Toyota Venza: Diagnosis System
DIAGNOSIS SYSTEM
1. DESCRIPTION
The ECM controls the cruise control system of the vehicle. The data and DTCs relating to the cruise control system can be read from the DLC3 of the vehicle. If either DTC or CRUISE OK is not displayed on the multi-information display on the combination meter assembly when checking for DTCs, there may be a problem with either the combination meter assembly or the CAN communication system. Use the Techstream to check and solve the problem.
2. CHECK DLC3

3. CHECK INDICATOR

(b) Check that the CRUISE main indicator light illuminates when the cruise control
main switch is turned on, and that the indicator light turns off when the main switch
is turned off. If the results are not as specified, inspect the Cruise Main Indicator
Light Circuit (See page ).
