Dokta:
I tested the module switched output to the coil (#1 from XA connector) with a voltmeter and got a steady reading - no pulse or switching. I need to test the inputs to the module - there seems to be 6: cam sensor, crank sensor, coolant temp. sensor, throttle valve switch, CIS data and MAS. Of those it seems to me that the cam and crank sensors are probably the ones that the module can't operate without. I do not find any help in the various manuals I have/have access to, including the M-B CD-ROM. What's your advice?
