The Single Board Engine Controller (SBEC) or Powertrain Control Module (PCM) is located in engine compartment, to the left of the battery. For more details, refer to Section 4 .
If equipped with the A604 automatic transaxle, the transaxle control computer is located in the right front of the engine compartment, mounted to the inside of the fender. For more information, refer to Section 7 .
The body control computer, if so equipped, is located inside the passenger compartment, behind the right side kick panel.
The Anti-lock Brake System (ABS) control computer is located depending on the year of the vehicle as follows:

  • 1988-90: The Bosch III ABS controller is located behind the rear seat bulkhead trim panel in the trunk.

  • 1992-95: The Bendix Type 6 ABS controller is located on the inner right-hand fender in the engine compartment.
If the vehicle is equipped with automatic load leveling or automatic air suspension, the control computer is located behind the right side trunk trim panel. ..... hopes this helps......

this sort of problem is difficult owing to the complexity of modern vehicles and i would suggest you take it to a dealer as without my head under the bonnet its very difficult ,you have changed the regular items that could cause it so its possible you have a malfunctioning ECU fault and without the correct software to read the problem then no chance

Where is my Oil Filter on my 2007 Hyundai Sonata

Hi, I'm not at all familiar with your vehicle, however I had a similar stressful experience with a Smart car. I looked everywhere for a cannister filter when it is in fact a paper insert. Try looking for possibly a largish black plastic domed top with a huge 24mmish sized bolt head on its top.
Ask your local parts supplier what type of filter is listed for your model?
Hope this helped? if yes please press the blue button for my FREE effort!
