Hi. Im having fun getting to know and fix on the car during my vacation - and taking advantage of having the car in front of the house where we are - not possible in NYC.
I have had an intermittent ABS fault since I had the car. Read all the posts and checked the relay in the trunk - no signs of dry contacts but resoldered them all anyway.
The issue is odd - the fault only occurs when i put the ignition on but dont start the car straight away. If it start the car immediately i almost never get it. Often it clears after starting.
The car does like to turnover a lot (need to check the crank shaft sensor) particularly when hot but not only. The battery voltage takes a hammering and it seems if i rev the car to get the battery voltage up after starting i rarely get the alarm
I charged the battery over night and i also left the charger on - and turned the ignition on - and the fault still occurs. I measured the voltage at the relay and its 12.4volts. The relay is making contact and passing the 12.4volts through it
Any ideas what this could be would be appreciated
