Test FC-1A - Checking System For Faults

NOTE: For connector terminal identification, see CONNECTOR IDENTIFICATION . For wiring diagram, see WIRING DIAGRAMS article in this section.

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 Data Link Connector (DLC). Record DRB-II fault messages.
If DRB-II displays ERROR message, go to TEST NS-6A. If DRB-II has a blank screen or displays RAM TEST FAILURE, CARTRIDGE ERROR, KEY PAD TEST FAILURE, LOW BATTERY or HIGH BATTERY, DRB-II failure is indicated. To diagnose and correct problem, see G - BODY TESTS W/ CODES article. If DRB-II displays fault messages, see DRB-II FAULT MESSAGES table and perform appropriate tests. If DRB-II does not display fault messages, go to TEST NS-1A for no-start tests or NF-1A for no fault code tests.

⁽¹⁾	ZJ models have one oxygen sensor. Only LEFT O2S DRB messages apply. If messages for RIGHT O2S appear, DRB may be faulty.

⁽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 TEST VER-1 .

⁽⁴⁾	See ALTERNATOR & REGULATOR article in the ELECTRICAL Section.

⁽⁵⁾	Refer to CRUISE CONTROL SYSTEM article in the ACCESSORIES & SAFETY EQUIPMENT section.
