1993 Saturn with code 26 & 32

Check engine light comes on intermittantly and I scanned to get codes 26 (quad driver fault) and 32 (EGR system).

I cleaned and then replaced the EGR valve yet the codes are still there. From what I've been reading, the quad driver is in the ECM and most people replace the ECM to fix this. Are there any other steps for troubleshooting this (i.e. check the solenoid) that I can do before replacing the expensive ECM?
