DESCRIPTION
The primary purpose of the SRSCM (Supplemental Restraints System Control Module) is to discriminate between an
event that warrants restraint system deployment and an event that does not. The SRSCM must decide whether to
deploy the restraint system or not. After determining that pretensioners and/or airbag deployment is required, the
SRSCM must supply sufficient power to the pretensioners and airbag igniters to initiate deployment. The SRSCM
determines that an impact may require deployment of the pretensioners and airbags from data obtained from impact
sensors and other components in conjunction with a safing function. The SRSCM will not be ready to detect a crash or
to activate the restraint system devices until the signals in the SRSCM circuitry stabilize. It is possible that the SRSCM
could activate the safety restraint devices in approximately 2 seconds but is guaranteed to fully function after prove-
out is completed. The SRSCM must perform a diagnostic routine and light a system readiness indicator at key - on. The
system must perform a continuous diagnostic routine and provide fault annunciation through a warning lamp indicator
in the event of fault detection. A serial diagnostic communication interface will be used to facilitate servicing of the
restraint control system.

b. HECU
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.
Inoperative power source circuit
b. Inoperative wheel speed sensor circuit
c. Inoperative hydraulic circuit for leakage
d. Inoperative HECU
INSPECTION PROCEDURES
DTC INSPECTION
1. Connect the Scan Tool with the data link connector and turn the ignition switch ON.
2. Verify that the system is operating to specifications.
Is the system operating to specifications ?
▶ Check the power source circuit.
▶ Erase the DTC and recheck using Scan Tool.
CHECK THE POWER SOURCE CIRCUIT.
1. Disconnect the connector from the ABS control module.
2. Turn the ignition switch ON, measure the voltage between terminal 18 of the ABS control module harness side
connector and body ground.
Specification: approximately B+
Is the voltage within specification?
▶ Check the ground circuit.
▶ Check the harness or connector between the fuse (10A) in the engine compartment junction block and the ABS
control module. Repair if necessary.

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
Disconnect the connector from the ABS control module and turn the ignition switch ON.
Does the ABS warning lamp light up?
▶ 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.

DESCRIPTION
The EBD system (Electronic Brake force Distribution) as a sub- system of the ABS system is to control the effective
adhesion utilization by the rear wheels.
It further utilizes the efficiency of highly developed ABS equipment by controlling the slip of the rear wheels in the
partial braking range.
The brake force is moved even closer to the optimum and controlled electronically, thus dispensing with the need for
the proportioning valve.
The proportioning valve, because of a mechanical device, has limitations to achieve an ideal brake force distribution
tothe rear wheels as well as to carry out the flexible brake force distribution proportioning to the vehicle load or weight
increasing. And in the event of malfunctioning, driver cannot notice whether it fails or not.
EBD controlled by the ABS Control Module, calculates the slip ratio of each wheel at all times and controls the brake
pressure of the rear wheels not to exceed that of the front wheels.
If the EBD fails, the EBD warning lamp (Parking brake lamp) lights up.
ADVANTAGES
a.Function improvement of the base - brake system.
b. Compensation for the different friction coefficients.
c. Elimination of the proportioning valve.
d. Failure recognition by the warning lamp.
