Hi i have installed a new battery and it is getting a good charge from the alternator, i did replace the capacitor/ voltage retaining device and had error P1A9C and managed to get some one to register the replacement capacitor and now the error U1134 is there and keeps coming back it says no lin network. no communication with the voltage retaining device. i have checked Marc test procedure 1 on the wiring from stop star ecu for resistance and ok, there is a resistance from the wire from stop start ecu to battery at the negative terminal after that sensor could there be a problem with the battery sensor that is causing error U1134 .
