Retrieving Trouble Codes
- On all models, count number of flashes from "CHECK ENGINE" light. A trouble code No. 12 will be identified by a flash, pause and flash, flash. A long pause will exist and code No. 12 will be repeated 3 times. See Fig 2 . Each additional code will flash 3 times starting with lowest code to the highest and repeat 3 times.
- If system is operating properly (with no trouble codes), a trouble code No. 12 should exist with ignition on and engine off. This indicates the diagnostic system is capable of storing trouble codes. Start engine and note codes displayed.
- Each individual trouble code will be repeated 3 times and then display the next trouble code. See Fig 2 . Once all trouble codes are displayed, trouble codes will be repeated. After codes are retrieved, remove jumper wire from diagnostic leads to exit diagnostic mode.
NOTE:
Trouble codes can also be retrieved using a "Scan" tool.
