Vt clubby electrical issues and gearbox flare

[Sstagg2005]

Bit of a list but here we go
Have a 99 VTII Clubsport Gen 3 ls1,
Intermittently the cruise control cuts out, also randomly the ac and the window switches don’t work (great combo) until the car is turned off then they work
Gearbox also seems to flare/rev up as it shifts on light throttle, have had the box rebuilt but not tuned still flares however the box is better ie. no slip and when you’re putting your foot down it’s fine but light throttle it seems like it’s not right
throws codes on the engineering mode diagnostic (T00hc ect.)
T16HC T17HC T19HC
Has thrown these for a while runs but sometimes it starts then dies? Immobliser related but unlock button usually fixes it, sometimes the red light will flash when key is plugged in also, isn’t the metal ring in the barrel meant to stop that?

Have you cleaned/tightened your battery and earth connections?

Yeah no luck

Dash trouble codes
Format is t then code number then history then current some have nu which I cant remember but believe was not used
Eg
t00-- is fuel gauge sender open circuit no history and no current faults
t16h- is abs history codes but no current fault

00 Fuel gauge sender unit — open circuit
01 Fuel gauge sender unit — short circuit
02 Fuel gauge sender unit — intermittent
03 Fuel gauge sender unit — open circuit
04 LPG gauge sender unit — open circuit
05 LPG gauge sender unit — short circuit
06 LPG gauge sender unit — intermittent
08 No serial data from ABS
09 No serial data from BCM
10 No serial data from ECC
11 No serial data from PCM
12 No serial data from SDM
13 No instrument poll from BCM
14 No serial communication
15 No Sub-clock
16 ABS or ABS/ETC fault logged
17 BCM fault logged
18 ECC fault logged
19 PCM fault logged
20 SDM fault logged
21 Trip switch short circuit
22 Trip switch button stuck
24 EE checksum error
25 ROM checksum error
26 Internal fault


sounds like a faulty abs module upsetting the communications
try unplugging abs module for a few days

Replaced abs module already fixed issues I had previously tried playing around with immobliser fixed it for maybe a day and now it’s back to it I’d imagine it’s the bcm

Also any help on gearbox flare what sensors affect transmission

next step would be to closely monitor alternator voltage
you have multiple comms errors
put the parts cannon away
you may have picked up a faulty abs, try unplugging it for a few days
