90-823225--1 10965E-52 - ELECTRONIC FUEL INJECTION (MULTI-PORT AND THROTTLE BODY)
CLEARING CODES USING DIAGNOSTIC CODE
TOOL (NON-SCAN)
1. Install diagnostic code tool.
2. Turn key ON.
3. Select service mode on code tool.
4. To clear codes, move the throttle, while in neutral,
from 0% to 100% then back to 0%.
5. Exit “Service Mode” on code tool.
6. Start engine and let run for fifteen seconds.
7. Turn key OFF for 5 seconds.
8. Select “Service Mode” on code tool.
9. Turn key ON and read codes. If codes are still
present, check note following and repeat from
Step 1.
10. Refer to appropriate Troubleshooting and/or
Diagnostic Charts.
NOTE: When clearing codes without the use of a
scan tool, the battery must be fully charged and
cranking speed must be at least 300 RPM. The ability
to clear codes is directly dependent on the battery be-
ing fully charged and able to start the engine with ad-
equate cranking RPM.
A poorly charged battery or engine cranking problem
may result in an ECM “reset” and may not allow
stored trouble codes to be cleared from EEPROM
memory. If this condition exists, BE SURE the battery
is fully charged. If a low battery condition does exists
the audio warning buzzer will come on for 2 seconds
after engine start-up.
