USING THE CDM TO RETRIEVE DATA FROM THE ON-BOARD COMPUTER
1. Turn the CDM on and press and release the function button until desired function appears.
2. Position the CDM under the rear of the vehicle so that it is aligned directly behind the on-board com-
puter (Figure 20-12). Make sure the CDM infra-red LED receiver is pointed at the on-board computer
LED, and that there is a clear path between them (See NOTE below).
NOTE NOTE
• FOR BEST RESULTS, THE CDM BODY SHOULD BE POSITIONED AT APPROXIMATELY 45° TO
GRADE (FIGURE 20-13). THE CDM MAY NOT PICK UP THE ON-BOARD COMPUTER DATA
STREAM IF THE CDM IS NOT POSITIONED PROPERLY WITH A CLEAR AND DIRECT PATH
FROM THE ON-BOARD COMPUTER TO THE CDM.
3. Wait approximately 30 seconds for a value to appear in the display window.
4. If a value does not appear in the display window after 30 seconds, try adjusting the aim of the CDM
slightly and repeating step 4 until a value appears. If there is still no reading, check for weak batteries in
the CDM.
Once a value has been obtained in the display window, the CDM may be removed from its receiving position
and the data reviewed. The CDM will hold the values for F1, F2, F3, and F4 until the CDM is turned off or it
receives another line of data from the same or another on-board computer. Use the following procedure to
review the data stored in the CDM:
1. The value currently displayed will be F1 (battery voltage).
2. To view F2, press and hold the button on the CDM. When "Func 2" appears in the display window,
release the button. The value for F2 will then be displayed.
3. To view F3, press and hold the button on the CDM until "Func 3" appears in the display window.
Release the button. The value for F3 will be displayed.
4. To view F4, press and hold the button on the CDM until "Func 4" appears in the display window.
Release the button. The value for F4 will be displayed.
NOTE NOTE
• THE VALUES OF ALL FOUR FUNCTIONS CAN BE RECALLED BY PRESSING AND RELEASING
THE CDM BUTTON.
