1. Use a scan tool to clear all DTCs.
2. Road test the vehicle.
Does DTC 12 set again?
1. Check all system wiring harness connectors and

terminals, especially the electronic brake control
module(EBCM), for any problem that could cause
an intermittent condition.

2. Repair any intermittent problem found.
Is the repair complete?
Check fuse EF 22.
Is fuse EF22 blown?
1. Check for a short circuit and repair it, if necessary.
2. Replace fuse EF 21.
Is the repair complete?
1. Disconnect the valve relay.
2. Check the resistance between the valve relay

connector terminal 86 and terminal 2 of EBCM.

Is the resistance equal to the specified value?
Repair the open circuit between the valve relay
connector terminal 86 and terminal 2 of EBCM.
Is the repair complete?
Check the resistance between the valve relay connec-
tor terminal 85 and terminal 37 of EBCM.
Is the resistance equal to the specified value?
Repair the open circuit between the valve relay
connector terminal 85 and terminal 37 of EBCM.
Is the repair complete?
Check the voltage between the valve relay connector
terminal 30 and ground.
Is the voltage equal to the specified value?
Repair the open circuit between the valve relay
connector terminal 30 and fuse EF21.
Is the repair complete?
Check the resistance between the valve relay connec
tor terminal 87 and terminal 10 of hydraulic modulator.
Is the resistance equal to the specified value?
Replace the valve relay.
Is the repair complete?
1. Disconnect the EBCM.
2. Check the resistance between terminal 28 and 29

of EBCM and ground G303.

Is the resistance equal to the specified value?
Repair the open circuit between the valve relay
connector terminal 87 and terminal 14 of hydraulic
modulator.
Is the repair complete?
Replace the ABS unit.

DIAGNOSTIC TROUBLE CODE (DTC) 24

PUMP MOTOR OR PUMP MOTOR RELAY FAULT

KAA4F220

Circuit Description

When the electronic brake control module (EBCM)
grounds the pump motor relay, it closes and provides
battery voltage to the pump motor. The EBCM senses
the voltage applied to the pump motor to verify motor
operation.

Diagnosis

This DTC sets when the EBCM detects B+ without mo
tor relay activation or if the EBCM does not detect B+
after motor relay activation.

Cause(s)

•

There is a faulty terminal in the pump motor connector.

•

There is a faulty terminal in EBCM connector.

•

There is a problem in the ABS wiring harness.

•

There is high resistance in the chassis ground.

•

The EBCM is defective.

•

There is a problem in the wiring from the pump motor
connector to the motor.

Fail Action

ABS is disabled, and the ABS warning lamp is ON.

Test Description

The number(s) below refer to step(s) on the diagnostic
table.

2. This step checks for poor connection.

5. This step checks for the motor relay.

13. This step checks for the hydraulic modulator.

Diagnostic Aids

It is very important to perform a thorough inspection of
the wiring and the connectors. Failure to do so may re-
sult in misdiagnosis, causing part replacement with the
reappearance of the malfunction.
