Ok sorry I didn't tell you what the voltage should be, I do that because a lot of people will tell you what it should be as if they have already checked it instead of giving you the truth so you can actually help. I see that you are not one of those that do that so to the next step.
I need you to pull fuse number 16 it should be 15 amp fuse. This fuse is located on the fuse panel inside the car. Then with the fuse out have you multi meter handy and turn key on engine off and make sure that you have at least 10 volts or more to one side of where the fuse came out of ok.
Now if that is good then you can turn key off and replace the fuse and now locate the gem module behind or near that fuse box. It will have a 14 pin connector and be black and plastic.
Now disconnect it and check for voltage between ground and term 4 (the red wire with white stripe) with key on engine off it should be 10 volts or more. If less then 10 volts then you need to fix that red and white wire as it has a break in it. If all is good there then go to the next step.
Now turn the key off and check resistance between ground and term six (black wire with light green stripe), if less then 5 ohms then we need to look into the module and see if it is bad as it then it probably will be. If more then 5 ohms then that wire has a break and that needs to be fixed. Get back to me with what you find and we will go from there.
