2007 KIA CARNIVAL Workshop Manual

1.ABS WARNING LAMP MODULE
The active ABS warning lamp module indicates the selftest and failure status of the ABS.The ABS warning lamp
shall be on:
a. During the initialization phase after IGN ON. (continuously 3 seconds).
b. In the event of inhibition of ABS functions by failure.
c. During diagnostic mode.
d. When the ECU Connector is seperated from ECU.
2. PARKING/EBD WARNING LAMP MODULE
The active EBD warning lamp module indicates the selftest and failure status of the EBD.However, in case the
Parking Brake Switch is turned on, the EBD warning lamp is always turned on regardless of EBD functions.The
EBD warning lamp shall be on:
a. During the initialization phase after IGN ON. (continuously 3 seconds).
b. When the Parking Brake Switch is ON or brake fluid level is low.
c. When the EBD function is out of order.
d. During diagnostic mode.
e. When the ECU Connector is seperated from ECU.

STANDARD FLOW OF DIAGNOSTIC TROUBLESHOOTING
NOTES WITH REGARD TO DIAGNOSIS
The phenomena listed in the following table are not abnormal.
Phenomenon Explanation
System check sound When starting the engine, a thudding sound can sometimes be heard coming
from inside the engine compartment. This is because the system operation check
is being performed.
ABS operation sound a.Sound of the motor inside the ABS hydraulic unit operation (whine).
b. Sound is generated along with vibration of the brake pedal (scraping).
c. When ABS operates, sound is generated from the vehicle chassis due to
repeated brake application and release
(Thump : suspension; squeak: tires)
ABS operation (Long braking
distance) For road surfaces such as snow- covered and gravel roads, the braking distance
for vehicles with ABS can sometimes be longer than that for other vehicles.
Accordingly, advise the customer to drive safely on such roads by lowering the
vehicle speed.
Diagnosis detection conditions can vary depending on the diagnosis code. When checking the trouble symptom after
the diagnosis code has been erased, ensure that the requirements listed in "Comment" are met.
SCAN TOOL (PRO) CHECK
1. Turn the ignition switch OFF.
2. Connector the Scan tool to the 16P data link connector located the driver's side kick panel.

3.Turn the ignition switch ON.
4. Check for DTC using the Scan tool
5. After completion trouble of the repair or correction of the problem, erase the stored fault codes using the scan tool.
6. Disconnect the Scan tool from the 16P data link connector.
ABS CHECK SHEET

PROBLEM SYMPTOMS TABLE
SymptomSuspect Area
ABS does not operate. Only when 1. - 4. are all normal and the problem is still
occurring, replace the HECU.
a. Check the DTC reconfirming that the normal code is
output.
b. Power source circuit.
c. Speed sensor circuit.
d. Check the hydraulic circuit for leakage.
ABS does not operate intermittently. Only when 1. - 4. are all normal and the problem is still
occurring, replace the ABS actuator assembly.
a. Check the DTC reconfirming that the system is
operating to specifications.
b. Wheel speed sensor circuit.
