NOTE: This information does not apply to carberated engines, as they
will not have a check engine light and no codes are retrievable. Diagnostic Trouble Codes (DTC)
may be accessed by installing a spare fuse into the fuse box diagnostic
terminal, located under the LH side of the instrument panel, then turning
the ignition On.
Reading trouble codes
The instrument panel Check Engine lamp displays the DTCs. In normal operation
the lamp will light when the ignition is turned On. However, two different
lamp functions can occur when the engine is started. The lamp may turn off
immediately, indicating there is no fault at that time, or stay lit, informing
the vehicle operator that there is a system failure. If the lamp stays lit
a DTC will be stored in the ECM memory. When a DTC is accessed from the
ECM memory the Check Engine lamp will flash in a series, indicating the
DTC number. When multiple system failures occur applicable DTCs will be
indicated three times each. DTCs will continue to flash as long as the ignition
is On, and the diagnostic switch terminals are grounded.
Clearing Codes
DTCs may be erased by disconnecting and isolating the battery ground cable
for more than 60 seconds, or after 50 key cycles if the malfunction has
not recurred.
On models with OBD II, the DTCs may be cleared with the scan tool, following
the tool manufacturer’s instructions.
