BRAKE SYSTEM
DTC C1261 STEERING ANGLE SENSOR IS NOT CALIBRATED
COMPONENT LOCATION
ED186D22
Refer to DTC C1260.
GENERAL DESCRIPTION
E2B7726C
Refer to DTC C1260.
DTC DESCRIPTION
EF8998E6
The SAS used for ESP control needs zero point adjustment because the SAS measures an absolute angle. Zero point
adjustment is done by using the scantool device. If abnormal zero point adjustment is detected, a failure is recognized.
DTC DETECTING CONDITION

Item
Detecting Condition
Possible cause
DTC Strategy
• Signal Monitoring
Monitoring
Period
• During SAS zero point adjustment.
Enable
Conditions
• The position of steering wheel is out of specified
range (straight positon, a max. error ±5 ) during
SAS zero point adjustment.
Fail Safe
• Reduced controller function caused by inoperative SAS
signal. ABS/EBD control is available.
• The ESP warning lamp is activated.
• A fail of SAS zero point
adjustment
• Inoperative HECU

MONITOR SCANTOOL DATA
E94D13A2
1.
Connect scantool to Data Link Connector(DLC).
2.
Ignition "ON"
&
Engine "ON".
3.
Monitor the "SAS CALIBRATED" parameters on the Scantool.
Specification : YES
Fig 1) SAS Calibrate normal data - YES : SAS calibrated, NO : SAS not calibrated.

4.
Is parameter displayed within specifications?
YES
▶
Fault is caused by having been repaired and HECU memory was not cleared. Clear the DTC and then go to
"Verification Of Vehicle Repair" procedure.
NO
▶
Go to "Component Inspection" procedure.

1.
Line up wheels like (figure 1).
1)
Perform the wheel alignment.
2)
Line up the steering wheel in a straight.
3)
Go ahead and Go back the vehicle 2~3 times without holding steering wheel.
2.
Connect scantool to Data Link Connector(DLC).
3.
Go in Anti-Lock brake system. (figure 2).
4.
Perform steering angle sensor calibration. (figure 3).
5.
Disconnect scantool.
6.
Check the condition of SAS zero point adjustment by operating the vehicle (turn right and left at least 1 time)

7.
Is zero point adjustment completed?
YES
▶
Go to "Verification Of Vehicle Repair" procedure.
NO
▶
Substitute with a known-good HECU and check for proper operation. If problem is corrected, replace HECU and
then go to "Verification Of Vehicle Repair" procedure.

DTC C1282 YAW RATE AND LATERAL G SENSOR - ELECTRICAL
COMPONENT LOCATION
ECB9896F
EJBF503C
GENERAL DESCRIPTION
E5DF85C9
The yaw-rate and G sensor assembly is installed on the lower floor. The yaw-rate sensor detects acceleration of the
vehicle around its vertical axis, while the G sensor detects lateral acceleration of the vehicle. When the vehicle is not
moving, the G sensor output is approximately 2.5 V.
DTC DESCRIPTION
E1B3F4C4
The HECU monitors a signal voltage of either yaw-rate sensor or lateral G sensor to detect open or short to battery or
short to ground. A failure is detected if the lateral acceleration sensor or yaw rate sensor signal voltage stays in the fault
range longer than 100 ms or the lateral acceleration sensor or yaw rate sensor reference voltage stays in the fault range
longer than 200 ms, or the self test form is against specification during self test.
