Reading and Clearing Diagnostic Trouble Codes

Cruise Control-Code Retrieval:

The codes for the cruise control system are only available for retrieval when the cruise indicator in the instrument cluster is lit, indicating a problem with the cruise control system. Turning the ignition key "OFF" with the cruise indicator lit will clear the codes from memory. To retrieve the codes, follow the steps listed below.
1. Do not turn the ignition switch "OFF".
2. Connect a jumper wire at data link connector between test terminal 17 and ground terminal 12.
3. Observe the cruise control indicator in the instrument cluster.
