ABS HYDRAULIC UNIT/CONTROL MODULE
ASSEMBLY
ABS control module is a component of ABS hydrauli unit / control
module assembly and has the following functions.
Self-Diagnosis Function
ABS control module diagnoses conditions of the system compo-
nent parts (whether or not there is any abnormality) all the time and
indicates the results (warning of abnormality occurrence and DTC)
through the ªABSº warning lamp as described below.
1) When ignition switch is turned ON, ªABSº warning lamp lights for
2 seconds to check its bulb and circuit.
2) When no abnormality has been detected (the system is in good
condition), ªABSº warning lamp turns OFF after 2 seconds.
3) When the vehicle starts to move after the ignition switch is turned
ON (more than one wheel speed sensor signals are inputted),
solenoid valves and motor of ABS hydraulic unit operate once
one after another for electrical check.
During this check, motor operation sound may be heard but that
means nothing abnormal.
4) When an abnormality in the system is detected, ªABSº warning
lamp lights and the area where that abnormality lies is stored in
the memory of EEPROM in ABS control module.
5) When Diag. switch terminal of diagnosis connector (monitor
connector) is grounded, the abnormal area is output as DTC. It
is indicated by flashing of ªABSº warning lamp. (Refer to the
table below. )

For procedure to clear all DTC's, refer to the item ªDiagnostic
Trouble Code Clearanceº in this section.
Also ABS control module turns ON EBD warning lamp (brake warn-
ing lamp) depending on the trouble that detected by the module and
EBD warning lamp does not indicate DTC as well as ªABSº warning
lamp.
Fail-Safe Function
When an abnormality occurs (an abnormal DTC is detected), ABS
control module turns OFF the fail-safe relay which supplies power
to ABS hydraulic unit. Thus, with ABS not operating, brakes func-
tion just like the brake system of the vehicle not equipped with ABS.

1-2. 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.) When ªABSº warning lamp is not operated correctly, proceed to ªDiagnostic Flow Table-A, B or
Cº.
1-3. DIAGNOSTIC TROUBLE CODE (DTC) CHECK, RECORD AND CLEARANCE
Perform ªDiagnostic Trouble Code Checkº as shown below, record it and then clear it referring to ªDiagnostic
Trouble Code Clearanceº in this section.
If the malfunction DTC which was once displayed and then cleared cannot be detected (indicated) again when
the ignition switch is turned ON, attempt to diagnose the trouble based on the DTC recorded in this step may
mislead the diagnosis or make diagnosing difficult. Proceed to Step 2 to check ABS control module for proper
self-diagnosis function.
If the malfunction DTC which was once displayed and then cleared can be detected (indicated) again when
ignition switch is turned ON, proceed to Step 3.
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 ªABSº warning lamp) exists.
If the malfunction DTC is confirmed again at ignition switch ON, driving test as described in above is not neces-
sary. Proceed to Step 3.
3. DIAGNOSTIC TROUBLE CODE CHECK
Recheck diagnostic trouble code referring to item ªDTC CHECKº as shown below.
4. DIAGNOSTIC TROUBLE CODE FLOW CHART
According to Diagnostic flow table for the diagnostic trouble code confirmed in Step 3, locate the cause of the
trouble, namely in a sensor, switch, wire harness, connector, actuator, ABS control module or other part and
repair or replace faulty parts.
5. ªDIAGNOSISº IN ªBRAKEº SECTION
Check the parts or system suspected as a possible cause referring to ªDiagnosisº in ªBRAKESº section and
based on symptoms appearing on the vehicle (symptoms obtained through Steps 1-1, 1-2 and 2 and repair or
replace faulty parts, if any.
6. CHECK FOR INTERMITTENT PROBLEM
Check parts where an intermittent trouble is easy to occur (e.g., wire harness, connector, etc.), referring to IN-
TERMITTENT TROUBLE in ªGENERAL INFORMATIONº section and related circuit of trouble code recorded
in Step 1-3.
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 and perform test driving and confirm that a nor-
mal code is indicated.

EBD WARNING LAMP (BRAKE WARNING
LAMP) CHECK
NOTE:
Perform this check on a level place.
1) Turn ignition switch ON with parking brake applied.
2) Check that brake warning lamp is turned ON.
3) Release parking brake with ignition switch ON and check that
EBD warning lamp (brake warning lamp) goes off.
If it doesn't go off, go to ªTABLE-Eº in this section.
ªABSº WARNING LAMP CHECK
1) Turn ON the ignition switch.
2) Check that ªABSº warning lamp lights for about 2 seconds and
then goes OFF.
If anything faulty is found, advance to Diagnostic table ± A, B or
C.
DIAGNOSTIC TROUBLE CODE (DTC) CHECK
(USING ªABSº WARNING LAMP)
1) Using service wire, connect diag. switch terminal of diagnosis
connector to ground.
2) Turn ignition switch ON.
3) Read flashing of ªABSº warning lamp which represents DTC as
shown in example below and write it down. When more than 2
DTC's are stored in memory, deflection and flashing for each
DTC is repeated three times starting with the smallest DTC num-
ber in increasing order.
For details of DTC, refer to ªDTC Tableº.

NOTE:
ªABSº warning lamp indicates only following DTC's, DTC
12 which means that no malfunction DTC is stored and his-
tory DTC which indicates history trouble area. When there
is a current trouble, ªABSº warning lamp remains ON and
therefore DTC is not indicated.
4) After completing the check, turn ignition switch off and discon-
nect service wire from DIAG. connector.
