Test FC-1A - Checking For Faults

NOTE: For connector terminal identification, see CONNECTOR IDENTIFICATION . For appropriate wiring diagram, see WIRING DIAGRAMS at end of article.

Battery must be fully charged before proceeding. Attempt to start engine. If engine will not start, crank engine for at least 10 seconds. Connect DRB-II to engine diagnostic connector. Record DRB-II fault messages.
If DRB-II has a blank screen or displays RAM TEST FAILURE, CARTRIDGE ERROR, KEY PAD TEST FAILURE, or LOW OR HIGH BATTERY, DRB-II failure is indicated. To diagnose and correct, see appropriate TESTS W/CODES - 3.3L/3.8L article in this section.
If DRB-II displays NO RESPONSE, go to TEST NS-6A. If fault messages are displayed, see DTC & DRB-II FAULT MESSAGES table. If no fault messages are displayed and a driveability problem is present, go to TEST NF-1A. If no fault messages are displayed and a no-start problem is present, go to TEST NS-1A.

⁽¹⁾	Refer to appropriate ALTERNATORS & REGULATORS article in the ELECTRICAL Section.

⁽²⁾	Check cooling system if engine temperature does not reach 176°F (80°C) after driving 20 minutes. This code may set in error during very cold slow speed driving.

⁽³⁾	Replace PCM and perform VERIFICATION PROCEDURE VER-1.
