System Check-out
With the brake system fully charged with air, fully apply the
service brakes and hold. Remove and apply ignition power.
Does each PMV (modulator) exhaust air in the following
pattern (SA Right, SA Left, DA Right, and DA Left)?
Does each PMV exhaust air once per pattern (not twice)?
Does the pattern of PMV exhausts repeat?
Did the ABS indicator lamp illuminate for a period of
approximately three seconds and then extinguish? (Assuming
no diagnostic trouble codes are present.)
Verify that only the green LED is illuminated. Any red LEDs
that are illuminated indicate a diagnostic trouble code.
With the power off, remove the 30 pin connector from the ECU.
Key vehicle on. Does the ABS indicator lamp illuminate?
Does the ABS indicator lamp illuminate as required when ABS
is disabled due to a fault in the system?
(Where an off-board diagnostic device is available for testing.)
Is the ECU communicating over the J1587 link? (The J1587
link may not be connected to the ABS ECU.)
Is the correct ECU installed? (Verify ECU part number)
Are all Wheel Speed Sensors (WSS) wired properly to the
ECU? (for example, SA Left WSS to SA Left WSS ECU input)
Open each wheel speed sensor connection, making sure the
correct component and location are displayed on the LEDs:
Steer Axle Right Sensor
Steer Axle Left Sensor
Drive Axle Right Sensor
Drive Axle Left Sensor
Do all WSS have acceptable signal output (0.25 VAC @ 0.5
RPS)?
Are all PMVs wired properly to the ECU? (for example, SA
Left PMV REL to SA Left PMV REL ECU input)
Open each modulator connection making sure the correct
component and location are displayed on the LEDs:
Steer Axle Right Modulator
Steer Axle Left Modulator
Drive Axle Right Modulator
Drive Axle Left Modulator
If the vehicle is equipped with a retarder relay, is the ECU
confi gured to control the relay?
Does the ECU perform ABS properly on each wheel? Where
a test track or similar area is available, test drive the vehicle
and make sure ABS is operating correctly.
