  • Found separated bonding wires but I'm unable to repair these, these are aluminum and I can't solder aluminum. this will need to be repaired by someone more qualified than I. Customer holding off on repairs, this is a very common issue apparently and there are options for re builders on ebay. if anyone can recommend one that is reputable please share a link.

    This is why I stick to vehicles that still had ash trays... Because these days we are repairing nothing but sensors, ECU's, PCM's, modules, or searching for a "possible" short though 2000 miles of wires wrapped in a harness that snakes behind every panel and hole the vehicle has. The way I see it except lighting and a starter, the only wires an engine requires is 8 ignition, one coil, and an easily replaceable clipped on cap and rotor.

    After resoldering those pads did it work?

      Can't solder them, at least not with the equipment I have... The pads are aluminum or something, I forget

    The wires that conduct the current used in the control unit are silver wires that work with ultrasonic waves, but how can they be obtained and how are they connected?

      Aluminum and gold are the most common materials for bonding wires. Even copper is considered exotic.
      The thicker bond wires that fail are aluminum. The thin gold wires are reliable.
      Wire bonding is done with a thin probe attached to a ultrasonic transducer. Wire bonding machines are several thousand dollars and up -- not wildly expensive but not something a hobbyist would be buying.
      You can try to replace the wire with something solderable -- copper or wire-wrapping wire. But you'll find that removing the silicone gel is very likely to break the almost-invisible gold wires on adjacent pads.
