5. Self-Diagnosis
D The A/C ECU has a self-diagnosis function. It stores any operation failures in the air conditioning system
memory in the form of DTC (Diagnostic Trouble Code).
D There are two methods for reading DTC. One is to use a hand-held tester, and the other is to read DTC
indicated on the heater control panel display.
D For details, see the 2007 Camry Hybrid Vehicle Repair Manual (Pub. No. RM02H0U).
Service Tip
The A/C ECU uses the 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).
