    RXP 2004 Continuous warning beep and other faults

    Hi, out of the ski tonight in the rough and it now has a continuous warning bleep even with the DESS key off.

    Other faults, first the stop/start button failed to work and as soon as you put the key on the DESS post it would crank and fire up. To stop the engine you had to pull the key off. Stop button failed to work.

    P1690 stored (VTS) but VTS still functioned correctly.

    Then all buttons on the left (VTS, Mode, Set, Start/Stop) failed to work at all.

    Disconnected the battery and re-connected it - Same

    Any ideas where to start looking?

    Thanks BVG

    You got a short in the starter solenoid, or in the wiring or the switch to the starter solenoid...

    Thanks guys, I now have a starting point to check from. Any other tips?

    You may have a shorted out DESS post, or water in the connector to the DESS post. Check it out first.

    A shorted dess wouldn't cause the starter to turn. Unplug the plug from the solenoid an check for voltage between the plug. You should NOT have any voltage there. If you do your starter switch is shorted closed...

    Yeah, after thinking about it, you are probably right. However, he will need to pull the plug, then put the key on the post and measure for voltage. (he wouldn't see voltage without the key on post...)

    You are correct sir.

    I checked the wiring Diagram and the start switch runs right into the ECU (yellow-red wire) and the MMPM (purple wire). The ECU then supplies a ground and the MMPM supplies 12VDC to the starter relay. So if the relay,switch or a wire isn't shorted, it may be a bad MMPM. You can check the continuity of the starter switch itself (normally open) by placing an Ohm meter between pin (B-19) on the ECU and pin (2-23) of the MMPM. It should read open and continuity when the switch is pushed.

    Guys, thank you all for the input. I will be doing these checks just as soon as I can. Went to bed last night worried it was broken bad. Woke up to these posts and feeling good, some real positive steps to do to check out what the fault may be.

    Thank you all.
    BVG

    Found the fault(s).

    Fault 1 - The start / stop switch had water ingress and corroded the contacts. Done the checks as suggested by Alpheus - 12v at the trigger wires to the starter solenoid at all times the DESS key was plugged it. Removed the switch gear on the left hand side of the handlebars. Probed the switch wires with the looms unplugged from under the hood - Had continuity, cut the orange waterproofing open from around the switch and bingo, corrosion causing the short and causing the starter motor to run / crank as soon as the DESS key was plugged in.

    Fault 2 - The continuous beep even without the DESS key plugged in - Caused by corrosion in one of the two grey 6 pin plug connectors that feed the dash / left hand handle bar controls. The buzzer was picking up a live feed from the corrosion and sounding all of the time.

    Solution for both the above is a new helm loom to be installed.

    Thanks for the help and advice chaps.

    Regards BVG
