Sounds like that book has some good info in it. It there anything in there that could make sense of this trans datastream portion of the hac?
I was thinking it might be something used in the diesel engine TCM.Code:L53F3 FDB $0010 ; 11, MALFFLG6, ERROR WD 6
;
; b7 1 = ERR 57. (not used)
; b6 1 = ERR 58, XMISH TEMP HI
; b5 1 = ERR 59, XMISH TEMP LOW
; b4 1 = ERR 61, TURBO BOOST SENSOR HI
;
; b3 1 = ERR 62, TURBO BOOST SENSOR LOW
; b2 1 = ERR 63, BARO SENSOR HI
; b1 1 = ERR 64, BARO SENSOR LOW
; b0 1 = ERR 65. (not used)
