Diagnostic Codes; Diagnostic Code - 2 Flashes - APRILIA SR MAX 125 ie Service Station Manual

SR MAX 125 ie
Sequence and times must be strictly observed or it will be necessary to repeat the procedure from the
start.
Once the control unit has been programmed, the decoder is inseparably matched with the MASTER
key transponder.
With this link established, it is now possible to encode new service keys, in the event of losses, re-
placements, etc. Each new programming deletes the previous one.
If a service key setting is lost, it is essential to carefully check the efficiency of the high voltage system:
Shielded cap resistance ~ 5000 Ω.
In any case it is advisable to use resistive spark plugs.

Diagnostic codes

The flash indicating the switching to "ON" can be followed by a phase of programmed failure warnings.
That is, the led is off for 2 seconds, and then diagnosis codes are transmitted with 0.5-second flashes.
After the failure code indication, the LED remains on permanently to indicate that ignition is not possible.

Diagnostic code - 2 flashes

When the 2-flash code is detected, carry out the following checks:
- Check if the failure continues after changing key (MASTER key included). If the failure persists with
any key, disconnect the aerial connector from the decoder and check the aerial for continuity with the
recommended tool.
If non-conforming values are measured, replace the aerial.
If no failures are found in the aerial, replace the control unit.
CAUTION
BEFORE PROGRAMMING THE NEW ELECTRONIC CONTROL UNIT CHECK THAT NO FAILURE
CODE IS INDICATED. THIS IS NECESSARY TO AVOID SPOILING A NEW CONTROL UNIT
