engine MIL stays on
« on: May 31, 2016, 12:41:13 pm »
I noticed that the engine management light was on on the dash
I found the error code was P1619  Headlamp relay short circuit to ground or open circuit i swapped it with a relay next to it and it still made no difference  No Headlights and no fan  new error code  My trophy is 2013 and has done 9000 miles I have not had any issues with this brilliant bike coming from the German marque after years  good move I thought.
any help with this issue would be greatly appreciated  As far as electrics go I'm a dud bulb   Probably needs a new relay switch I would guess   Oh BTW  this is my first post  so be gentle with me  Will relacing the relay put the light out and remove the error code????
thanks guys or gals

Hi miker80,

First off as a general principal I wouldn't go swapping Relays over
unless you are absolutely certain that they are exactly the same type and configuration.

The most likely cause of DTC P1619 IS either a faulty Headlight Relay,
OR faulty wiring such as a short circuit or open circuit.

On some early Trophy models there was a problem with the wring harness being very "tight"
around the Headstock area, in some cases resulting in wires being pulled out of the end terminations,
such as at the Ignition switch, and Handlebar switches, and this could be your problem.

If the wiring around that area does seem very tight ( check with the handlebars at full lock in both directions ),
then even though your warranty has expired, it might be worth speaking to your Dealer
and mentioning you are aware of this is known problem where some early Trophys were assembled with the harness either too short or not routed correctly, and f yours is one of these Triumph may well agree to put it right at no cost for you.

Otherwise, from what you've said, I would recommend trying to find a friend
who knows about electrics and has a Multi-Meter that can be used to test the wiring.

You're going to have to remove some of the Fairing and covers
to access some of the parts that need testing.

Here are the tests and checks for this problem - go through them in order :

  • Check that the ABS modulator connector is secure.
    ( Multi Plug underneath left hand Control Plate )
  • DISCONNECT the ECM ( Underneath the Headlamp )
  • Test 1 - Check cable and terminal integrity :
    ECM Pin A18 and Ignition Switch Pin 4. Ensure cables are connected clean and tight.
    Rectify any fault found. (  The switched contacts of the Relay are Pins 3 & 5 )
  • Test 2 - Check cable for short circuit :
    Check ECM Pin 18 for short circuit to Ground.
    Rectify wiring fault if found.
  • Test 3 - Check cable continuity :
    Check ECM Pin A18 to Pin 2 of the Headlight Relay continuity,
    and Ignition Switch Pin 4 to Headlight Relay Pin 1 continuity.
    Rectify any wiring fault founnd, if no fault renew Headlight Relay
  • Test 4 - Check cable for short circuit :
    ECM Pin A18 to Ignition switch Pin 4.
    Renew Headlight Relay.
  • Test 5 : Reconnect ECM and check for correct operation.

Good luck !
