System DescriptionINFOID:0000000003771164
OUTLINE
The headlamp washer is controlled by each function of BCM and IPDM E/R.
Control by BCM Combination switch reading function
Headlamp washer control function
Control by IPDM E/R Relay control function
HEADLAMP WASHER BASIC OPERATION
BCM detects the combination switch condition by the combination switch reading function.
BCM transmits the headlamp washer request signal to IPDM E/R with CAN communication depending on
each operating condition of the headlamp washer.
Operating conditions (The first time)
- Ignition switch ON
- Headlamps ON (PASS excluded)
- Front washer switch ON at first time.
Operating conditions (From the second time)- Ignition switch ON
- Headlamps ON (PASS excluded)
- Front washer switch ON at fifth time after the first time.
