Operating System Messages
General Information
The VIC monitors 12 vehicle operating systems. If a fault is detected, an area of the vehicle display outline will light-up and a message will appear. To
alert the driver, an audio signal warning (beeps) will occur the first time the message appears.

DOOR AJAR/LIFTGATE OPEN
These messages are displayed when the door jamb or liftgate ajar switch is grounded (closed). For the left front door only, whenever the door is
open and the vehicle speed is greater that 10 MPH, the TONE-OUT will sound. This same warning will be enabled whenever the right front or
either rear door is open, and the vehicle speed is greater that 2 MPH.
REAR LAMP FAILURE
Message is displayed when lamp outage module input is open for 1/2 second. This display is latched on until the ignition turns OFF. If a bulb is
replaced the ignition must be turned OFF to make the message clear.
TURN SIGNAL ON
Message is turned on if 1 mile has elapsed with turn signal on.
CHECK BATTERY
Message is turned on when the ignition voltage is not between 11.5 and 15.1 volts. The reading is checked every 15 seconds for an over or under
battery voltage. It takes 2 consecutive 15 second average readings to turn the message on and 1 to remove it. The message can be turned on
anywhere between 15 and 30 seconds and removed within 15 seconds.
Fluid Level Messages
FLUID LEVEL MESSAGES
The module monitors the following 3 fluid levels:
-
Engine oil level
-
Washer fluid low
-
Engine coolant level low
CHECK OIL LEVEL/OIL LEVEL SENSOR BAD
The module will test the oil sensor input immediately after ignition ON. If low oil is detected during the test or the oil level sensor is bad, the VIC
will display this message. The engine on the vehicle outline will also be illuminated. Ignition must be OFF for 1 minute before the oil is checked.
If the fault is found, the message will stay on until the ignition turns OFF. Unless the ignition has been off for one minute or longer and the oil fault
fixed, the fault will appear again on the next ignition ON.
WASHER FLUID LOW/COOLANT LEVEL LOW
The module will test the washer and coolant input immediately after ignition ON and determine if there is a fault. Thereafter the inputs are checked
every 1 second. It takes 30 consecutive low averaged samples to determine the washer or coolant is low. It takes 15 consecutive low averaged
samples to determine the sensor is bad. The washer and coolant messages are latched until the ignition turns OFF.
