During ABS operation, the brake pedal may vibrate or may not be able to be depressed. Such phenomena are
due to intermittent changes in hydraulic pressure inside the brake line to prevent the wheels from locking and is
not an abnormality.
DETECTING CONDITION
Trouble Symptoms Possible Cause
Brake operation varies depending on driving conditions and road
surface conditions, so diagnosis can be difficult.However if a normal
DTC is displayed, check the following probable cause. When the
problem is still occurring, replace the ABS control module. a.

DETECTING CONDITIONTrouble Symptoms Possible Cause
When current flows in the HECU the ABS warning lamp turns from
ON to OFF as the initial check.Therefore if the lamp does not light up,
the cause may be an open in the lamp power supply circuit, a blown
bulb, an open in the both circuits between the ABS warning lamp and
the HECU, and the inoperative HECU. a.
Inoperative ABS warning lamp bulb
b. Blown No.2 fuse (10A) in the engine
compartment junction block
c. Inoperative ABS warning lamp module
d. Inoperative HECU
INSPECTION PROCEDURES
PROBLEM VERIFICATION

▶ It is normal. Recheck the ABS control module.
▶ Check the power source for the ABS warning lamp.
CHECK THE POWER SOURCE FOR THE ABS WARNING LAMP
1. Disconnect the instrument cluster connector and turn the ignition switch ON.
2. Measure the voltage between terminal 8 of the cluster harness side connector and body ground.
Specification: approximately B+
Is voltage within specification?
▶ Repair bulb or instrument cluster assembly.
▶ Check for blown fuse.

CHECK FOR BLOWN FUSE
Check continuity of fuse (10A) from the engine compartment junction block.
Is there continuity?
▶ Repair an open in the wire between ABS fuse and 1 of cluster connector.
▶ Replace the blown fuse.
DETECTING CONDITION
Trouble Symptoms Possible Cause
If the HECU detects trouble, it lights the ABS warning lamp while at
the same time prohibiting ABS control. At this time, the HECU
records a DTC in memory.Even though the normal code is output, the
ABS warning lamp remains ON, then the cause may be probably an
open or short in the ABS warning lamp circuit. a.
An open in the wire
b. Inoperative instrument cluster assembly
c. Inoperative ABS warning lamp module
d. Inoperative HECU
INSPECTION PROCEDURES
CHECK DTC OUTPUT.
1. Connect the Scan Tool to the 16P data link connector located behind the driver's side kick panel.
2. Check the DTC output using Scan Tool.
Is DTC output ?
▶ Repair circuit indicated by code output.
▶ Check instrument cluster.
CHECK INSTRUMENT CLUSTER
Disconnect the cluster connector and turn the ignition switch ON.
Does the ABS warning lamp remains ON?
▶ Replace the instrument cluster.
▶ Check for open the wire.
CHECK FOR OPEN IN THE WIRE
Check for continuity in the wire between cluster and ABS control module.
Is there continuity?
▶ Replace the ABS control module and recheck.
▶ Repair an open in the wire between cluster and ABS control module.
BLEEDING OF BRAKE SYSTEM
1. Remove the reservoir cap and fill the brake reservoir with brake fluid.
If there is any brake fluid on any painted surface, wash it off immediately.

MODULE INTRODUCTION
FAM/IPM/RAM consists of a power board and an electronic board. The power board contains circuit protection devices
and switching devices. The electronic board uses Intelligent Power Switching (IPS) for HS/LS load control, logic
functions and CAN/K- Line communication. The power board and electronic board are connected with pin blocks for
the Front Area Module (FAM) and VCD (Variable Connection Displacement) for the In- Panel Module (IPM) and the
Rear Area Module (RAM).

Turn Signal And Side Repeater Lamps Function
1.Necessary conditions to switch ON(if they are standard) :
a. By activation of Crash Unlock
b. During the opening / closing of the Tail gate by the PTG Flasher input
c. With the Remote Keyless Entry to lock / unlock the vehicle
d. By alarm activation
e. By panic activation with the Remote Keyless Entry
f. By activation of the Hazard Lamp by the hazard switch and ignition is position OFF, ACC or RUN
g. By using the turn lever switch with the ignition switch in the ON position.
2. Necessary conditions to switch OFF(if they are standard) :
a. Ignition switch in OFF position for deactivation of crash unlock flashing
b. Deactivation of the alarm or at the end of the alarm flashing sequence
c. Deactivation of panic sequence with pushing any button of the Remote Keyless Entry or at the end of the panic
flashing sequence
d. Turn lever switch command in OFF postion or ignition switch in OFF, ACC or START position to stop turn lever
flashing.
e. The hazard switch in OFF position or ignition switch in position START to stop the Hazard flashing.
f. At the end of the Lock, Unlock and PTG flashing sequence.
3. During the start up of the vehicle (ignition key in position START) :
a. The Turn signal lamps activated by the turn lever switch are temporarily turned OFF. If the time duration in Start
position is more than 10seconds and engine running, the Turn signal lamps are managed again as if the ignition
key was in ON position,
b. The flashing sequence of the hazard lamps is immediately stopped if they have been activated by the hazard
button. If the time duration in Start position is more than 10seconds and engine running, the flashing sequence
of the hazard lamps are managed again as if the ignition key was in RUN position,
c. The flashing sequence of the hazard lamps is not stopped if they have been activated by a crash unlock.
