CHECKING FOR TROUBLE CODES 4.4
CHECK ENGINE LAMP
To diagnose system problems, start by observing the behav-
ior of the check engine lamp.
NOTES
● All references to “Key ON” or “Ignition Switch ON” require
that the ignition key be in the ON position and the engine
stop switch be set to RUN.
●
If the check engine lamp is not illuminated at Key ON or if
it fails to turn OFF after the initial four second period,
then a problem exists in the lamp circuit. See 4.9 CHECK
ENGINE LAMP NOT ILLUMINATED AT KEY ON or 4.10
CHECK ENGINE LAMP ON CONTINUOUSLY for more
information.
1. When the ignition switch is turned ON after being OFF
for 2 seconds or more, the check engine lamp will illumi-
nate for approximately four seconds and then turn off.
2. See Figure 4-5. After lamp turns off after being illumi-
nated for the first four second period, one of three situa-
tions may occur.
a. The lamp remains off. This indicates there are no
current fault conditions or stored functional trouble
codes currently detected by the ECM.
b. The lamp stays off for only four seconds and then
comes back on for an eight second period. This indi-
cates a functional error code is stored, but no cur-
rent trouble code exists.
c. If the lamp remains on beyond the eight second
period, then a current trouble code exists.
3. See CODE TYPES for a complete description of trouble
code formats.
