Code 61 with secondary system removed?

[scorp508]

What are the chances the value names themselves are slightly misleading? I don't have a commented/disassembled file to read. I'm working on creating one in spare time, which isn't much lately. . Just disassembling has been slow as I only have a few mins to work on it here and there and that doesn't work well.


According to the FSM, at least in '94...

<41 kPa triggers the electric vacuum pump to run provide more vac if the secondaries are commanded in FULL mode.

<21 kPa triggers DTC 61 in FULL mode.

Any vacuum in NORMAL mode triggers DTC 61. Would they use <101.4 kPa to define any vacuum.

With XFire's conversion we see two values eerily close to two known FSM conditions: (1) start the vac pump if under 41 kPa and (2) set DTC 61 if under 21 kPa.


What if min vac to open meant to start the vac pump and was not related to the secondaries themselves? Just throwing it out there.


A value close to <101.4 kPa somewhere else to define "any vacuum" to set the "any vacuum in normal mode set DTC 61" using XFire's conversion would still be a 1-byte value of 254 or 0xFE hex, while Todd's conversion would require a double-byte value coming in at 302.


On a wild assumption it would be stored near these values, it may not be, I don't see an 0xFE next to these two values in BMCB, but there is a 0xFA (250 dec, 102 kPa) and a 0xF0 (240 dec, 99 kPa) nearby. I don't see a double-byte 120E (302 dec) nearby or anything similar.


Thanks for letting me nerd out a bit.
