WT-12 < SYSTEM DESCRIPTION > DIAGNOSIS SYSTEM (LOW TIRE PRESSURE WARNING CONTROL UNIT) DIAGNOSIS SYSTEM (LOW TIRE PRESSURE WARNING CONTROL UNIT) Diagnosis Description INFOID:0000000004958171 Description During driving, the transmitter installed at each road wheel transmits the tire pressure information signal to the receiver. The receiver receives the tire pressure signal and transmits it to the low tire pressure warning control unit. The low tire pressure warning control unit judges whether or not the tire pressure is OK based on the tire pressure information signal, and if it judges that the tire pressure is low, it transmits the information via CAN communication to the BCM. After receiving the tire pressure malfunction information via CAN communication, the BCM transmits the tire pressure malfunction information via CAN communication to the combination meter. After receiving the tire pressure information via CAN communication from the BCM, the combination meter illuminates the low tire pressure warning lamp in order to warn the driver. Self-diagnosis procedure 1. Initiate diagnosis mode by short-circuiting the low tire pressure warning check switch to the ground. 2. The blinking pattern of the low tire pressure warning lamp indicates the conditions of the malfunction. NOTE: If the low tire pressure warning lamp is blinking repeatedly at 5 Hz, there is no malfunction occurring in the system. SEIA0745E Flickering pattern Items Diagnostic item is detected when...

EMERGENCY TIRE PUNCTURE REPAIR KIT : Draining INFOID:0000000004958242 DRAINING CAUTION: Never spill the sealant in the tire. 1. Remove tires. 2. Remove the valve core (1) from the transmitter (2) using a core wrench (A), and then bleed air. CAUTION: Cover the valve using a waste cloth to prevent the sealant from being splashed. 3. Separate transmitter from wheel. 4. Install the filling hose to the empty bottle, and then insert the extension hose for draining into the end of filling hose. 5. Insert the hose through the hole, and then prop the tire and further insert the hose until the end of hose sinks under the sealant level. 6. Suck out the sealant by compressing the bottle. NOTE: Place the tire on the proper workbench and hold it higher than the bottle to suck the sealant out easily. 7. Repeat the procedure until the sealant cannot be sucked out while changing the position of hose end. AFTER DRAINING NOTE: The aerosol-type sealant closes off the blowout hole. Therefore, the blowout hole may not be discovered according to the extent of damage, resulting the difficulty of blow out repair. In this case, check the tire pressure thoroughly, and then replace with new tire if the tire pressure decreases. • Remove the tire from the wheel, and then wipe out the sealant on the tire and wheel. • Replace transmitter. Refer to WT-81, "Removal and Installation". CAUTION: Never reuse the transmitter. • Perform the blowout repair if it is possible. Replace with new tire if the blowout repair is impossible. CAUTION: Never discard the tire with the sealant applied. • Treat the sealant drained as waste oil.

CAUTION: • Be careful not to scratch the road wheel during removal. • After removing double-faced adhesive tape, wipe clean traces of releasing agent from the road wheel. Wheel Balance Adjustment If a tire balance machine has adhesion balance weight mode settings and drive-in weight mode setting, select and adjust a drive-in weight mode suitable for road wheels. 1. Set road wheel on tire balance machine using the center hole as a guide. Start the tire balance machine. 2. When inner and outer unbalance values are shown on the tire balance machine indicator, multiply outer unbalance value by 5/3 to determine balance weight that should be used. Select the outer balance weight with a value closest to the calculated value above and install to the designated outer position of, or at the designated angle in relation to the road wheel. CAUTION: • Never install the inner balance weight before installing the outer balance weight. • Before installing the balance weight, always to clean the mating surface of the road wheel. a. Indicated unbalance value × 5/3 = balance weight to be installed Calculation example: 23 g (0.81 oz) × 5/3 = 38.33 g (1.35 oz) ⇒ 37.5 g (1.32 oz) balance weight (closer to calculated balance weight value) NOTE: Note that balance weight value must be closer to the calculated balance weight value. Example: 36.2 ⇒ 35 g (1.23 oz) 36.3 ⇒ 37.5 g (1.32 oz) b. Installed balance weight in the position. SMA054D ROAD WHEEL TIRE ASSEMBLY WT-77 < REMOVAL AND INSTALLATION > C D F G H I J K L M A B WT N O P • When installing balance weight (1) to road wheels, set it into the grooved area (A) on the inner wall of the road wheel as shown in the figure so that the balance weight center (B) is aligned with the tire balance machine indication position (angle) (C). CAUTION: • Always use genuine NISSAN adhesion balance weights. • Balance weights are non-reusable; always replace with new ones. • Never install more than three sheets of balance weight. c. If calculated balance weight value exceeds 50 g (1.76 oz), install two balance weight sheets in line with each other as shown in the figure. CAUTION: Never install one balance weight sheet on top of another. 3. Start the tire balance machine again. 4. Install drive-in balance weight on inner side of road wheel in the tire balance machine indication position (angle). CAUTION: Never install more than two balance weight. 5. Start the tire balance machine. Make sure that inner and outer residual unbalance values are 5 g (0.17 oz) each or below. 6. If either residual unbalance value exceeds 5 g (0.17 oz), repeat installation procedures. TIRE ROTATION • Follow the maintenance schedule for tire rotation service intervals. Refer to MA-5, "General Maintenance". • When installing the wheel, tighten wheel nuts to the specified torque. CAUTION: • Never include the T-type spare tire when rotating the tires. • When installing wheels, tighten them diagonally by dividing the work two to three times in order to prevent the wheels from developing any distortion. • Be careful not to tighten wheel nut at torque exceeding the criteria for preventing strain of disc rotor. • Use NISSAN genuine wheel nuts for aluminum wheels.
