The following background information is related
to this procedure:
Injector codes are seven digit alphanumeric codes
that are supplied with each injector. The code is
printed on each injector. The code is used by the
ECM to balance the performance of the injectors.
Refer to Troubleshooting, "Injector Code - Calibrate"
for further information.

Diagnostic Trouble Codes for " " Injector Data Incorrect" "
Description Notes
The Electronic Control Module (ECM) detects one of the fol-
lowing conditions.
An injector code has not been programmed for one or more of
the injectors.
OR
The injector code for one or more of the injectors is invalid.
The engine may have rough running at low idle.
The ECM will calibrate the injector energizing times while the
engine is at low idle based on the readings from the oxygen
sensor.
If the calculated energizing times exceed the limits set by the
injector code, one of these diagnostic codes will become active
for the applicable cylinder.
