  1. can't communicate with engine ecu. Harness 's appear good, terminals also. Someone has to know something...I'm begging...............
  2. Someone chime in and help a guy out!...................................................
  3. MP8......No engine communication. Checked power wires to engine ecm and have 12 volts to both. Checked fuses in top of dash and by clutch pedal. Other ecu's seem to be communicating. I have read where the fuse boxes go bad. Which one's are they talking about? And what are the sympton's?
  4. I have an 08 CHU with MP engine came in loaded with codes and have gradually repaired all but a code for the DPF Regen switch. I found out that it is fused but can't find it. One fuse panel on top of dash and one panel next to clutch pedal. The panel next to clutch pedal has all breakers or relays. I need to know where the dpf switch fuse is. Also would like a diagram of breakers by clutch pedal. ANY help would be appreciated!! Bout to pull my hair out trying to locate this fuse!!
  5. Shows active code Intake Air Temperature Sensor-Voltage Low(Flash Code 2-3). When you do continuity test the sensor wires are on ports 84 and 67 of J2 connector. Book says it should ports 80 and 61. I have checked every wire and connector to get this code out. 4.5 volts to it. What am I missing here?
  6. 2015 CXU 613 Mdrive would not turn over/crank. Transmission showing low air and no neutral on dash. Repaired air leaks on trans tank. Truck now will show neutral and crank. Went into gear when dash showed N. Now it will not go in gear. Accelerates sometimes, but most of the time no respopnse. It does change engine tones when it doesn't accelerate. Lightning bolt on, but dash will not show any codes on guarddog or regen. Has OBD connector and can't get tech tool to communicate. Truck has been sitting about a year. Can't understand why dash will not show any codes and LB still on. If you try and put it in gear, parking light blinks/warning goes off. Borrowed someones obd hd little scanner and it also shows no codes. I'm puzzled as it seems like one issue gets corrected and another pops up. Checked grounds/cables/connectors. Help!!
  7. No codes. Changed cam sensor, checked valve adjustment, fuel pump, return valve, unit pump rollers. Had one cylinder a little weak so replaced one pump and injector. Truck runs and pulls good, just shakes truck at an idle. It's not a big shake and some people don't notice, but you can tell something just is not right. Seems to be worse cold. Merry Christmas everyone!
  8. 2007 Mack Vision Dash does not work at all. If you turn key on mileage numbers cycle through and then "no info". I took dash out of a working truck and it does the same thing. I then took the dash out out of the original non working truck and plugged in to working truck so dash is fine. I have even soldered an extra ground onto pin 35 and no difference. Tightened and cleaned pins and terminals didn't help. You can wiggle any wires and still won't get dash to even flicker. What am I missing?
  9. I have a 2000 Cx613 with variable pitch/geometry turbo and I need the electrical plug for it. Four spade terminals but only three are used...Anyone know what else this plug is used on or where I can purchase without buying the whole harness? Thanks!!
  10. Where can I get the turbo speed sensor and VGT actuator electrical plugs? 2004 CX613...... I am needing the part that would be on the engine harness not the turbo part...Mack wants to sell the whole harness. HELP!!!!!
  11. Now I am getting a MID 128 PPID 440 FMI 1....if anyone can give me an idea of what direction to start I would greatly appreciate!!!!
  12. I have a 2010 MRU613 with a MP7-325M engine is giving regen problems. I have taken filter off and had it cleaned, but still gives a MID 128 PSID 47 FMI 8 code and all I can find is abnormal frequency pulse width or period. What is that and what can I do to repair? Also gives a MID 128 PSID 249 FMI 9 and MID 128 PPID 326 FMI 0 which I know is soot level probably from not regening. This thing is driving me crazy. HELP!!!!
