The following diagrams are derived from information that has been carefully compiled from industry sources known for their reliability and should be accurate. Always verify the circuits be tested with factory manuals whenever possible.
Wire colors vary from module to module as well as year to year. Always identify the circuits that are being tested by their connector pin identification.
Note: When jumping voltage to any circuit always use a fusable link for safety and to protect the components being tested.
Confirm pin identification before jumping voltage to any circuit.
Another alternative is to jump voltage from another fuse that is hot at all times.
All solenoids can be activated through the scan tool.
