Problem symptom confirmation
Check if what the customer claimed in “Customer
Questionnaire” is actually found in the vehicle and if that
symptom is found, whether it is identified as a failure.
(This step should be shared with the customer if
possible.) Check warning lights related to brake system
referring to “EBD Warning Light (Brake Warning Light)
Check” and “ABS Warning Light Check”.
DTC check, record and clearance
Perform “DTC Check” proced ure, record it and then
clear it referring to “DTC Clearance”.
Recheck DTC referring to “DTC Check”.
When DTC which is recorded at DTC check procedure is
detected again after performi ng DTC clearance, go to
“Step 4: ABS Check: ” to proceed the diagnosis.
When DTC which is recorded at DTC check procedure is
not indicated anymore after performing DTC clearance,
ABS control module does not perform the system
diagnosis, or temporary abnormality may occur,
therefore go to “Step 2: Driving Test: ” to proceed the
diagnosis.
Step 2: Driving Test
Test drive the vehicle at 40 km/h for more than a minute
and check if any trouble symptom (such as abnormal
lighting of ABS warn ing light) exists.
If the malfunction DTC is co nfirmed again at ignition
switch ON, driving test as described is not necessary.
Proceed to Step 3.
Step 3: DTC Check
Recheck DTC referring to “DTC Check”.
Step 4: ABS Check
According to ABS Check for the DTC confirmation in
Step 3, locate the cause of the trouble, namely in a
sensor, switch, wire harness, connector, actuator
assembly or other part and repair or replace faulty parts.
Step 5: Brakes Diagnosis
Check the parts or system suspected as a possible
cause referring to “Brakes Symptom Diagnosis in
Section 4A” and based on symptoms appearing on the
vehicle (symptom obtained through Steps 1 and 2 and
repair or replace faulty parts, if any).
Step 6: Check for Intermittent Problem
Check parts where an intermittent trouble is easy to
occur (e.g., wire harness, con nector, etc.), referring to
“Intermittent and Poor Connection Inspection in Section
00” and related circuit of trouble code recorded in Step 1
to 3.
Step 7: Final Confirmation Test
Confirm that the problem symptom has gone and the
ABS is free from any abnormal conditions. If what has
been repaired is related to the malfunction DTC, clear
the DTC once referring to “DTC Clearance” and perform
test driving and confirm that no DTC is indicated.ABS Warning Light CheckS7RS0B4504002
1) Turn ignition switch ON.
2) Check that ABS warning light (1) comes ON for
about 2 seconds and then goes off.
If any faulty condition is found, advance to “ABS
Warning Light Does Not Come ON at Ignition Switch
ON” or “ABS Warning Light Comes ON Steady”.
EBD Warning Light (Brake Warning Light)
Check
S7RS0B4504003
NOTE
Perform this check on a level place.

1) Turn ignition switch ON with parking brake applied.
2) Check that EBD warning lig ht (brake warning light)
(1) is turned ON.
3) Release parking brake with ignition switch ON and check that EBD warning lig ht (brake warning light)
goes off.
If it doesn’t go off, go to “EBD Warning Light (Brake
Warning Light) Comes ON Steady”.

Step 3: DTC Check
Recheck DTC referring to “DTC Check”.
Step 4: ESP ® Check
According to ESP ® Check for the DTC confirmation in Step 3, locate the cause of the trouble, namely in a sensor,
switch, wire harness, connector, actuator assembly or other part and repair or replace faulty parts.
Step 5: Brakes Diagnosis
Check the parts or system suspected as a possible cause referring to “Brakes Symptom Diagnosis in Section 4A” and
based on symptoms appearing on the vehicle (symptom obtain ed through Steps 1 and 2 and repair or replace faulty
parts, if any).

Wiring Diagram
Circuit Description
Operation (ON/OFF) of ESP ® warning lamp is controlled by ESP ® control module through lamp driver module in
combination meter.
If ESP ® system is in good condition, ESP ® control module turns ESP ® warning lamp ON at the ignition switch ON,
keeps it ON for 2 seconds and then turns it OFF. If an abnormality in the system is detected, ESP ® warning lamp is
turned ON continuously by ESP ® control module. Also, it is turned ON continuously by lamp driver module when the
connector of ESP ® control module is disconnected.Inspection Item Referring section

Wiring Diagram4
Check ESP ® control module power supply circuit
1) Turn ignition switch to OFF position.
2) Check for proper connection to ESP ® control module
connector at terminals “E85-1” and “E85-32”.
3) If OK, then turn ignition switch to ON position and measure voltage between each terminal of “E85-1”,
“E85-32” and vehicle body ground.
Are they 10 – 14 V? Go to Step 5. “WHT/BLU” and/or
“WHT/RED” circuit
open.
5 Check ESP ® control module ground circuit
1) Turn ignition switch to OFF and measure resistance between each terminal of “E85-16”, “E85-47” and vehicle
body ground.
Is resistance less than 2
Ω? Go to Step 6.
Ground circuit for ESP®
control module open or
high resistance.
6 CAN communication circuit check
1) Check CAN communication circuit between combination
meter and ESP ® control module referring to “DTC
U1073: Control Module Communication Bus Off”.
Is CAN communication circuit in good condition? Substitute a known-
good combination meter
and recheck. If warning
lamp remains ON,
substitute a known-
good ESP
® hydraulic
unit / control module
assembly and recheck. Repair or replace.
