Engine Controls - Trouble Shooting - No Codes - Coupe: Introduction

CAUTION: When battery is disconnected, vehicle computer and memory systems may lose memory data. Driveability problems may exist until computer systems have completed a relearn cycle. See COMPUTER RELEARN PROCEDURES article in GENERAL INFORMATION before disconnecting battery.

Before diagnosing symptoms or intermittent faults, perform basic diagnostic procedures in BASIC DIAGNOSTIC PROCEDURES - SEBRING COUPE & STRATUS COUPE article and applicable self-diagnostic tests in SELF-DIAGNOSTICS - SEBRING COUPE & STRATUS COUPE - 2.4L article or SELF-DIAGNOSTICS - SEBRING COUPE & STRATUS COUPE - 3.0L article. Use this article to diagnose driveability problems existing when a hard fault code is not present.

NOTE: Some driveability problems may have been corrected by manufacturer with a revised Engine Control Module (ECM) or Powertrain Control Module (PCM). Check with manufacturer for latest ECM/PCM application.

Symptom checks direct the technician to malfunctioning component(s) for further diagnosis. A symptom should lead to a specific component, system test or adjustment.

Use intermittent test procedures to locate driveability problems that do not occur when the vehicle is being tested. These problems may cause a noticeable driveability problem or cause the Malfunction Indicator Light (MIL) to illuminate on some vehicles. These test procedures should also be used if a soft (intermittent) trouble code is present, but no problem is found during self-diagnostic testing.

NOTE: For specific DTC testing procedures, see SELF-DIAGNOSTICS - SEBRING COUPE & STRATUS COUPE - 2.4L article or SELF-DIAGNOSTICS - SEBRING COUPE & STRATUS COUPE - 3.0L article. For specifications, see ON-VEHICLE ADJUSTMENTS - SEBRING COUPE & STRATUS COUPE and SERVICE & ADJUSTMENT SPECIFICATIONS - SEBRING COUPE & STRATUS COUPE articles. For system or component testing, see SYSTEM & COMPONENT TESTING - SEBRING COUPE & STRATUS COUPE article or SYSTEM & COMPONENT TESTING - SEBRING COUPE & STRATUS COUPE article.
