Hello, welcome to Just Answer/Pearl. My name is Mike, I will
do my very best to assist you with your question today.

Have you noticed anything staying on?

Anything after market installed on the vehicle?Such as radio,alarm,etc?

 

Customer: replied 3 years ago.


1) Nothing staying on


2) Yes i have installed all in one cd radio dvd and sat nav

Expert:  Mike Kelly replied 3 years ago.
Ok was the factory harness adapter also installed with the cd unit?
Customer: replied 3 years ago.


yes

Expert:  Mike Kelly replied 3 years ago.
Ok,there is a electrical draw on the battery,since the cd unit is after market this would need to be checked first.How this would be done is by using a volt meter and testing the harness for power when the key is off,if power is found there is a short in the harness.Next with the vehicle off each fuse can be tested for power with once you find the one with power the identification of the fuse will tell you what area of the vehicle is creating the draw.
Customer: replied 3 years ago.


I have followed all your advice and checked everything you recommended and the problem has not been rectified. Is there anything else you can suggest?

Expert:  Mike Kelly replied 3 years ago.
The only other suggestion for this type of issue is a short in the ecu,the best way to test the ecu voltage and if it is working properly is by the use of a scan tool with the proper program.
