Code Help Needed
Received several codes all at once. Just cruising around, but in some stop and go traffic when I noticed the check engine light was on. 2003 Z has approx 13K original miles. Also engine has long tubes, straight through cats with sensors, dual springs and a tune added about 500 miles ago. Can someone offer up some info on the underlined codes please? Was this just a communication issue with the BCM, or did I develop a ground issue somewhere? Replies will be greatly appreciated.
10-pcm (P0420 HC) - Not listed but I think it is System Low Efficiency Bank 1
AO-LDCM (U1064H) - Loss Of Communications With BCM
A1-RDCM (U1064H) - Loss Of Communications With BCM
A6-SCM B2505H) - Not listed but I think it is Seat Front Vertical Position Sensor Failure
All the best,
slong

The PO420 HC is the only current code.
Basically it's a drivers side catalytic converter efficiency issue.
Loose manifold/header.
Bad Cat or leaking Cat.
Rear o2 sensor weak or needs replacing, check the wiring and connection there too. Make sure nothings touching or melting.
Hope this helps.
