FRONT WIPER AND WASHER SYSTEM < FUNCTION DIAGNOSIS > FUNCTION DIAGNOSIS A FRONT WIPER AND WASHER SYSTEM System Diagram INFOID:0000000004468130 B C D E F JPLIA1261GB G System Description INFOID:0000000004468131 OUTLINE H The front wiper is controlled by each function of BCM and IPDM E/R. Control by BCM • Combination switch reading function • Front wiper control function I Control by IPDM E/R J • Front wiper control function • Relay control function Combination meter indicates low washer fluid warning judged with the signal from the washer level switch. For details of low washer fluid warning, refer to MWI-26, "INFORMATION DISPLAY : System Description". K FRONT WIPER BASIC OPERATION • BCM detects the combination switch condition by the combination switch reading function. • BCM transmits the front wiper request signal to IPDM E/R with CAN communication depending on each WW operating condition of the front wiper. • IPDM E/R turns ON/OFF the integrated front wiper relay and the front wiper high relay according to the front wiper request signal. IPDM E/R provides the power supply to operate the front wiper HI/LO operation. M FRONT WIPER LO OPERATION • BCM transmits the front wiper request signal (LO) to IPDM E/R with CAN communication according to the front wiper LO operating condition. N Front wiper LO operating condition - Ignition switch ON - Front wiper switch LO or front wiper switch MIST (while pressing) • IPDM E/R turns ON the integrated front wiper relay according to the front wiper request signal (LO). FRONT WIPER HI OPERATION • BCM transmits the front wiper request signal (HI) to IPDM E/R with CAN communication according to the front wiper HI operating condition. Front wiper HI operating condition - Ignition switch ON - Front wiper switch HI • IPDM E/R turns ON the integrated front wiper relay and the front wiper high relay according to the front wiper request signal (HI). Revision: 2008 October WW-5 2009 370Z O P
  6. 6. FRONT WIPER AND WASHER SYSTEM < FUNCTION DIAGNOSIS > FRONT WIPER INT OPERATION • BCM transmits the front wiper request signal (INT) to IPDM E/R with CAN communication depending on the front wiper INT operating condition and intermittent operation delay interval according to the wiper intermittent dial position. Front wiper INT operating condition - Ignition switch ON - Front wiper switch INT • IPDM E/R turns ON the integrated front wiper relay so that the front wiper is operated only once according to the front wiper request signal (INT). • BCM detects stop position/except stop position of the front wiper motor according to the front wiper stop position signal received from IPDM E/R with CAN communication. • BCM transmits the front wiper request signal (INT) again after the intermittent operation delay interval. JPLIA1256GB NOTE: Factory setting of the front wiper intermittent operation is the operation without vehicle speed. Front wiper intermittent operation can be set to the operation with vehicle speed by CONSULT-III. Refer to WW-10, "WIPER : CONSULT-III Function (BCM - WIPER)". Front wiper intermittent operation with vehicle speed • BCM calculates the intermittent operation delay interval from the following. - Vehicle speed signal (received from the combination meter with CAN communication) - Wiper intermittent dial position Unit: Second Intermittent operation delay Interval Wiper intermittent dial position Intermittent operation interval Vehicle speed 0 – 5 km/h (0 – 3.1 MPH) 5 – 35 km/h (3.1 – 21.7 MPH) 35 – 65 km/h (21.7 – 40.4 MPH)* 65 km/h (40.4 MPH) or more 0.8 0.6 0.4 0.24 4 3 2 1.2 3 10 7.5 5 3 4 16 12 8 4.8 5 24 18 12 7.2 1 2 6 7 Short ↑ ↓ Long 32 24 16 9.6 42 31.5 21 12.6 *: When without vehicle speed setting FRONT WIPER AUTO STOP OPERATION • BCM stops transmitting the front wiper request signal when the front wiper switch is turned OFF. • IPDM E/R detects the front wiper stop position signal from the front wiper motor and detects the front wiper motor position (stop position/except stop position). Revision: 2008 October WW-6 2009 370Z
  7. 7. FRONT WIPER AND WASHER SYSTEM < FUNCTION DIAGNOSIS > • When the front wiper request signal is stopped, IPDM E/R turns ON the front wiper relay until the front wiper motor returns to the stop position. A B C D E JPLIA0410GB NOTE: • BCM stops the transmitting of the front wiper request signal when the ignition switch is OFF. • IPDM E/R turns the front wiper relay OFF when the ignition switch is OFF. F FRONT WIPER OPERATION LINKED WITH WASHER • BCM transmits the front wiper request signal (LO) to IPDM E/R with CAN communication according to the washer linked operating condition of the front wiper. • BCM transmits the front wiper request signal (LO) so that the front wiper operates approximately 2 times when the front washer switch OFF is detected. G H Washer linked operating condition of front wiper • • Ignition switch ON Front washer switch ON (0.4 second or more) IPDM E/R turns ON the integrated front wiper relay according to the front wiper request signal (LO).
