Ignition System Diagnostics
- Locate the diagnostic unit and remove its cover. Connect selector cable to socket No. 6. Turn ignition to ON position. Enter control function No. 1 (access codes) by pressing push button one time for at least one second and no more than 3 seconds. To enter control function No. 2, press push button twice for at least one second and no more than 3 seconds. To enter control function No. 3, press push button 3 times for at least one second and no more than 3 seconds.
- Watch the Red LED and count the number of flashes in the 3-flash series. The flash series are separated by a 2.5 second interval. See Figure . Note all codes. Only 3 separate codes can be stored at once. If no codes are stored, the LED will flash a 1-1-1 to indicate the ignition system is operating properly.
- If a fault code is received, refer to IGNITION SYSTEM FAULT CODES table in this article. Depress push button again and check for additional codes. Depress push button a third time, if necessary. If the first code repeats, there are no other codes.
- The diagnostic system memory is full when 3 codes are present. Those 3 codes must be repaired before further codes can be retrieved.
