General Information
GENERAL INFORMATION
A large number of ECU controlled systems are used in the CAMRY SOLARA. In general, ECU controlled systems are considered to be very intricate,
requiring a high level of technical knowledge to troubleshoot. However, most problem checking procedures only involve inspecting the ECU controlled
system's circuits one by one. An adequate understanding of the system and a basic knowledge of electricity is enough to perform effective
troubleshooting, accurate diagnoses and necessary repairs.
FOR USING OBD II SCAN TOOL OR INTELLIGENT TESTER
-
Before using the scan tool or tester, the scan tool's instruction book or tester's operator should be read thoroughly.
-
If the scan tool or tester cannot communicate with the ECU controlled systems when you have connected the cable of the tester to the DLC3 with
the ignition switch and tester turned ON, there is a problem on the vehicle side or tester side.
a. If communication is normal when the tester is connected to another vehicle, inspect the diagnosis data link line (Bus + line) or ECU power
circuit of the vehicle.
b. If communication is still impossible when the tester is connected to another vehicle, the problem is probably in the tester itself. Perform the
Self Test procedures outlined in the tester Operator's.
