Why is my Pontiac cassette radio displaying a weird error code?
The radio will detect a number of conditions based on the tape being used, and if there’s a problem, one of the following is displayed: “CLN” for clean the heads, “E10” for the cassette being too tight, “E11” for the cassette being broken, and “E13” for communication problems with the unit. Either try cleaning the unit with a cassette cleaner (available at most record and CD stores) or try a different cassette. Also, pressing the “EJECT” button for 5 seconds will clear the “CLN” message. Otherwise have the dealer check it out as there is a Technical Service Bulletin (#649004) which explains all the codes and necessary corrective actions.
