Wiper System; System Features - Chrysler 300M 1999 Manual

Arming/Disarming - Active arming occurs when the remote keyless entry transmitter is used to
lock the vehicle doors, whether the doors are open or closed. If one or more doors are open, the
arming sequence is completed only after all doors are closed.
Passive disarming occurs upon normal vehicle entry (unlocking either front door with the key).
This disarming also will halt the alarm once it has been activated.
Active disarming occurs when the remote keyless entry transmitter is used to unlock the vehicle
doors. This disarming also will halt the alarm once it has been activated.
System Self-Tests - NOTE: System self-tests can be entered only with the DRB. See vehicle theft
section system test 1A.
NOTE: A powertrain control module from a vehicle equipped with a vehicle theft security system
cannot be used in a vehicle that is not equipped with a vehicle theft security system. If the VTSS
indicator lamp comes on after ignition ON and stays on, the PCI bus communication with the
powertrain control module possibly has been lost.

Wiper System

The wiper system provides the driver with the normal wiper (low and high speeds), intermittent
wipe, wipe after wash, headlamp washers and pulse wipe functions. The driver selects the wiper
function via the resistive multiplexed stalk switch mounted on the steering column. The BCM uses
input signal from the stalk switch, wiper motor park switch and the washer switch to control the
wipe system. The Body Control Module (BCM) then controls the relays and timing functions to
provide the driver selected features.

System Features

Speed Sensitive Intermittent Wipe Mode
There are 6 individual delay times with a minimum delay of 1/2 second to a maximum of 18
seconds. When the vehicle speed is under 6 KMH (10 MPH), the delay time is doubled providing
a range of 1 second to 36 seconds.
Pulse Wipe
The wiper is in the off position and the driver presses the wash button for more than 62
milliseconds, but less than 1/2 second, 2 wipe cycle in low speed mode will be provided.
Park after Ignition Off
Because the wiper relays are powered from the battery the BCM can run the wipers to park after
the ignition is turned off.
Wipe after Wash
When the driver presses the wash button for over 1/2 second and then releases it, the wiper will
continue to run for 2 additional wipe cycles.
Headlamp Washers
The BCM will actuate the headlamp washer relay output for 750ms whenever the windshield
washer are activated and the headlamps are on. The headlamp washers will be activated only for
750ms and then turned off even if the wash switch remains pressed. The headlamp washers will
then be disabled until the wash switch is released and inactive for 5 continuous seconds. The
headlamp washers will not be activated when the wiper pulse wipe mode is used.
The wiper system utilizes the BCM to control the on/off and hi/low relays for low and hi speed
wiper functions, intermittent wiper delay as the switch position changes, pulse wipe, wipe after
wash mode, and wiper motor park functions. The BCM uses the vehicle speed input to double the
usual delay time below 6 KMH (10 MPH) There are three diagnostic trouble codes associated with
