9.2.6 Diagnostic information and procedures

9.2.6.1 Visual inspection

-

Confirm Fault Symptom

-

Inspect the easy to access system components to identify whether there is a significant damage or a potential
malfunction.

-

Connector’s connection and vibration should be thoroughly examined. If possible, for vibrations caused
malfunction, it is recommended to use the vibration method.

1. With a finger, gently shook the part that may be faulty and inspect for malfunction.

2. Gently shake the connector vertically and horizontally.

3. Slightly shake wire harness in vertical and horizontal direction.

9.2.6.3 Diagnosis Tester Can Not Communicate with Vehicle

Connect the tester to the data link connector (DTC Data Link Connector) and turn the ignition switch to ON
position. Operate diagnostic unit, if the display shows the communication error message, then the vehicle or the
tester is faulty.

-

If the communication is normal when the tester is connecting with another vehicle, then DLC diagnostic
interface. See Relevant Contents In Control System Inspection for the detailed steps.
