CIRCUIT DIAGNOSIS INFORMATION

How to Use Tester

Connect tester cable to DLC, turn ignition switch ON and try
to use the tester. If communication malfunction appears on
the display, it indicates that the vehicle or tester is defective.
 If communication is normal when the tester is connected
to another vehicle, inspect the DLC on the original
vehicle.
 If communication is still not possible when the tester is
connected to another vehicle, the tester itself is probably
defective.

ECM Control System Troubleshooting

This model uses ECM control system. Most malfunction inspection procedures only involve in checking the
circuits of ECM control system one by one. An adequate understanding of the system and a basic knowledge
of electricity are enough to perform effective troubleshooting, accurate diagnosis and necessary repairs.
