Step

Examine the acceleration sensor.

Are there any signs of physical damage?
1. Turn the ignition switch to ON.

2. Use a digital voltmeter (DVM) to measure the

voltage between terminal 28 and 23 of EBCM.

Is the voltage within the specified value?
Replace the acceleration sensor.

Is the repair complete?
Repair the open in the affected circuit or replace the
acceleration sensor, if necessary.

Is the repair complete?

1. Place the acceleration sensor horizontally and let

the acceleration sensor.

2. Turn the ignition switch to ON.

3. Use a digital voltmeter (DVM) to measure the

voltage between terminal 28 and 10 of EBCM.

Is the voltage within the specified value?

Repair the open in the affected circuit or replace the
acceleration sensor, if necessary.

Is the repair complete?
Replace the ABS unit.

DIAGNOSTIC TROUBLE CODE (DTC) - ACCELERATION SENSOR

CONTINUITY FAULT

YAD4E220

Circuit Description

The acceleration sensor provides a voltage signal that
changes in relation to the acceleration of vehicle. The
signal voltage will vary from about 1.95 to 3.45 volt.
The electronic brake control module (EBCM) monitor a
signal voltage of deceleration in the vehicle.

acceleration sensor, a short to ground or to voltage in
the wiring, or a contact problem in a connector.

Cause

•

The vertical acceleration sensor is defective or
disconnected.

•

There is a problem in the wiring.

•

There is a problem with a connector

•

Wrong installed vertical acceleration sensor

Action Taken When the DTC Sets

ABS action 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 the voltage reference from

the EBCM.

5. This step checks for the voltage signal from the

acceleration sensor.

Diagnostic Aids

Be sure that the acceleration sensor wiring is properly
routed and retained.

It is very important to perform a thorough inspection
of the wiring and the connectors carefully and
completely may result in misdiagnosis, causing part
replacement with the reappearance of the malfunction.

You can use the scan tool to monitor acceleration sensor
during a road test. Watch the acceleration sensor being
display on the scan tool to see if any of the reading is
unusual.

DIAGNOSTIC TROUBLE COED (DTC) 060/065 - LEFT FRONT INLET AND

OUTLET VALVE SOLENOID FAULT

YAD4E230

Circuit Description

The solenoid valve coil circuits are supplied with power
from the battery when the valve relay is energized.
Switched ground is provided by the electronic brake
control module (EBCM) to each coil.

Diagnosis

This procedure checks whether the left front inlet and
outlet valves are functioning.

Cause

•

A valve has failed.

•

A solenoid coil is open or shorted.

Action Taken When the DTC Sets

ABS is disabled, and the ABS warning lamp is turned
ON for the remainder of the ignition cycle. If the failure
is intermittent, the EBCM will enable the system at the
next ignition cycle and set a history DTC.

Test Description

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

1. This step begins the test of the inlet valve

3. This step tests the outlet valve.
