### On-Board Diagnostics (OBD) For AM/FM CD Radio

### Diagnostic Trouble Code Mode (T--01) For AM/FM CD Radio

If an error is made while the customer is using the radio, an error message will momentarily appear on the display alerting the customer that an error has been made. The T- -01 mode in the OBD is available to check which error codes have been set and how many times each error code has been set.

1. Press the RCL button one time to display E04 and the number of times the error code has been stored in memory, then use the SEEK rocker button to tab through all the possible error codes (E04, E05, E06).
2. When you are finished checking the error codes, press the RCL button to return to the T- -01 display.
