READOUT OF THE OIL LEVEL SENSOR

Your Transmission may be equipped with an electronic oil level sensor (OLS), either as an option or as standard equipment.  The OLS is designed to measure transmission oil level only when a specific combination of operating conditions exist:

     engine must be at idle
     NEUTRAL must be selected
     zero output speed
     transmission oil must be within a "normal" temperature band
     once the first four conditions are met, a "waiting" period must pass (to facilitate        consistent oil drainback) before oil level measurement may begin.    
     *NOTE* Have vehicle in a level position prior to begining this procedure.

 
OLS WITH PUSHBUTTON SHIFTER

To enter OLS readout mode (after meeting the conditions noted above), simutlaneously press the UPSHIFT and DOWNSHIFT arrows on the shifter.  If the five conditions noted above are present, the display will immediately enter the reading mode.  If the "waiting" period has not elapsed, the left digit of the shifter display will become a "chasing" digit and the right digit will count down from 8 to 1 until the waiting period is complete.

After attaining the reading mode, the display will flash "OL-OK", "LO-01", "HI-02", etc., where the suffix "01" or "02"indicate the volume of oil (in quarts) ow or high.

At any time in this sequence, simultaneously pressing the UPSHIFT and DOWNSHIFT arrows directs the ECU to enter the transmission diagnostic mode.  D, N, or R may also be selected on the shifter at any time- the OLS mode will abort and normal transmission will commence.  Shifts are not inhibited.

OLS WITH LEVER SHIFTER

To enter OLS readout mode (after meeting the conditions noted above), press the Diagnostic button (small button below the MODE button).  The oil level checking function and display readout are the same as for the pushbutton shifter.  Similarly to the pushbutton shifter, depressing the Diagnostic button a second time will direct the ECU to the transmission diagnostic mode.  Likewise, selecting a range on the shifter at any time will abort OLS mode and immediately begin normal transmission operation.
