Ok i have the EPS module i purchased from ebay, and i have downloaded the user manual for the steps for replacement. the only thing i am curious about is step 4:
Connect the WDS or equivalent to the DLC-2.

i do not have this device to hook in and set the command to the computer. how important is this if i still physically align the tires to neutral and then replace? what do the wonderful mazda experts suggest please! i need your help and greatly appreciate it!

 

really? come on guys help me out here!

 

You need to program the new module. It wont work without being programmed. Pain in the **** but common on most Mazda modules now.

 

thank you for the response! so i guess i need to take it to a shop for that or can i rent the calibrator from autozone?
