SPECIAL TEST MENU<br />
• X or XX - These characters identify the location of the O2 sensor in<br />
relation to a cylinder bank. An O2 sensor for cylinder bank 1 is<br />
identified by the designation “1” or "B1"; a sensor for cylinder bank 2<br />
is identified as “2” or "B2."<br />
”Bank One” indicates the side of the engine where cylinder<br />
number one is located (V-type engines). Bank Two is opposite<br />
of Bank One.<br />
• Y or YY - These characters identity the location of the O2 sensor in<br />
relation to the exhaust system catalyst. An O2 sensor located upstream<br />
of the catalyst is identified by the designation”1” or "S1", a sensor located<br />
downstream of the Catalytic Converter is identified as “2” or "S2."<br />
For example, O2S12 or O2SB1S2 is the designation for the<br />
downstream O2 sensor for cylinder bank 1.<br />
The Scan Tool does not perform O2 sensor tests, but retrieves<br />
results from the most recently performed O2 sensor tests from<br />
the on-board computer's memory. You may retrieve O2 sensor<br />
test results for only one test of one sensor at any given time.<br />
1. From the "Special Test Menu", use the<br />
UP and DOWN buttons, as<br />
necessary, to highlight O2 Sensor Test,<br />
then press the ENTER button.<br />
2. A "One moment please..." message<br />
displays while the request is sent to the<br />
vehicle's on-board computer.<br />
• The "Select Sensor" screen<br />
displays. The screen shows all O2<br />
sensors applicable to the vehicle<br />
under test.<br />
If O2 sensor tests are not<br />
supported by the vehicle under<br />
test, an advisory message shows<br />
on the Scan Tool's display. Press<br />
the LD/M button to return to<br />
the “System Test Menu.”<br />
3. Use the UP and DOWN buttons,<br />
as necessary, to highlight the O2 sensor<br />
for which you wish to view test results,<br />
then press the ENTER button.<br />
4. When test results have been retrieved,<br />
data for the selected sensor test will<br />
show on the Scan Tool's display.<br />
5. When you have finished viewing the<br />
retrieved test data, press the LD/M<br />
button to return to the "Select sensor"<br />
screen.<br />
