YES >> GO TO 5 NO >> Inspection End.INSPECTION AND ADJUSTMENT RF-5C D E F G H I J L M A B RF N O P INSPECTION AND ADJUSTMENT ADDITIONAL SERVICE WHEN REPLACING CONTROL UNIT ADDITIONAL SERVICE WHEN REPLACING CONTROL UNIT : Description INFOID:0000000001712620 MEMORY RESET PROCEDURE 1. Please observe the following instructions at confirming the sunroof operation. NOTE: Do not disconnect the electronic power while the sunroof is operating or within 5 seconds after the sunroof stops (to wipe-out the memory of lid position and operating friction). 2. Initialization of system should be conducted after the following conditions. ? When the battery has been disconnected or discharged.  When the sunroof motor has been disconnected from power.  When the sunroof motor is changed.  When the sunroof does not operate normally (Incomplete initialization conditions). ADDITIONAL SERVICE WHEN REPLACING CONTROL UNIT : Special Repair Re- quirement INFOID:0000000001712621 INITIALIZATION PROCEDURE If the sunroof does not close or open automatically, use the following procedure to return sunroof operation to normal. 1. Turn ignition switch ON. 2. Push and hold the sunroof tilt switch in the forward (DOWN) position until the sunroof is fully closed. 3. After the sunroof has closed all the way, push and hold the tilt switch forward (DOWN) again for more than 2 seconds to re-learn motor position. 4. Initialization is complete if the sunroof operates normally. RF-6SUNROOF SYSTEM FUNCTION DIAGNOSIS SUNROOF SYSTEM System Diagram INFOID:0000000001712623 SUNROOF System Description INFOID:0000000001712624 SUNROOF SYSTEM INPUT/OUTPUT SIGNAL CHART SUNROOF OPERATION  The sunroof motor assembly operates with a power supply that is output from the BCM while the ignition switch is ON or retained power is operating.  The tilt up/down & slide open/close signals from the sunroof switch enable the sunroof motor to move arbi- trarily. AUTO OPERATION The sunroof AUTO feature makes it possible to slide open and slide close or tilt up and tilt down the sunroof without holding the sunroof switch in the slide open/tilt down or slide close/tilt up position. RETAINED POWER OPERATION Retained power operation is an additional power supply function that enables the sunroof system to operate up to 45 seconds after the ignition switch is turned OFF. Retained power function cancel conditions  When a front door is opened (door switch ON)  When ignition switch is turned ON again.  When 45 seconds elapse on the timer.
