01331 - Door Control Module; Driver Side (J386): Supply Voltage Too Low
Possible Causes
Fuse(s) faulty
Wiring/Connectors from/to Control Module faulty
Power Supply (Battery/Generator) faulty
Possible Solutions
Check Fuse(s)
Check/Repair Wiring/Connectors from/to Control Module
Check Power Supply (Battery/Generator)
Special Notes
When found in an individual control module, it's most likely a local source (e.g. wiring/connectors).
When found in multiple control modules at the same time, it's most likely a common source (e.g. ground spot, battery, generator).
Intermittent codes are often stored during low outside temperature when the battery capacity goes down and may be ignored.

Should imagine if yours is no comms then similar as to what you have just done for comms in first place ?


Rob.

thank you for that. it looks like its back to basics with the multimeter and contact cleaner. if it turns out to be the central control unit can it be replaced from a doner vehicle and would it have to be programmed. just found out from customer the central locking stopped working some time ago. i have a reciever to test for key fob signal but it would only recieve from about 6in so replaced the battery but it didn,t help. a new fob may be in order. i will keep you informed. thank again for your help. Dennis

tried wake up to central ecu today and could hear it click two or three times but unable to get comms again. double checked all conections but no joy. when i open the drivers door now with the key the alarm goes off strait away and only stops when i turn ignition on. the problem is getting worse. i have on loan a spi & ikeys so i can access pin codes and get a new key cut and new fob to try. getting greyer by the day Dennis

i have replied to the other thread,sounds like a similar problem i was having with a TT which had no spare key,so i programmed one to it but for some reason could not program the remote & when opening the door by the key could not stop alarm until did so with original key ??
