Product questions
What is the 2S/1M configuration on WABCO 4005001010?
This TCS II Basic trailer ABS ECU/valve is for a 2S/1M system: two wheel-speed sensors and one ABS modulator valve. The ECU and single modulator form the basic valve assembly.
How can I check whether 4005001010 is right for my trailer?
WABCO identifies 400 500 101 0 as a 2S/1M Basic assembly for standard trailers; its manual lists a different assembly for dollies and steerables. Provide the trailer VIN or serial number, the existing ECU part number and ABS configuration to verify suitability before ordering.
What voltage and air port connections does 4005001010 use?
The unit is rated at 12 V. Listed port threads are 3/4-14 dry-seal NPTF at port 1 and 3/8-18 dry-seal NPTF at ports 2 and 4; port 3 is a flap exhaust. Check the connections on the existing unit before ordering.
Does an ABS warning light mean the entire 4005001010 assembly must be replaced?
Not necessarily. The field diagnostics guide identifies separately serviceable components and describes fault-code diagnostics for this assembly. Have a qualified technician identify the fault before deciding which part needs replacement.
