DIagnostic code advice
B1016- Loss of communications with PCM
U1064- Loss of communication with DCM
U1096- Loss of communication with IPC
P0442- can not find this code in manual.
Anyone ever see this combination of codes? I thought I seen my lights flicker. I thought maybe something in my power system. Alternator or if it has a voltage regulator. I know my battery is good. I put a Optima red top in about 5 months ago.
Advice would be appreciated. I do not have any warranty on my car. It has 90,000 miles on it.
Check that the gas cap is tight, reset the code and see if it returns.
Turn the key to the ON position, but don't start the engine. Clear any existing messages by pressing
the RESET button. Hold the OPTIONS button down, and press the FUEL button 4
times. This will get you into the CODES section of the DIC. The computer will
automatically display all the codes your car has created. It will cycle through
each code every 3 seconds. Any code that ends in H is a history code (something
that has occurred in the past) but is fine now. Once the computer has finished
going through all of it's codes, press RESET to enter Manual Configuration mode.
It should start with a module and show NO CODES or # CODES
To optionally reset the codes once in manual mode, press and hold RESET until it
displays NO CODES Press OPTIONS to go to the next module. Repeat the steps in
this paragraph until you have reset the codes in all the computer modules. NOTE!! Only reset the codes IF you want to - it is NOT necessary to do this.
