Problem Symptoms Table

WARNING: This page is about a different car, the 2008 Toyota Tundra. However, it is still accessible from the selected car via links, so may be relevant.

HINT:

Use the table below to help determine the cause of the problem symptom. The potential causes of the symptoms are listed in order of probability in the "Suspected area" column of the table. Check each symptom by checking the suspected areas in the order they are listed. Replace parts as necessary.
The Matrix Table is divided into 2 chapters. When troubleshooting, check Chapter 1 first. If instructions are given in Chapter 1 to proceed to 2, proceed as instructed.
If the instruction "Proceed to next circuit inspection shown in problem symptoms table" is given in the flowchart for a circuit, proceed to the next suspected area in the table.
If the problem still occurs even though there are no malfunctions in any of the circuits, check the ECM and replace it if necessary.
*: When the circuit is defective, a DTC may be output.
