I can not understand why it is so hard to find any online Fault Codes information for the 1992 Mercedes 500SL 16 pole/pin test module.
Any help/links documents to find these fault codes and explanations of codes found for diagnostic testing would greatly be appreciated.
I've attached a link I found on BenzWorld for the diagnostic code manual to use with the LED blink tester.
