• Pressure Sensor Test: Duringthistest,checksare
carried out that verify that the proper response is
received from the pressure sensors during a brake
application.
• Axle Load Sensing Test (Air Ride): The test
has the user verify the expected measurement
of the load pressure sensor, Port 42, for air ride
suspensions. The program provides the reading
of the sensor.
• Mechanical Load Sensor Test (Mechanical
Spring Ride): The test has the user verify the
expected measurement of the spring deection
sensor. The program provides the reading of the
sensor.

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 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chang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.
