| The first thing you need to do is read the fault codes in all the computers. Once you read all the fault codes, save a copy of the fault codes, then delete all the fault codes. If you have CAN fault codes, then you should use a scan tool to see if the CAN connections are active. In most computers, groups 125 to 130 may indicate of there is a CAN problem. If you see a "1" then the connection should be good, if you see a "0" then you may have a problem. Look for accident damage, water damage or wiring harness problem where rodents may have had a meal with the harness. CAN messages can also be tested with an oscilloscope. Changing the IC is the last resort, diagnose the problem first. |
