Before proceeding with diagnosis, the following precautions must be followed:

When using DIAGNOSTIC TESTS for diagnosis, DO NOT skip any steps, or incorrect diagnosis may result. Always perform indicated verification procedure after repairs are made.
When using a jumper wire, ensure either jumper wire or circuit is fuse-protected.
Before disconnecting connector from any control module, ensure ignition is off.
When checking voltage or continuity at any control module, probe connector and/or control module from pin side. DO NOT backprobe connector or module, or probe wires through insulation.
DO NOT cause short circuits when performing electrical tests. This will set additional DTCs, making diagnosis of original problem more difficult.
Use specified test equipment when performing electrical tests.
