Default 2005 3.3l v6 abs problem

Hi,

I have 2005 voyager and abs warning light is on.

I try read faultcodes but can't get connection in abs module.

I disconnect abs module connector and measure that +12 voltega and ground come in module, i also measure all 4 abs sensors and those are ok

can i remove CAB module and try another module, or is there something what i should know when remove that cab module ???
Or is that so simple that i open those four bolts and remove CAB ???

BR, Timo

I think i found reason why abs lamb is on

I measure those sensors again (with oscilloscope) and notice that left front sensor are more than 500mV lover dc offset than other sensors.

Other sensors have abt 1.5V offset and this left front sensors have abt 700 mV

controller do some selftest when power is on, right?
do anyone know how controller do that selftest in sensors, if controller measure sensors DC offset and that one sersor offset is not correct --> abs lamb is on

BR, Timo
