TCL fault code 77

[dantfer]

77 TCL vacuum system or ventilation solenoid keeps showing on flashy dash but no tcl light. my tcl does light up on ignition so not sure why? only code coming up

Have you reset the codes to clear it? It might just be an old code.

[dantfer]

yeah i did and it it disappeared. but now im stuck with a load of codes :(

[Nick Mann]

You cleared your only code and now have loads? What do you have now?

[dantfer]

Turns out i seem to have cracked both rear abs rings and now i have mainly 23,24 codes for tcl,tsc abs and 23 ayc and 82 so im going to get a pump switch and replace the rings but the vaccum solenoid keeps reappearing and they give the correct resistance so im not aure what ot could be, ive changed the lines so they arnt cracked or split
