this weekend i'll have time to fuss with it more.
the SAS is completely kaput. i cannot communicate with it via nanocom. i think the SAS failing may be the cause of some of my woes here, interfering with can bus communication. the chump i bought the truck from, he told me that to "get it out of crash mode" that he would "reach up under the dash and tug on wiring harnesses" because he thought "something was loose" and now i'm wondering if he was yanking on the SAS harness/connector. interesting how it just went tits up all of a sudden.
the 4x4 display does not show any manipulation of the steering wheel, and a complete vehicle reset and unconditional code clear cannot right it. i also blame the SAS for my new TC and ABS warning, and i am NOT looking forward to replacing that guy.
after the HUGE go-round with my "crash mode" woes and all that, i recursively tested the can bus wiring and was unable to locate any faults. i self-diagnosed a faulty IPC, and when i used my nanocom to code the replacement IPC (from ebay) to the truck, the replacement IPC accepted the CCF but the mileage remains at 78k instead of 154k. this is inconsequential to me, as i have no more can bus or IPC faults, and the car hasn't done "crash mode" once since the swap. i will attempt to desolder the IC containing the mileage from my old IPC and into the donor IPC at some point, but until i get the EAS and SAS right, that's a distant priority.
i also wonder, if perhaps there's a specific version of software that should be on each ECU? i noticed that in an attempt to repair the truck, they had replaced the ATC ECU, and possibly others, and i suspect it had a replaced compressor as well... perhaps the software on the EAS computer is expecting an AMK whilst I have a hitachi fitted?
