4E-60 ABS AND TCS
DIAGNOSTIC TROUBLE CODE (DTC) 930 - ACCELERATION SENSOR
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
This procedure checks for a malfunctioning
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.
FAULT
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.
