| Fault codes B1087-93 and P0A1A-87 |
|
Hi all,
I asked about these error codes in another thread so I try a new thread to keep it cleaner.
I made work on car in engine bay and after this car gives codes as in headline and refuse to start.
Only from engine bay is a click.
I have only released and reassy. the contact housings in battery box.
I have checked the tiny signal cable and is ok,greased all earth points in wheelhouse,checked fuses and connections to generator(except the tiny single contact housing. I can see it but not reach it)and starter motor. Battery is fully charged.
I have seen that people swap generator but does not seem to solve it?
Any more ideas?
Best regards/johnny

New alternator in place but codes still there.
As I understand it and please correct me if Im wrong:
Signal cabel goes from +pole to battery module which measure the voltage and send result to ECU.
Ecu then send to alternator to charge or not.
Is this how it works?
Text on one code state signal is missing and that should be the signal from battery module or are there other signals needed to send signal to alternator to charge?
