I need wiring diagram of EW160B and service manual. Can anybody help plz.
hi TVA
Thanks for your support uptill now.
I need more help
I am getting follwoing errror codes;
i. 187 SID 23 19
ii. 140 SID 23 19
iii. 128 PID 102 4
Moreover, i can not start my engines as IECU shows Communication fault. Guide me what should I do??

Two top ones - j1939 ubnormal update rate, 187 - can’t find, 140 - instrument cluster. On these beside checking wiring and powers/grounds need to measure resistance in fast network, gonna need specs out of manual But usually it’s 60-70 ohm
The bottom one - intake manifold pressure sensor short to ground.

Hi
No help yet .
May be I check
J1939 Terminating Resistor
Can you please let me know location for Volvo
EW 160 B excavator J1939 Terminatating resistors. I did find one its beside the fuse box but dint find the other.

Another thing, this being Volvo wiring - test your powers and grounds with a load. Ther may be one
or two strands left in that wire and will still show power or ground and continuity on multimeter, but as soon you put the load on it, will have excessive resistance. Do not use the multimeter but good wattage light, you can go as far as 55 watt. Got to warn you though! Unplug everything but the fuse on the wire you testing so you will not burn your controller, and do not keep your test light for long - you can burn the thin wires. Just touch the connector and if you got bright light - circuit is good, if it’s dim - you got one or two strands left, and with a big bulb even those will finally burn up. Try to backprobe so you will not arch damage the business end of connector.
I already feel guilty about suggesting this!!!

Thanx I will try and let you know. Today i tried to check resistance on my cruise control padal. It's the TWO way padal under operator RIGHT foot which moves the machine back and forward . I measured with the battery discnoticted i dint have any resistance on both sides " connector side and the padel sensor side even by the padel movement .
I tried to measure voltage on it . I do get ground on the connector to the body opposite side of the padal sensor "but dont have any voltage on it ". Can this be a cause ??
I forgot to mention I disconnected TECU , VECU and IECU and the padel sensor but still the machine starts on just engine ECU and it moves back and forward but by depressing the padel sensor the machines hydraulics take lot of load. Dosenot work on auto mode " just works on manual mode .
when i re connected the TECU nothing changed dint have any error codes. but as soon as I connected the VECU the error code of no communication between ECUs disappeared but the rest two codes
128 pid 91 9 and 128 pid 72 3 reappeared.

No the IECU does not indicate active or stored it just displays the code .I opened the cruise control padal cleaned it . I am not getting any continuity from sensor wires. I checked the continuity from sensor plug wire to the wire in fuse compartment its ok but no voltage on it .
Ground lead ok. no resistance on cruise sensor .

What's the problem with your machine
I think you having more serious problems the this pedal sensor. Just unplug it for now and fix the main problem.
