4F-88 ABS AND TCS
DIAGNOSTIC TROUBLE CODE (DTC) 02
ABS CONTROL MODULE INTERNAL FAULT
KAA4F240
Circuit Description
The ABS control module performs various diagnostic
checks on itself. If it finds a problem, it sets DTC 02.
Diagnosis
This procedure checks whether there is a poor ground
connection for the electronic brake control module
(EBCM).
Cause(s)
A connector terminal is corroded.
The EBCM is malfunctioning.
Fail Action
ABS is disabled, and the ABS warning lamp is turned
ON. If the failure is intermittent, the control module will
enable the system at the next ignition cycle and will
store a history DTC 02.Test Description
The number(s) below refer to step(s) on the diagnostic
table.
3. This step begins the testing for a poor voltage or
ground connection.
Diagnostic Aids
It is very important to perform a thorough inspection of
the wiring and the connectors. Failure to inspect the
wiring and the connectors carefully and completely may
result in misdiagnosis, causing part replacement with
the reappearance of the malfunction.

nals, especially those at the EBCM, for any
condition that could cause an intermittent.
2. Repair any problems found.
Is the repair complete?
1. Turn the ignition to OFF.
2. Disconnect the EBCM connector.
3. Turn the ignition to ON.
4. Measure the voltage between ground and termi-
nals 50 and 1 of the EBCM harness connector.
Is the voltage equal to the specified value?
1. Check the voltage supply and the ground connec-
tions to the EBCM.
2. Repair any open or high resistance found.
Is the repair complete?
Check the EBCM connector for any damaged termi-
nals.
Are there any problems?
Repair any connector problem found.
Is the repair complete?
Clear all DTCs and road test the vehicle.
