DIAGNOSIS
KAA4F110
DIAGNOSTIC CIRCUIT CHECK
The Diagnostic Circuit Check is an organized approach
to identifying a problem created by an antilock brake
system (ABS) malfunction. If must be the starting point
for any ABS complaint diagnosis because it directs
the service technician to the next logical step in
diagnosing the complaint.
Diagnostic Process
Perform the following steps in order when servicing
the ABS/TCS system. Failure to do so may result in
the loss of important diagnostic data and may lead to
difficulties and time-consuming diagnosis procedures.
1. Perform the tests of the table below.2. Perform a road test if directed by the table.
Test drive the vehicle while using the snapshot
feature of the scan tool.
Perform normal acceleration, stopping, and
turning maneuvers.
If this does not reproduce the malfunction,
perform an ABS stop or TCS maneuver on a low
friction surface such as gravel.
3. Clear the diagnostic trouble codes (DTCs) after
all system malfunctions have been corrected.

4F-16 ABS AND TCS
1. Install the scan tool.
2. Turn ignition switch to ON.
3. Select the Data List mode.
Is the scan tool receiving data from the electronic
brake control module (EBCM)?
Check the display.
Are there any current DTCs displayed?
1. Turn the ignition to LOCK for 10 seconds.
2. Turn the ignition to ON and observe the ABS
indicator.
Does the indicator light for 2 seconds and then go off?
Check the ABS indicator.
Did the ABS indicator turn on and stay on?
Check whether the vehicle is equipped with traction
control.
Is the vehicle equipped with traction control?
1. Turn the ignition to LOCK for 10 seconds.
2. Turn the ignition to ON and observe the TCS
indicator.
Does the indicator light for 2 seconds and then go off?
1. Turn the ignition to LOCK.
2. Disconnect the EBCM harness connector.
3. Turn the ignition to ON.
4. Use a digital voltmeter (DVM) to measure the
voltage from ground to terminal 1 and 50 of the
EBCM harness connector.
Is the voltage equal to the specified value?
1. Turn the ignition to LOCK.
2. Use a DVM to measure the resistance from the EBCM
harness connector, terminals 28 and 29 to ground.
Is the resistance equal to the specified value?
Repair the open in the circuit that failed.
Is the repair complete?
Use a DVM to measure the resistance between
terminal 46 of the EBCM harness connector and
terminal 8 of the data link connector (DLC).
Is the resistance below the specified value?
Replace the ABS unit.
Is the repair complete?
Repair the open or high resistance in circuit BrG
between terminal 11 of the EBCM harness connector
and terminal 13 of the DLC.
Is the repair complete?
Perform the road test described above.
Are any DTCs set? Step
