Volvo On-Highway Vehicles - Bendix ABS Fault SPN 807 FMI 13 Blink
code 19-4
The new Central Pressure Control (CPC) system has changed the way that the ABS chuff test is
performed. On initial key on the ABS goes through a pneumatic chuff test where it activates the
ABS modulators. The second portion of the test activates once the driver applies the service brake.
The system then performs a pneumatic and electrical test that monitors system response while
activating modulators such as Trailer Pressure Modulator Valve (TPMV). This test is to verify
electrical components along with the pneumatic system pressures and exhaust are working
correctly.
There have been a few trucks that have not passed the chuff test due to hose configuration and the
software monitors not allowing for system or driver variables. This ABS software and hardware
change will address both.

Relocate the vent by removing the mushroom vent from ATR6 valve control port and run 3/8 line

After the configuration is complete, the configuration window will be closed and another
connection to Central Systems will be made in order to send a confirmation that the
configuration has been completed successfully.
Once the configuration has been completed verify that the system air is fully charged. Apply ignition
power and wait 30 seconds.
1. Use Bendix ACom Pro Diagnostic Software or ACom Diagnostic Software V6.7.2.5 (or higher) to
clear the active pressure sensor DTC.
2. Carrying out the demand pressure sensor initialization procedure which involves applying service
brakes of 90 psi or greater for three (3) seconds (while stationary).
Once this procedure is carried out successfully, if there are no other active DTCs,
the ATC/ESP indicator lamp will no longer be illuminated.
