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.

TABLE ± A ªABSº WARNING LAMP CIRCUIT CHECK ± LAMP DOES NOT
COME ªONº AT IGNITION SWITCH ON
CIRCUIT DESCRIPTION
Operation (ON / OFF) of the ªABSº warning lamp is controlled by the ABS control module and ABS lamp driver mod-
ule.
If the Antilock brake system is in good condition, the ABS control module turns the ªABSº warning lamp ON at the
ignition switch ON, keeps it ON for 2 seconds only and then turns it OFF. If an abnormality in the system is detected,
the lamp is turned ON by ABS control module. Also, it is turned ON by ABS lamp driver module when the connector
of the ABS control module was disconnected.

11) Turn ignition switch ON.
Do other warning lamp come ON?Go to step 2.Go to step 4.
21) Disconnect ABS hydraulic unit / control module
connector.
Does ABS warning lamp light with ignition switch ON?Replace ABS
hydraulic unit / control
module assembly.Go to step 3.
31) Remove combination meter.
Is bulb of ABS warning lamp in good condition?ªBl / Oº circuit shorted
to ground. If OK,
replace ABS
warning circuit (lamp

CIRCUIT DESCRIPTION
When the diag. switch terminal is connected to the ground with the ignition switch turned ON, the ABS control mod-
ule outputs a diagnostic trouble code by flashing ªABSº warning lamp.
INSPECTION

1Is it shorted diag. switch terminal and ground terminal by
service wire properly?Go to step 2.Connect service
wire securely.
21) Disconnect service wire.
2) Disconnect ABS hydraulic unit / control module
connector. (See Fig. 1)
3) Measure resistance between diag. switch terminal
and connector terminal ªA8º.
Is it infinite (
)?ªPº circuit open.Go to step 3.
31) Measure resistance between ground terminal of
monitor connector and body ground.
Is continuity indicated?Go to step 4.ªBº circuit open or

41) Check for proper connection to ABS hydraulic
unit / control module at terminal ªA8º and ªA10º.
2) If OK, then check ªABSº warning lamp circuit
referring to ªTABLE A, B and Cº.
Is it in good condition?Substitute a
known-good ABS
