULTS Detected items (screen terms) are as shown in the chart below.
NOTE:
When any initialization is performed, all ID previously registered will be erased. So all NATS ignition
keys must be registered again.
The engine cannot be started with an unregistered key. In this case, the system may show ªDIFFER-
ENCE OF KEYº or ªLOCK MODEº as a self-diagnostic result on the CONSULT-II screen.
When initialization is performed (for RHD models), security indicator will flash six times to demon-
strate recognition of dongle unit ID.
