Do you have a digital volt meter and a test light?

Customer: replied 10 months ago.
i do
Expert:  kalamykid replied 10 months ago.

Connect your test light to a good body ground and test each and every fuse on both sides of the fuses and see if you have 12 volts on both sides one side or no power at all with the ignition switch in the run position. Please tell me what fuses have no power and what fuses have power just to one side.

Expert:  kalamykid replied 10 months ago.

You will need to test all the fuses in both fuse boxes.

Thank you for your help. Discovered low transmission oil. Topping up now. Sorry for inconvenience.

Low trans fluid levels will not cause the abs light to come on.
