| Re: speedometer question
… now I am talking what I would do.
You can buy a used IPC and try replacing just the actuator for the speedometer. Is not that complicated to take the IPC apart.
Once you get the IPC out (if you don’t know how ask me how) take the 6 (or so) screws around the edge of the glass trim. Observe that the glass is held in place on the half front of the IPC with some 4 screws (still along the front edge). You don’t need to remove these. Then turn the IPC with the glass down (hold it together since it has no screw) and locate the banner cable on one of the side. Disconnect the cable by pulling away the two hooks at each side (pulling away the hooks will lift the connector), and then lift the back casing (with half of the electronics attached) off the glass face witch will stay attached with the gauges on the glass (the other half of the electronics). The IPC has two PCB’s one that comes out with the backside of the casing and the front PCB (attached to the glass side) housing the gauges actuators, the display strip and the display controller. That banner cable I mentioned makes the connections between the two PCBs.
Now from what I studied (not too much) it appears to me that the back PCB is the one with the memory chip (i.e. where your odometer is stored) while the front PCB only houses the actuators. So theoretically you can just replace the front PCB of your IPC with another one (say from a wreck yard). That would cost you no more than $50 and you don’t have to worry about getting the IPC reprogrammed with the mileage (witch cost money is not a free service). Now this is just an assumption (some how educated), if it doesn’t work you will have to do the programming anyway (but at least you tried). |
