The error code reading sections all seem to be full of typos when they refer to Te rather than Tc, but it's worth noting both the ABS and the PAS instructions specify Tc and E1

(when they're not mistakenly saying Te) and the wiring diagrams show that they're both connected to that pin.

I don't have PAS so I can't confirm if both flash at the same time on my car.

the car is trying to pull more volts through

Errrr.

Voltage is not pulled and is generally constant

(engine speed

/ alternator interactions aside) until the supply cannot meet the power being consumed by it.

Perhaps you're referring to current being drawn from the supply
![](./images/smilies/spacer.gif)
(alternator and battery) and this being unable to fulfil the demand, hence the voltage dropping.

However it's interesting that the pulse starts a couple of seconds after the engine is started and, more importantly, is a brighter pulse rather than the constant light.
![](./images/smilies/spacer.gif)
This suggests that the pulse is surging over 12V and possibly over the expected 14.5V alternator output.

If you have a multimeter handy, it might be worth seeing how the voltage is pulsing.

is it going up or down from 14V?
![](./images/smilies/spacer.gif)
I wonder
![](./images/smilies/spacer.gif)
(and again I'm thinking out loud a little) if that's actually an over-voltage pulse then it could have popped something within the ABS ECU.
![](./images/smilies/spacer.gif)
It could also have popped other ECUs, but that's a concern for later.
![](./images/smilies/spacer.gif)
If the voltage is going too high then the engine ECU could well be struggling to read various engine sensors and thus running the engine poorly.
