NOTE:

PIDs for the following parts are not available on this model. Go to the appropriate part inspection page.
- CMP sensor (See CAMSHAFT POSITION (CMP) SENSOR INSPECTION ).
- Main relay (See RELAY INSPECTION ).

Connect the M-MDS to the DLC-2.
Turn the ignition switch to the ON position.
Measure the PID value.
- If PID value is not within the specification, follow the instructions in Action column.
NOTE:
- The PID/DATA MONITOR function monitors the calculated value of the input/output signals in the PCM. Therefore, an output device malfunction is not directly indicated as a malfunction of the monitored value for the output device. If a monitored value of an output device is out of specification, inspect the monitored value of the input device related to the output control.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

• You smell fuel, burning insulation, or see smoke.
• Brakes feel soft, pull hard to one side, or make grinding noises.
• The engine overheats, stalls repeatedly, or misfires under load.
• You are missing required tools, torque specs, or safe lifting equipment.
• You are not confident in the next step or safety outcome.
