Self-Diagnostic Tests: Notes

CAUTION: When battery is disconnected, vehicle computer and energy 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.

NOTE: For connector terminal ID, see CONNECTOR IDENTIFICATION .

NOTE: Some wiring circuits may contain a Positive Temperature Coefficient (PTC). The PTC is a specified amperage solid-state circuit breaker located in junction box behind driver's side of instrument panel, to the left of steering column. To reset PTC, all current must be removed from PTC for approximately 20 seconds.

NOTE: Before diagnosing an engine performance problem, refer to SYSTEM DIAGNOSTICS for diagnostic system functions, abilities and system diagnostic procedures.

NOTE: Before diagnosing an engine performance problem, refer to SERVICE PRECAUTIONS under SELF-DIAGNOSTIC SYSTEM before proceeding.

CAUTION: Ensure ignition is off before disconnecting connector at any component.

NOTE: Self-diagnostic tests are written specifically for Chrysler's Diagnostic Readout Box (DRB-III) scan tool, which will be referred to as DRB during testing procedures. If using a generic scan tool, ensure scan tool is OBD certified. A generic scan tool may not be capable of performing all necessary test functions.

NOTE: If Powertrain Control Module (PCM) is replaced, the PCM must be properly programmed. See POWERTRAIN CONTROL MODULE PROGRAMMING under POWERTRAIN CONTROL MODULE.
