    Exclamation LR3 Electrical Problems

    I was just curious if anyone has run into electircal problems with their LR3's? If so, what are they, what DTC's are set, what are the symptoms, and what (if any) were your fixes?

    I've heard a case of the cruise control turning itself off, but it turned out to be a faulty switch.

    Default Discovery 3 LR3 Electrical

    Re: the question you posted, I am a service manager for LR in the Caribbean and have had all kinds of electrical problems, mostly related to low battery voltage, then comunication fails between control units.

    If you have a specific problem maybe I can give some sugestions, give me more details, like what simptoms the vehicle is giving and what messages are coming up on the information display in the instrument cluster.

    Best Regards

    It's been a few months since I worked at LR, but batteries were becoming a real problem on the newer cars.

    depending on the climate you live in there can be a numerous amount of electrical problems on the LR3. I live in illinois and we use salt to de ice the roads in the winter. that and rain water leaking in the a pillars can cause so many electrical problems in the wires running along the sides of the car, under the carpet. different electrical connectors under the hood and inside the car becoming corroded. the batteries going bad or blowing up and causing wire harness damage. it just depends on the climate really

    Also if your wife leaves the sunroof open during a rain storm and then there is the wife pours a soda in the console. Havoc is an understatement on both occasions.

    I've not had any issues specific to wiring, but had the alternator was replaced, right after warranty expired of course, and the new battery that was needed due to bad alternator. Also have replaced twice in 120k miles the brake switch under the pedal due to arcing and the tripple code of death.
