7. Diagnosis
Main body ECU and certification ECU can detect malfunctions in the smart key system when the power
source is in the IG-ON mode.
When the ECUs detect a malfunction, the amber indicator light of the power switch flashes to warn the driver.
At the same time, the ECUs store 5-digit DTC (Diagnostic Trouble Code) in their memories.
D The indicator light warning continues for 15 seconds even after the power source is switched to OFF.
D The DTC can be read by connecting a hand-held tester to the DLC3.
D The smart key system may not operate successfully if a malfunction occurs.
Service Tip
The THS ECU of the '07 Camry Hybrid model uses CAN protocol for diagnostic communication.
Therefore, a hand-held tester and a dedicated adapter [CAN VIM (Vehicle Interface Module)] are
required for accessing diagnostic data. For details, see the 2007 Camry Hybrid Vehicle Repair Manual
(Pub. No. RM02H0U).
