Retrieving Codes
- Locate diagnostic unit and remove its cover. Connect selector cable to socket No. 6. Turn ignition switch to ON position. Enter control function No. 1 (retrieving codes) by pressing push button one time for at least one second and no more than 3 seconds.
- Watch Red LED, and count number of flashes in 3-flash series. Flash series are separated by 3-second intervals. See Figure . Note all codes. Only 3 separate codes can be stored at once. If no codes are stored, LED will flash a 1-1-1 to indicate ignition system is operating properly.
- If a fault code is received, see IGNITION SYSTEM FAULT CODES table. Depress push button again and check for additional codes. Depress push button a third time if necessary. If first code repeats, no other codes are present.
- Diagnostic system memory is full when 3 codes are present. Those codes must be repaired before further codes can be retrieved.
NOTE:
Not all codes listed in IGNITION SYSTEM FAULT CODES
table are used on every vehicle.
