Automatic Calibration Procedure
HEATING UP THE TRANSMISSION BY USING THE ‘HEAT’-MODE
The ‘HEAT’-mode allows to select forward / reverse while the parking brake is activated, without forcing neutral and will
disable the inching and declutch function. During the heat mode the highest gear is forced – even when the shift lever is
in a lower gear. This combination allows the driver to heat up the transmission by going into stall.
‘HEAT’-mode can be activated in the same way automatic calibration mode is entered (see “ENTERING AUTOMATIC
CALIBRATION MODE”, on page 8). Once “tran” is displayed on the screen, press the M-button once to go into the
“HEAT”-mode. The APC200 will display:
To trigger the ‘HEAT’-mode, push the S-button. The APC200 will display the sump temperature:
This means the actual sump temperature of the transmission is 20°C.
Perform the following steps in order to heat up the transmission:
1.
Make sure the parking brake is active and works properly.
2.
Put the transmission in forward by selecting forward with the shift lever and then accelerates the engine to full throt-
tle.
3.
Keep the engine at full throttle for about 15 seconds and then put the gearbox in neutral by selecting neutral with
the shift lever. Keep the engine at full throttle!
4.
Keep the gearbox in neutral at full engine throttle for about 15 seconds again.
5.
Release the throttle pedal and decelerate the engine to idle.
6.
Go back to point 2 and repeat until the APC200 display shows a temperature above 140°F [60°C]. When the tem-
perature is above 140°F [60°C], the temperature indication on the display starts blinking. Now switch to automatic
calibration by pressing the M-button several times – until the APC200 displays “tran”.
During this warm up procedure, it is possible for the converter out temperature of the transmission to exceed the maxi-
mum limit. This is a consequence of heating up the transmission using this quick procedure. When this occurs, the
engine speed will be limited to half throttle when the APC200 has engine control or forcing neutral when the APC200
has no engine control. To solve this, simply leave the transmission in neutral for a minute and throttle the engine to
around 1300 rpm. This will allow the heat in the converter to be evacuated. After one or two minutes, resume the heat-
ing up procedure if the transmission temperature has not reached 60°C yet.
