Re: 2003 Cadillac DeVille 1301 codes

I pulled my codes today and I am getting numerous 1301 codes like LRD IPC and DDM what could this mean
========================
the complete code will have a letter before the number -

B - body -
C - chassis -
P - powertrain -
U - network -

always include the definitions along with the complete code -

--------------

LRD = Left Rear Door -
IPC = Instrument Panel Cluster -
DDM = Driver Door Module -
