ABS fault code C1232 MONTANA 1998

Montana 1998 front disc brakes, rear drums.
After driving short distanc with low speed at once ABS light turns on and TCS light .
reading with TECH 1 showed code C1232 (left front wheel sensor circuit open or shorted)
we checked the sensor left and right (to compare)front
checked:
resistance -left 1.065 Kilo Omhs right 1.065 Kil Omhs
sensor to ground left NO right NO (on both wires)
so sensors are OK
checked wiring from sensor to connector near left chassis
also ok
so what else can i check ?
took mastercilinder/abs unit away from powerbooster to see where cable
goes but can't see it .
some body nows the location of the EBCM /EBTCM ?
or a other solution to get the light out ?
thanks in advance for reading / give an answer
