lf the self-diagnostic E indicator light does not blink, perform an inspection according to the table below.
SymptomInspectionRef. page
E indicator light does not come on for two seconds after ignition switch
is first turn on (ll).14-262
E indicator light is on constantly (not blinking) whenever the ignition
switch is on (ll).14-264
NOTE:
. lf a customer described the symptom for code P1706 (6), it will be necessary to recreate the symptom by test driving,
then recheck the DTC.
. Sometime the E indicator light and the Malfunction Indicator lamp (MlL) may come on simultaneously. lf so, repair the
pGM-Fl system according to the DTc, then reset the memory by removing the BACK uP fuse in the under-hood
fuse/relay box for more than 10 seconds. Drive the vehicle for several minutes at a speed over 30 mph (50 km/h)' then
recheck the DTC.
