I pulled a code 26: Quad driver module "A" Circuit, and code 52: CAL-PAK faulty,missing or installed wrong. Do our cars have prom chips or Mem-Cals? Either way, I'm guessing this is some sort of computer issue.. the car still runs normal, but the SES light is going on and off. Anyone have any experience with these codes before?

I've got the same problem. Our ECU'* do have a mem-cal. I don't know if it'* a faulty ECU or not.. I can never get mine to give me codes when it'* got the SES light on, and when it'* off, it says there aren't any codes. I am curious about the outcome, also.

I think that the hybrid PCM'* have a eprom. The ODB I have the MEM-CAL

whatever you do dont try to swap the ECU 1st 9 times out of 10 that isnt the problemn

I reset the battery yesterday, these two codes are fresh. Could the Quad driver module be my boost control solenoid if I've done the bypass mod? I haven't messed with any electronics on it, just the vacuum lines.
