Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Test Equipment
All voltage tests should be performed with a Digital Volt-Ohmmeter (DVOM) with a minimum 10-megohm input impedance, unless specifically stated differently in testing procedure. When instructed to use a jumper wire, ensure an in-line 5-amp fuse is included.
Use 2 Backprobe Sets (07SAZ-001000A) to probe Powertrain Control Module (PCM) connectors when directed by troubleshooting procedures. See Fig 1.
Engine compartment connectors are sealed on wire side of connector. Backprobing engine compartment connectors can cause damage to connector seals and possible connector terminal failure. To test wires, disconnect specified connector and touch tester probe to specified connector terminal. Inserting probe into connector terminal will damage terminal.
