CHECK FOR INTERMITTENT
PROBLEMS
HINT:
Inspect the vehicle's ECM using check mode. Intermittent
problems are easier to detect with the intelligent tester when
the ECM is in check mode. In check mode, the ECM uses 1
trip detection logic, which is more sensitive to malfunctions
than normal mode (default), which uses 2 trip detection logic.
1. Clear the DTCs (see page ES-39).
2. Switch the ECM from normal mode to check mode using
the intelligent tester (see page ES-42).
3. Perform a simulation test.
4. Check and wiggle the harness(es), connector(s) and
terminal(s).

BASIC INSPECTION
When a malfunction is not confirmed by the DTC check,
troubleshooting should be carried out in all circuits
considered to be possible causes of the problem. In many
cases, by carrying out the basic engine check shown in the
following flowchart, the location of the problem can be found
quickly and efficiently. Therefore, using this check is essential
when performing engine troubleshooting.
NOTICE:
Conduct this check with the engine stopped and ignition
switch OFF.
