T220=Loss of voltage supply to LHC or ECU, normally associated with trucks working on loading docks or very bumpy ground. The ECU relay comes lose and on some occasions falls out. Check power supplies, including fuses first. 99% of the time this is your fault.
Hi Karait,
Thank you for your helpful info, the truck is now working ok though I don't really know what was wrong with it. I had some new control modules, but made no difference, everything that could be changed was swapped from another truck, but still T220. All the wiring was checked and after draining several batteries the code disappeared? the engine started, everything works fine though we still get L247, and sometimes it won't start unless you press the brake pedal. The boss is happy and is trying to source a pathfinder, make my life here in South Sudan a bit easier!
Hi,
According to my papers you may have some expensive troubles here.
This error code applies to LHC module and is identified as the wrong combinantion of the signals on the coding pins.
Particulary - N1:10, N1:28, N1:47 i N1:52
N1 is LHC module, so if you have no diagrams it may be hard to check them.
Anyway - according to the manufacturer, you may have:
- wrong input signal on coding pins
- wrong connection between the modules,'
- wrongly installed engine control module
- engine controle module faulty.
I am afraid, you need someone with Pathfinder.
