Diagnostic Aids

DTC 11 may be set by running the scan tool auto test
if the throttle angle readings are not updating while in
the date list mode. If this is the case, clear the DTCs,
disconnect the scan tool, and road test the vehicle to
at least 25 km/h (15 mph) to see if the DTC resets.

Check the toothed wheels for any large grooves,
gouges, marks, etc. that might influence the tooth’s
signal at the wheel speed sensor. Also, check for a
buildup of foreign material in the gaps between the

teeth in the toothed wheel, as this material may cause
this malfunction.

A badly worn hub/bearing assembly may cause this
malfunction. The wheel speed sensor-to-toothed wheel
air gap may change excessively due to bearing play.

If an improper rear hub assembly or front outer constant
velocity joint is installed, one with a toothed wheel
containing the incorrect number of teeth, this DTC can
set. Be sure that all the toothed wheels have 52 teeth.

Step

Visually inspect the wiring for the front wheel speed
sensors.

Is there any damage?
Repair or replace components, as required.

Is the repair complete?
Check that the correct outer constant velocity (CV)
joints are installed on the vehicle, They should have
speed rings with 52 teeth.

Is one of these incorrect?

Replace the incorrect outer CV joint with the proper
unit.
Is the repair complete?

1. Disconnect the wheel speed sensor harnesses

from the wheel speed sensor connectors.

2. Measure the wheel speed sensor resistance at the

wheel speed sensor connector terminals.

Does the resistance fall within the specified values for
both wheel speed sensors?

Replace the faulty wheel speed sensor.
Is the repair complete?

1. Disconnect the ABS control module connector.

2. Check each wheel speed sensor harness for a

short circuit between its wires with a digital
ohmmeter attached to the two terminals at the
harness side of the wheel speed sensor connector.

3. Also check each wheel speed sensor harness wire

for a short to ground from the connector terminals.

Is there any short circuit in either wheel speed sensor
harness?
Repair the short circuit tin the wiring or from a wiring
harness to ground.

Is the repair complete?

Check the continuity of the wiring in both front wheel
speed sensor circuits between the EBCM connector
and the wheel speed sensor connector an each side of
the vehicle.

•

The left side uses terminals 7 and 6 at the EBCM
connector.

•

The right side uses terminals 4 and 5 at the EBCM
connector.

Is continuity good for both harnesses?

Step

Repair the discontinuity found in the front wheel speed
sensor harness or connector C110.

Is the repair complete?
1. Visually inspect the wiring for the rear wheel speed

sensors.

2. Check that the wheel speed sensors are properly

mounted and that the retaining belts are properly
tightened.

Is there any damage?
Remove each wheel speed sensor from the rear axle
and inspect the toothed ring through the wheel speed
sensor mounting holes.

•

Make sure that the toothed ring has 52 teeth.

•

Check for any damaged or missing teeth.

•

Check that the ring is properly positioned under the

wheel speed sensor.

Is there any damage or other fault with either speed
ring?
Replace the rear wheel hub with the proper unit.

Is the repair complete?
1. Disconnect the rear wheel speed sensor harnesses

from the wheel speed sensor connectors.

2. Measure the wheel speed sensor resistance at the

wheel speed sensor connector terminals.

Does the resistance fall within the specified values for
both wheel speed sensors?
Replace the faulty wheel speed sensor.

Is the repair complete?

1. The ABS control module connector should still be

disconnected. Disconnect it now if it is not.

2. Check each wheel speed sensor harness for a

short circuit between its wires with a digital
ohmmeter attached to the two terminals at the
harness side of the wheel speed sensor connector.

3. Also, check each wheel speed sensor harness wire

for a short to ground from the connector terminals.

Is there any short circuit in either wheel speed sensor
harness?

Repair the short circuit in the wiring or from a wire to
ground.

Is the repair complete?
Check the continuity of the wiring in both rear wheel
speed sensor circuits between the EBCM connector
and the wheel speed sensor connector on each side of
the vehicle.

•

The left side uses terminals 8 and 9 at the EBCM

connector.

•

The right side uses terminals 2 and 1 at the EBCM

connector.

Is continuity good for both harnesses?

DIAGNOSTIC TROUBLE CODE (DTC) 930 - ACCELERATION SENSOR

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.

Diagnosis

T h i s p r o c e d u r e c h e c k s f o r a m a l f u n c t i o n i n g
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

Fail Action

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.
