LED Indicators On The Side Of The Product Link

(1) Red LED Indicator (Diagnostic Indicator)

(2) Yellow LED Indicator (Power Indicator)

(3) Green LED Indicator (Message Indicator)

The Product Link module has three LED indicators behind a clear window on the side of the unit. These three LED indicators blink in order to convey several types of information to the technician. This information is useful when a computer with the Electronic Technician is not available. The LED indicators do not flash together. Each LED indicator operates independently.

Example of flashes that represents a CID 0254 FMI 12

The red LED flashes in a specific sequence in order to indicate any current diagnostic codes for the Product Link. Each diagnostic code that is being flashed by the red LED indicator has two parts that are separated by a one second pause. The LED indicator quickly flashes a number of times. This is followed by a one second pause. Then, the LED indicator quickly flashes a number of times before pausing for two seconds. The two second pause separates the diagnostic codes that exist. If another diagnostic code exists, the red LED indicator flashes the next code. Count the flashes and refer to table 1. If the red LED indicator is always ON, the unit has failed.
