CIRCUIT DESCRIPTION
Use a properly functioning scan tool with the diagnostic tables in this section. DO NOT use the Clear Info function unless instructed by a diagnostic procedure.

IMPORTANT: This vehicle, equipped with a Powertrain Control Module (PCM), utilizes an Electrically Erasable Programmable Read Only Memory (EEPROM). Program the new PCM when the diagnostics call for replacement of the PCM. Refer to PCM Replacement/Programming.

TEST DESCRIPTION
The numbers below refer to the step numbers on the diagnostic table.
3. An engine that lust cranks and does not attempt to start indicates that the PCM is not powered-up. Refer to PCM Schematic for PCM harness terminal numbers.
5. A ground must be available at both terminals for the scan tool to operate.
8. A no start condition occurs when the fuses for the battery and ignition feed circuits are open. The MIL is inoperative when the battery and ignition feed circuit fuses open. Inspect the circuits for being grounded when either of these fuses open.
14. If the test lamp does not illuminate for a circuit, inspect the fuse for being open. If the fuse is open, inspect the circuit for a short to ground.
15. Inspect for an open fuse 11 in the Instrument Panel Fuse Block. If the fuse is open, repair the grounded circuit.
