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: Tests under DIAGNOSTIC TESTS are arranged with Diagnostic Trouble Code (DTC) tests followed by No Trouble Code (NTC) tests, No Start (NS) tests and concluding with Verification (VER) tests.

NOTE: For connector terminal ID, see CONNECTOR IDENTIFICATION .

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 replacing the Powertrain Control Module (PCM) the PCM must be properly programmed. See POWERTRAIN CONTROL MODULE PROGRAMMING under POWERTRAIN CONTROL MODULE.
