DTC Description Possible Causes Action sensor partial short to
ground
Wiring to height
sensor short to other
cable
Height sensor
electrical fault
Height sensor linkage
bent
Incorrect height
sensor fitted height sensor connector (sensor not connected), with respect
to vehicle body. • Voltage to sensor ground connection should
be ~0v • Voltage to sensor signal connection should be ~0v •
Voltage to sensor supply connection should be ~5v All
voltages should be within ± 0.15v. To check sensor operation
on the vehicle: Check for water ingress around the height
sensors, electrical connectors or shaft end. Check for
excessive movement in the shaft in all directions. Raise
vehicle (ideally on wheels-free ramp) until suspension on
corner under investigation is at rebound to gain access to
height sensor. Access may be improved by removing road
wheel. Carefully disconnect the height sensor link from the
upper suspension arm. Monitor the height sensor signal
voltage output for the height sensor under investigation.
Position the sensor arm so it is in the mid position and
confirm that the voltage is around 2.5 volts. Move the sensor
arm over the range ±40° around the mid position and confirm
that the voltage changes smoothly between around 0.2 volts
and 4.8 volts. If voltages are incorrect or do not change
smoothly then replace sensor. NOTE: For angles of movement
beyond ±40°, the sensor signal will clamp to a voltage of
~0.15v or ~4.85v, depending on position of sensor lever. This
is normal. When investigation is complete, refit height sensor
link to upper arm. If any fixings to the height sensor body or
mounting bracket were slackened or found to be loose or if a
height sensor was changed, the vehicle ride height MUST be
re-calibrated. Refer to the relevant section of the workshop
manual for the calibration procedure C1A06-76

General Information - Diagnostic Trouble Code (DTC) Index DTC: Anti-Lock Braking System (ABS)
Description and Operation
Anti-Lock Braking System (ABS)
CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not
guarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle
NOTES:
If the control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the
warranty policy and procedures manual, or determine if any prior approval programme is in operation, prior to the installation
of a new module/component
Generic scan tools may not read the codes listed, or may read only 5-digit codes. Match the 5 digits from the scan tool to
the first 5 digits of the 7-digit code listed to identify the fault (the last 2 digits give extra information read by the
manufacturer-approved diagnostic system)
When performing voltage or resistance tests, always use a digital multimeter accurate to three decimal places and with a
current calibration certificate. When testing resistance, always take the resistance of the digital multimeter leads into account
Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests
Inspect connectors for signs of water ingress, and pins for damage and/or corrosion
If diagnostic trouble codes are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent
concern may be the cause. Always check for loose connections and corroded terminals
Where an 'on demand self-test' is referred to, this can be accessed via the 'diagnostic trouble code monitor' tab on the
manufacturers approved diagnostic system
Check DDW for open campaigns. Refer to the corresponding bulletins and SSMs which may be valid for the specific
customer complaint and carry out the recommendations as required
The table below lists all Diagnostic Trouble Codes (DTCs) that could be logged in the anti-lock braking system module, for
additional diagnosis and testing information refer to the relevant Diagnosis and Testing Section.
