Typical Scan Data Values - Isuzu 1999 RODEO Workshop Manual

6E1–72
RODEO X22SE 2.2L ENGINE DRIVEABILITY AND EMISSION

TYPICAL SCAN DATA VALUES

Use the Typical Scan Data Values Table only after the
On–Board Diagnostic
completed, no DTC(s) were noted, and you have
determined that the on–board diagnostics are functioning
properly. Tech 2 values from a properly–running engine
may be used for comparison with the engine you are
diagnosing. The typical scan data values represent
values that would be seen on a normally–running engine.
NOTE: A Tech 2 that displays faulty data should not be
used, and the problem should be reported to the Tech 2
manufacturer. Use of a faulty Tech 2 can result in
misdiagnosis and unnecessary replacement of parts.
