Kia Sedona (2008 year). Instruction — part 19

MONITOR SCAN TOOL DATA

1. Connect scan tool to Data Link Connector (DLC).

2. Ignition "ON".

3. Monitor the "Yaw rate sensor-lateral & Yaw rate sensor-yaw" parameter on the scan tool.

Specification: Lateral G sensor: ± 0 G, YAW rate Sensor: ± 0 deg/s

Case 1

Enable Conditions

> 4.7 V for a time t > =
100ms.



A line fault is detected if
V[YAW] < 0.225 V OR
V[YAW] > 4.774 V for a
time t > = 100 ms.



A line fault is detected if
V[YAW REFERENCE]
< 2.1 V OR V[YAW
REFERENCE] > 2.9 V
for a time t > = 200 ms.



Inoperative Yaw
Rate & Lateral G
sensor



Open or short of
Yaw Rate &
Lateral G sensor



Inoperative HECU

Case 2

DTC strategy



Self-test Monitoring

Monitoring Period



Once after power up and
no low voltage.

Enable Conditions



A line fault is detected if
0.2 V < V[LG] < 0.8 V
isn't continued for a time
t > = 60 ms during POS
(POS: power on self-test)

Fail Safe



Reduced controller
function.



Inhibit the ESC control
and ABS/EBD control is
available.



The ESC warning lamps
are activated.

4. Is parameter displayed within specifications?

YES



Fault is intermittent caused by poor connection in Yaw Rate & Lateral G sensor harness and/or
HECU's connector or was repaired and HECU memory was not cleared. Thoroughly check
connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or
damage. Repair or replace as necessary and then go to "VERIFICATION OF VEHICLE
REPAIR" procedure.

NO



Go to TERMINAL & CONNECTOR INSPECTION procedure.

TERMINAL & CONNECTOR INSPECTION

Refer to DTC C1102.

POWER SUPPLY CIRCUIT INSPECTION

1. Ignition "ON" & Engine "OFF".

2. Measure voltage between terminal "1" of the Yaw Rate & Lateral G sensor harness connector and chassis

ground.

Specification: Approx. B+

3. Is the measured voltage within specifications?

YES



Go to "GROUND CIRCUIT INSPECTION" procedure.

NO



Check for open or short to GND in the Yaw Rate & Lateral G sensor harness between terminal "1"
of the Yaw Rate & Lateral G sensor harness connector and battery +. Repair as necessary and then
go to "VERIFICATION OF VEHICLE REPAIR" procedure.

GROUND CIRCUIT INSPECTION

1. Ignition "OFF".

2. Disconnect Yaw Rate & Lateral G sensor connector.

3. Measure resistance between terminal "4" of the Yaw Rate & Lateral G sensor harness connector and

chassis ground.

Specification: Approx. below 1ohms

4. Is the measured resistance within specifications?

YES



Go to "SIGNAL CIRCUIT INSPECTION" procedure.

NO



Check for open or short in the Yaw Rate & Lateral G sensor harness between terminal "4" of the
Yaw Rate & Lateral G sensor harness connector and chassis ground. Repair as necessary and then
go to "VERIFICATION OF VEHICLE REPAIR" procedure.

SIGNAL CIRCUIT INSPECTION

1. Ignition "ON" & Engine "OFF".

2. Measure voltage between terminal "3,5,6" of the Yaw Rate & Lateral G sensor harness connector and

chassis ground.

Specification: Approx. 2.5 V ( Voltage between terminal "5, 6" of the Yaw Rate & Lateral G sensor
harness connector and chassis ground.)

3. Is the measured voltage within specifications?

YES



Go to "SELF TEST CIRCUIT INSPECTION" procedure.

NO



Check for open or short in the Yaw Rate & Lateral G sensor harness between terminal "3, 5, 6" of
the Yaw Rate & Lateral G sensor harness connector and terminal "16, 18, 20" of the chassis
ground. Repair as necessary and then go to "VERIFICATION OF VEHICLE REPAIR"
procedure.
