Vision V6-3.5L VIN F (1997)
Console: Testing and Inspection
DISPLAY DIAGNOSTICS
OTIS receives Chrysler Collision Detection (CCD bus) messages from the Body Control Module (BCM) for all displayed information except the
compass display. If a dash (-) is displayed, OTIS is not receiving a CCD message from the BCM. To check out the CCD lines and the BCM use
the scan tool (DRB) and Body Diagnostic Procedure.
Temperature
The OTIS displays the temperature range of -56 °C (-70 °F) to 85 °C (85 °F)
Average Fuel Economy
OTIS receives average fuel economy information from the BCM over the CCD lines. If OTIS displays instead of an average fuel economy value, it
is not receiving a CCD message for the average fuel economy from the BCM. To check out the CCD lines and the BCM use the scan tool.
Distance To Empty
OTIS receives distance to empty information from the BCM over the CCD lines. If OTIS displays a dash (-) instead of a distance to empty value,
it is not receiving a CCD message for the distance to empty from the BCM. To check out the CCD lines and the BCM use the scan tool.
Instantaneous Fuel Economy
OTIS receives instantaneous fuel economy information from the BCM over the CCD lines. If OTIS displays a dash (-) instead of an instantaneous
fuel economy value, it is not receiving a CCD message for the instantaneous fuel economy from the BCM. To check out the CCD lines and the
BCM use the scan tool.
Trip Odometer
OTIS receives trip odometer information from the BCM over the CCD lines. If OTIS displays dashes instead of the trip odometer value, it is not
receiving a CCD message for the trip odometer from the BCM. To check out the CCD lines and the BCM use the scan tool.
Elapsed Time
OTIS receives a bus message containing elapsed time information. If OTIS displays dashes, instead of the elapsed time, it is not receiving a CCD
message for the elapsed time from the BCM. To check out the CCD lines and the BCM use the scan tool.
Compass Display
To display the vehicle direction, OTIS processes information from a sensor internal to the module. OTIS is self-calibrating and requires only
variation adjustments dependent upon location. OTIS displays the label CAL whenever the compass is in the fast calibration mode.
If all three of the following conditions listed below occur the vehicle must be demagnetized.
-
Compass portion of the display is blank
-
Temperature portion of the display is OK
-
The label CAL is illuminated
If demagnetizing the vehicle is needed refer to the demagnetizing procedure. After demagnetizing, to calibrate the compass refer to Calibration
Procedure and to set the variance refer to Variance Procedure. If the compass portion of the display is still blank, replace OTIS.
SELF-DIAGNOSTIC TEST
1. With the ignition switch in the OFF position simultaneously press the C/T and STEP buttons and hold.
2. Turn ignition switch ON, then release C/T and STEP buttons.
3. OTIS lights all segments on the VFD for 2-4 seconds. Check for segments that are not illuminated.
4. If OTIS displays PASS, the module is OK.
5. If OTIS displays FAIL, replace the module.
6. If OTIS displays CCD, check for an open or a short in the bus communication wires.
7. Press the C/T or the STEP button to exit self-test.
