Five-step Troubleshooting

1. Verify The Complaint: Turn on all the components in the problem circuit to verify the customer complaint. Note the symptoms. Do not begin disassembly or testing until you have narrowed down the problem area.

2. Analyze The Schematic: Look up the schematic for the problem circuit.

Determine how the circuit is supposed to work by tracing the current paths from the power feed through the circuit components to ground. If several circuits fail at the same time, the fuse or a ground is a likely cause.

Based on the symptoms and your understanding of the circuit operation, identify one or more possible causes of the problem.

3. Isolate The Problem By Testing The Circuit: Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure is the key to efficient troubleshooting.

Test for the most likely cause of failure first. Try to make tests at points that are easily accessible.

4. Fix The Problem: Once the specific problem is identified, make the repair. Be sure to use proper tools and safe procedures.

5. Make Sure The Circuit Works: Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If the problem was a blown fuse, be sure to test all of the circuits on the fuse. Make sure no new problems turn up and the original problem does not recur.

2. Turn the ignition switch ON (II).

3. Make sure the HDS communicates with the vehicle, if it doesn't, troubleshoot the DLC circuit.

4. Enter the BODY ELECTRICAL then select the TEST MODE menu.

5. Check for DTCs with the HDS.

6. If any DTCs are indicated, note them, and go to the indicated DTC troubleshooting.

1. Check the inboard boot (A) and the outboard boot (B) on the driveshaft (C) for cracks, damage, leaking grease, and loose boot bands (D). If any damage is found, replace the boot and boot bands. 2. Turn the driveshaft by hand, and make sure the splines (E) and joint are not excessively loose. 3.

 Additional Safety Precautions

Never let passengers ride in the cargo area or on top of a foldeddown back seat. If they do, they could be very seriously injured in a crash. Passengers should not stand up or change seats while the vehicle is moving. A passenger who is not wearing a seat belt during a crash or emerge
