Are you sure this isn't just an old fashioned dead battery? Those starter codes say voltage 5.92v min, which doesn't look good!
That
is interesting to note. If you look at the same two images where that figure is shown, the
battery voltage itself is much higher. In one image, associated variables for P1694, the battery voltage is
12.95, and in the other one, associated variables for P0017, the battery voltage is
12.25
With my limited knowledge, I’m wondering if that’s suggesting that somewhere along the starter circuit, something is drawing an excessive voltage. But what I don’t understand is the meaning of the messages that appear in the starter fields, or similar. To me, they don’t say that the starter itself is dead, but that something in the circuit is not right. But I might be reading it with wishful thinking!
If you notice in the last post with my images from Diagbox, I showed an image and asked if that was where I was supposed to find the control to raise/lower the windows. (I haven’t gone back to see who it was who asked or suggested that I would find a way to raise/lower the windows in there.) Well, I didn’t find any such control
anywhere. What I did find was something much more interesting! And it was the answer to my original question - any way to get around ‘Economy Mode’?
And there is!
Deep, deep down into those menus, I found you
can turn off economy mode,
provided the battery voltage is above 12,51v and it will turn off for a maximum of 60 minutes. I did that, then pressed the up button on both front windows. I was a very happy man! Then I looked for a way to turn on economy mode, rather than wait for the rest of the 60 minutes, but despite trying a couple of different things that looked promising, nothing worked.
The reason for saying this now is because the car system would
not have allowed me to turn off economy mode had the battery voltage been lower than 12.51v. So I’m pretty certain that the problem is not just a case of a flat battery. I’m even questioning why it allowed me to turn it off because one of the readings was 12.25v. It’s possible that I have not remembered correctly the battery voltage required for allowing economy mode to be turned off. And that’s the only explanation I have for why the car’s system allowed me to turn off economy mode.
