FUNCTIONAL CHECK
1. Turn ignition "ON."
2. Enter diagnostics (refer to Diagnostic System Check for procedure).
A. Allow DTC 12 to flash four times to verify no other DTC(s) present. This indicates the PROM is installed properly.
B. If Diagnostic Trouble Code (DTC) 51 occurs or if the MIL (Service Engine Soon) is "ON" constantly with no DTC(s), the PROM is not fully
seated, installed backwards, has bent pins, or is defective.
^
If not fully seated, press firmly on PROM carrier.
^
If it is necessary to remove the PROM, follow instructions for removal and installation.
^
If installed backwards, REPLACE THE PROM.

If pins bend, remove PROM, straighten pins, and reinstall. If bent pins break or crack during straightening, discard PROM and replace it.
CAUTION: Any time the PROM is installed backward and the ignition switch turned "ON," the PROM is destroyed.
