Communication with Scan Tool is not possible.
(Communication with ABS only is not possible)
BJKG500T
DETECTING CONDITION
Trouble Symptoms
Possible Cause
When communication with Scan Tool is not possible, the
cause may be probably an open in the HECU power
circuit or an open in the diagnosis output circuit.
-
An open in the wire
-
Inoperative HECU
-
Inoperative power source circuit
INSPECTION PROCEDURES
CHECK FOR CONTINUITY IN THE DIAGNOSIS LINE
1.
Disconnect the connector from the ABS control mod-
ule.
2.
Check for continuity between terminals 11 of the ABS
control module connector and 1 of the data link con-
nector.
Is there continuity?
YES
▶
Check the power source of ABS control module.
NO
▶
Repair an open in the wire.
CHECK THE POWER SOURCE OF ABS CONTROL
MODULE
1.
Disconnect the connector from the ABS control mod-
ule.
2.
Turn the ignition switch ON, measure the voltage be-
tween terminal 18 of the ABS control module harness
side connector and body ground.
Specification: approximately B+
Is voltage within specification?
YES
▶
Check for poor ground.
NO
▶
Check the harness or connector between the fuse
(10A) in the engine compartment junction block and
the ABS control module.Repair if necessary.

BRAKE SYSTEM
When Ignition Key Is Turned ON (engine OFF), The ABS Warning Lamp Does Not Light Up.
EJBF505X
DETECTING CONDITION
Trouble 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.
-
Inoperative ABS warning lamp bulb
-
Blown No.2 fuse (10A) in the engine
compartment junction block
-
Inoperative ABS warning lamp module
-
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?
YES
▶
It is normal. Recheck the ABS control module.
NO
▶
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?
YES
▶
Repair bulb or instrument cluster assembly.
NO
▶
Check for blown fuse.

CHECK FOR BLOWN FUSE
Check continuity of fuse (10A) from the engine compart-
ment junction block.
Is there continuity?
YES
▶
Repair an open in the wire between ABS fuse and 1 of
cluster connector.
NO
▶
Replace the blown fuse.

Even After The Engine Is Started, The ABS Warning Lamp Remains ON.
EJBF505Y
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.
-
An open in the wire
-
Inoperative instrument cluster assembly
-
Inoperative ABS warning lamp module
-
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?
YES
▶
Repair circuit indicated by code output.
NO
▶
Check instrument cluster.
CHECK INSTRUMENT CLUSTER
Disconnect the cluster connector and turn the ignition
switch ON.
Does the ABS warning lamp remains ON?
YES
▶
Replace the instrument cluster.
NO
▶
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?
YES
▶
Replace the ABS control module and recheck.
NO
▶
Repair an open in the wire between cluster and ABS
control module.
