1997 P38 DSE. I have recenty been getting EAS,ABS,SRS,TC messages come up on dash and speedo stops working. The fault usually come up whilst driving, if I drive on, they usually disappear in about half a mile.
The alternator has been replaced (after the messages started) as its output was a little low. Now have 14.2/14.4v at the battery when the engine is running.
I have a Nanocom and it displays a reading around 13.5v on the instruments settings of the Nanocom and 14.2v as an input on the gearbox ECU. It looks to me that the gearbox ecu and becam share the same earth so I don't think it is this. I haven't had the fusebox apart, but there is no smell or signs of shorting.
The battery turns over the engine like a good un, but a load test results in a reading of 12.4v I've read that anything below 12.5 can be a problem on a P38. Could it be this despite the alternator presenting 14v?
Anyone had this problem and found the cause?
