13451120 You must match this!

• 20 total pins, 3 connectors (16-2-2 pins) and dimple top
• NOTE: One mounting point is damaged however the other three will hold this unit in firmly. Review pictures prior to purchase. EBCM is free and clear of rust or corrosion.

You must match your part number and connector pins for proper fitment. GM mad a couple different versions with different inner circuit boards and pin layouts. If you do not match your part number and pin layout you more than likely will get a no communication situation.
• EBCM may require initialization to your vehicle
• Prior to purchase please verify your wheel speed sensors are good or have been replaced and that your wiring harness has no breaks as both of these situations can set trouble codes. 
• You must check your ground strap and have your abs pump tested prior to install. If you have a bad pump and/or wiring it will pop the module immediately causing a "pump runner". This will void your warranty and we cannot take a return.

Module has been repaired and tested by our experienced technical staff! Some of those tests are listed below:
• Solder joints that typically fail have been repaired
• 12+ internal components tested and repaired as necessary
• Relay which typically fails has been replaced  

Please follow below for proper installation of module. If you don't follow these steps you can surge the unit and kill the board. If this happens, we cannot take a return as we repair, power and communicate with all of these units.
• Disconnect the negative terminal of the battery. Make sure the battery connector is not touching the battery post.
• Disconnect and remove module to be replaced. Make sure connector harness is clean and there are no broken wires. 
• Install and connect the replacement module.

• After install clear Diagnostic Trouble Codes and drive vehicle for 10-15 miles.
• Clear codes again and no codes should reappear.
