MS8070 PT 77 0006 Proper Installation of GM PROMs and MEMCALs GM vehicles equipped with Surface Mount Technology ECCs CARDONE part numbers 77 7165 77 7730 77 7748 77 7749 77 8253 77 8321 ECC failure immediately during installation or shortly after Excessive force applied to circuit board during installation of the MEM CAL or cover Remove cork spacer on top side of MEM CAL if applicable Align notches on MEM CAL with notches on MEM CAL socket VERY GENTLY press down on ENDS of the MEM CAL until clips are against the side of the MEM CAL Press clips inward until they snap into place Install MEM CAL cover and install replacement ECC in the vehicle Perform all tests specified in instruction sheets supplied with each replacement unit If tap testing procedure is performed use fingertips only any other method will cause ECC damage Excessive force to circuit board due to improper installation will VOID THE WARRANTY Application Problem Cause Solution Note W hat s the difference Compare the magnified views of the CARDONE circuit chip and the leading competitor chip Notice how much thicker the J leads surrounding the CARDONE chip are This detail may seem insignificant but it determines whether or not your ECC sale will come back to bite you On a typical ECC board there are about 400 J leads that provide electrical connections to the board If just one of these connections breaks loose the whole ECC can fail And failure is inevitable if you have weak J leads Corrosion heat and vibration constantly attack them causing the solder around the J leads to crack That s why CARDONE goes the extra mile with their soldering process The solid mass created around each lead ensures stable electrical connections even under adverse conditions But CARDONE doesn t stop there Every ECC is 100 full function tested under simulated on the car extremes of thermal shock and vibration Then every connector pin function is verified and loaded to exceed circuit specifications For example if the circuit requires 400 mili amps CARDONE tests up to 1000 mili amps The bottom line is that CARDONE ECCs typically don t come back This saves your time money and reputation So the next time you purchase ECCs or any electronics product for the matter consider your source When you look through the zoom lens CARDONE Electronics stand above the rest ECCs may look the same but at 20x magnification the difference may shock you ABS Modules Air Supply Modules Body Control Computers Cruise Control Modules Engine Control Computers Electronic Struts GM PROM Chips Ignition Distributors Mass Airflow Sensors Power Supply Modules Relay Control Modules Suspension Control Modules Transmission Control Modules Vane Airflow Meters Competitor ECC CARDONE A 1 ECC
