TCL, CEL Warning lights and shuddering.

[Chefy83]

Just brought my first legnum! Got it cheap but it does have a few codes.

Tcl
77 TCL vacuum system or ventilation solenoid
Asc
78 Pressure Accumulator Sensor System
Cel
64 FR Alternator System Terminal
72 Ventilation Control Solenoid Valve System <T / C-A / T>

Pulled those codes and got the details from the forums. White/grey canister on firewall has a few cracks ill glue up... anyone know a part number?

Also felt vibrations that felt like the abs kicking in when drive straight with no brakes applied. Anyone had this?

Thanks for any info

Also have checked altenator and all seems normal... car off 12v on 14v

Suggest checking the solenoid resistance as per the below thread. https://www.ozvr4.com/threads/vr4-legnum-fault-code-tcl.4753/#post-81030

Thank you so much just went to do it and the multimeter has packed it in so will have to wait till tomorrow!

Plugs were full of what in guessing is conductive grease but i was all dried up. Cleaned them a bit and glued up the canister so will try again tomorrow!

Checked the solenoids top one works but resistancs varies from 40 to 18. Bottom one I couldnt get a resistance reading on.... and when i tried to get it to work with a car battery it did nothing. So im guessing they might both be shot.
Now I need to find part numbers....

It's a common issue wth these. Part numbers should be stamped on the back of the solenoids, you have to take them out to see.
