Test TC-1A - Checking System For DTCS

WARNING: This page is about a different car, the 1995 Plymouth Voyager, 1995 Plymouth Grand Voyager, 1995 Dodge Grand Caravan, and 1995 Dodge Caravan. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: For circuit and connector terminal identification, see CONNECTOR IDENTIFICATION . For wiring diagrams, see WIRING DIAGRAMS section.

NOTE: Battery must be fully charged before proceeding.

Ensure battery is fully charged before proceeding. Attempt to start engine; crank engine for at least 10 seconds if necessary. Connect scan tool to Data Link Connector (DLC). Record scan tool Diagnostic Trouble Codes (DTCs).
If scan tool has a blank screen or displays an error message, this indicates a scan tool failure. To diagnose and correct these conditions, see CHRYSLER CORP. BODY CONTROL COMPUTER article in the ENGINE PERFORMANCE section.
If scan tool displays NO RESPONSE, go to TEST NS-6A. If DTCs are displayed, see SCAN TOOL DTCS table. If no DTCs are displayed and a driveability problem is present, go to TEST NTC-1A. If no DTCs are displayed and a no-start problem is present, go to TEST NS-1A.

⁽¹⁾	If engine temperature does not reach 176°F (80°C) after 20 minutes of driving, check cooling system. This code may also set in error during very cold, slow speed driving.

⁽²⁾	Replace Powertrain Control Module (PCM), and perform TEST VER-1.

⁽³⁾	Refer to CHRYSLER CORP. - GENERATORS & REGULATORS article in the ELECTRICAL section.
