• Mechanical Load Sensor Test (Mechanical
Spring Ride): The test has the user verify the
expected measurement of the spring deflection
sensor. The program provides the reading of the
sensor.
• Customer Scratch Pad: The tester is requested
to input data into the fields displayed on the screen.
This data will be stored in the ECU and also can be
stored to a file on the computer or printed out for
reference.
8. Where a safe location (e.g. restricted access area or
test track) is available, it is possible to road test the ABS
function by making an abrupt stop from a vehicle speed
of about 20 MPH to check for proper function. The
wheels should not enter a prolonged lock condition and
ABS function should be audible. It is the responsibility
of the technician to perform this test in a safe location.
ABS WIRING
All connector leads of the Bendix ® TABS‑6 ™ Adv MC
module pigtail harness are weather sealed at the connector
interface and are clearly labeled for proper installation.
Bendix provides over‑molded versions of the TABS‑6
wiring harness and Bendix recommends that the complete
harness be replaced if corrosion or damage occurs.
When troubleshooting ABS wiring, some general rules
should be followed where applicable.
1. Check all wiring and connectors to ensure they are
secure and free from visible damage (e.g. cuts,
abrasions, etc.).
2. Check for evidence of wire chafing due to poor routing,
or poor securing of wires.
3. Check connectors for proper insertion and locking.
4. Verify that the connector pins are properly greased with
a non‑conductive electrical grease compound.
5. Connector terminals must not show signs of corrosion
or exposure to the environment.
6. Never pierce wire insulation when checking for
continuity.
7. Do not deform individual pins or sockets during probing
with a volt/ohm meter.
8. It is strongly recommended that all wiring harnesses and
sensor leads are properly secured at least every 18 inches.
9. Apply a moderate amount of non‑conductive electrical
grease to each connector pin before reconnecting.
