Torque wrench
Use the factory procedure with the right tightening tool.
Manual-based work becomes much easier when you can torque correctly.

Useful for clips, covers, and trim pieces called out by the manual.
Most manual procedures assume you have a good trim removal kit.
Shop on Amazon →Multimeter kit
Great for electrical troubleshooting and manual-tested circuits.
Electrical work in manuals often needs a meter more than another wrench.

NOTE: Refer to Test Probe Notice.
The following procedures verify good continuity in a circuit.
With a DMM
1. Set the rotary dial of the DMM to the ohm position.
2. Disconnect the power feed (i.e. fuse, control module) from the suspect circuit.
3. Disconnect the load.
4. Press the MIN MAX button on the DMM.
5. Connect one lead of the DMM to one end of the circuit to be tested.
6. Connect the other lead of the DMM to the other end of the circuit.
7. If the DMM displays low or no resistance, the circuit has good continuity.
With a Test Lamp
IMPORTANT: Only use the test lamp procedure on low impedance power and ground circuits.
1. Remove the power feed (i.e. fuse, control module) from the suspect circuit.
2. Disconnect the load.
3. Connect one lead of the test lamp to one end of the circuit to be tested.
4. Connect the other lead of the test lamp to battery positive voltage.
5. Connect the other end of the circuit to ground.
6. If the test lamp illuminates (full intensity), then the circuit has good continuity.
