Quick test
I have tried the test and my lights light up all the time, just seems to be whilst driving they cut out, does this point to a bulb or igniter failure?

Does anyone know if the CEM controls the sidelights? I have a 2000 V40 1.8 XS and none of the sidelights are working. Hubby says he has checked fuses and bulbs and says he can hear a relay clicking and is wondering if the CEM isnt sending power to any of the sidelights for some reason? (Headlights work if the switch is in position 0 and in headlights on position, both with engine on and off but no sidelights at all.)

Maybe you can try cleaning the electrcial contacts of the light by using some electronic cleaning solvent (not the mechanic type like WD40). I have used it to clean the door light switch to make it work again. |

In my case, I fixed the lights by replacing the relay with about similar one. |

Was it easy to replace the relay on the circuit board? What tools did you use? |

Anyway I used a slightly bigger soldering iron tip (electronics tool) and some solder wick to absorb the solder as much as possible off the relay pins. And then gradually loose the pins inside pcb holes and gently pull the relay out while heat the pins at the same time. Once out of the board, it is easy enough to put a new one on. Good luck. |

Thanks again for the help and confirmation this procedure was correct for my circumstances as above. Picture below shows new relay in the center, darker than the others. http://i52.tinypic.com/wkpjix.jpg |

Well, it happen to one of our fellow volvo owner, who happens to know about electronics too. He soldered new relay in place and it worked. Later, he went to analyse the old relay part. He took it apart. Guess what he found - inside was another, smaller relay, soldered to pins of outer shell. How amazing is that ?!?!
