Toyota Sienna Service Manual / Cruise control / Cruise control system / Fail-safe chart

HINT: If the following conditions are detected while the cruise control is in operation, the system clears the stored vehicle speed in the ECM and cancels the cruise control operation.

Vehicle Condition	Auto Cancel Condition	Re-operation Condition
CRUISE main indicator light blinks	There is open or short in stop light switch circuit There is problem with vehicle speed signal There is problem with throttle position sensor and motor	Turn cruise control main switch on again
CRUISE main indicator light blinks	There is problem with input circuit of stop light switch circuit There is problem with cancel circuit	Turn ignition switch off then on again
Cruise control is cancelled (The indicator light remains on)	At the following conditions, the stored vehicle speed is maintained. Vehicle speed is lower than low speed limit (approx. 40 km/h (25 mph)) while running with cruise control on VSC operates	Push cruise control main switch to + (ACCEL)/RES (RESUME)
	Vehicle speed is lower than stored speed by approx. 16 km/h (10 mph) or more	Push cruise control main switch to - (COAST)/ SET
