Chrysler LeBaron LE 1994 - 1994 ENGINE PERFORMANCE Self-Diagnostics - 3.0L


Chrysler LeBaron LE 1994 - INTRODUCTION SYSTEM DIAGNOSTICS

The self-diagnostic capabilities of this system, if properly utilized, can simplify testing. The Powertrain Control Module (PCM) monitors several different engine control system circuits.

If a problem is sensed with a monitored circuit, PCM memory stores a trouble code, the malfunction indicator (CHECK ENGINE) light glows and PCM enters limp-in mode. In limp-in mode, PCM compensates for component failure by substituting information from other sources. This allows vehicle operation until repairs can be made.

Test circuits and repair or replace components as required. If problem is repaired or ceases to exist, the PCM cancels trouble code after 50 ignition on/off cycles.

A specific trouble code results from a particular system failure. A trouble code does not condemn a specific component; component is not necessarily the reason for failure. Trouble codes only call out a probable malfunction area.


Chrysler LeBaron LE 1994 - Hard Failures


Hard failures cause malfunction indicator (CHECK ENGINE) light to glow and remain on until the malfunction is repaired. If light comes on and remains on (light may flash) during vehicle operation, cause of malfunction must be determined using self-diagnostic tests. If a sensor fails, PCM will use a substitute value in its calculations, allowing engine to operate in limp-in mode. In this condition, vehicle will run, but driveability may be poor.


Chrysler LeBaron LE 1994 - Intermittent Failures


Intermittent failures may cause malfunction indicator (CHECK ENGINE) light to flicker or stay on until the intermittent trouble code goes away. However, the corresponding trouble code will be retained in PCM memory. If related trouble code does not reoccur within a certain time frame, related trouble code will be erased from PCM memory. Intermittent failures can be caused by a faulty sensor, bad connector or wiring related problems.

Chrysler LeBaron LE 1994 - SELF-DIAGNOSTIC SYSTEM SERVICE PRECAUTIONS


Before proceeding with diagnosis, the following precautions must be followed:

  • ALWAYS relieve fuel pressure before disconnecting any fuel injection-related component. DO NOT allow fuel to contact engine or electrical components. See FUEL PRESSURE RELEASE .
  • 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 section before disconnecting battery.
  • Vehicle must have a fully charged battery and functional charging system.
  • Probe PCM 60-pin connector from pin side. DO NOT backprobe PCM connector.
  • DO NOT cause short circuits when performing electrical tests. This will set additional trouble codes, making diagnosis of original problem more difficult.
  • DO NOT use a test light instead of a voltmeter.
  • When checking for spark, ensure coil wire is NO more than 1/4" from ground. If coil wire is more than 1/4" from ground, damage to vehicle electronics and/or PCM may result.
  • DO NOT prolong testing of fuel injectors or engine may hydrostatically (liquid) lock.
  • Always repair lowest trouble code number (CHECK ENGINE light) or first trouble code message displayed (DRB) first.
  • Always perform verification procedure test after repairs are made.
  • Always disconnect DRB after use.
  • Always disconnect DRB before charging battery.

Chrysler LeBaron LE 1994 - VISUAL INSPECTION


Most driveability problems in the engine control system result from faulty wiring, poor electrical connections or leaking air and vacuum hose connections. To avoid unnecessary component testing, perform a visual inspection before beginning self-diagnostic tests.


Chrysler LeBaron LE 1994 - DIAGNOSTIC PROCEDURE


NOTE: DO NOT skip any steps in self-diagnostic tests or incorrect diagnosis may result. Ensure self-diagnostic tests apply to engine being tested.

If no trouble codes were found while performing BASIC DIAGNOSTIC PROCEDURES, proceed with self-diagnostics. Always perform a visual inspection before attempting to diagnose engine control system problems. See VISUAL INSPECTION . Enter on-board diagnostics, and retrieve trouble code(s) using CHECK ENGINE light or DRB. See ENTERING ON-BOARD DIAGNOSTICS. If trouble codes are not present and/or DRB (Diagnostic Readout Box) is used, proceed to TEST TC-1A . Perform indicated VERIFICATION PROCEDURE test after repairs. See SELF-DIAGNOSTIC TESTS DIRECTORY table.


Chrysler LeBaron LE 1994 - ENTERING ON-BOARD DIAGNOSTICS


NOTE: Although other scan testers are available, manufacturer recommends using DRB (Diagnostic Readout Box) to diagnose the system. Malfunction indicator (CHECK ENGINE) light function can be used, but has limited diagnostic capability.


Chrysler LeBaron LE 1994 - CHECK ENGINE Light Diagnostic Mode


  1. Start engine (if possible). Move transmission shift lever through all positions, ending in Park. Turn A/C switch on and then off (if equipped).
  2. Turn engine off. Without starting engine again, turn ignition on, off, on, off and on within 5 seconds. Record 2-digit trouble codes as displayed by flashing malfunction indicator (CHECK ENGINE) light.
  3. For example, trouble code 23 is displayed as flash, flash, 4-second pause, flash, flash, flash. After a slightly longer pause, other codes stored are displayed in numerical order.
  4. When CHECK ENGINE light begins to flash trouble codes, it cannot be stopped. Start over if count is lost. Code 55 indicates end of trouble code display.
  5. - TROUBLE CODES to translate trouble code number to a DRB trouble code message. Once trouble area is identified, refer to TEST TC-1A . Use DRB trouble codes to find appropriate test.
  6. As an example, a 3.0L engine starts and runs but has a driveability problem. Malfunction indicator (CHECK ENGINE) light indicates a Code 14. - TROUBLE CODES to translate trouble code number to a DRB trouble code message.
  7. When DRB trouble code message is obtained, refer to appropriate test number in this article. To clear trouble codes, see CLEARING TROUBLE CODES .

Chrysler LeBaron LE 1994 - DRB Diagnostic Mode


  1. Turn ignition off. Connect DRB to engine diagnostic connector. Engine diagnostic connector is located in engine compartment, near PCM.
  2. Start engine (if possible). With foot on brake, move transmission shift lever through all positions, ending in Park. Turn A/C switch on and then off (if equipped).
  3. Turn engine off. Without starting engine again, turn ignition on. Using DRB, access and record trouble codes.
  4. When DRB trouble code message is obtained, refer to appropriate test number in this article. To clear trouble codes, see CLEARING TROUBLE CODES.

Chrysler LeBaron LE 1994 - CLEARING TROUBLE CODES


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 section before disconnecting battery.

  1. If DRB is not available, go to next step. If DRB is available, select FUEL/IGNITION. Select ADJUSTMENTS. Follow DRB prompts to erase trouble codes.
  2. Fault codes may be cleared by disconnecting negative battery cable for at least 15 seconds, allowing PCM to clear trouble codes.

Chrysler LeBaron LE 1994 - INACTIVE TROUBLE CODE CONDITION


This procedure applies if you have been sent here from diagnostic charts and have just attempted to simulate the condition that initially set the trouble code. The following additional checks may assist in identifying a possible intermittent problem:

  • Visually inspect related wiring harness connectors for broken, bent, pushed out or corroded terminals.
  • Visually inspect related wiring harnesses for chafed, pierced or partially broken wires.
  • Check all pertinent MITCHELL(R) TECH SERVICE BULLETINS (TSBs).

Chrysler LeBaron LE 1994 - USING DRB


NOTE: Although other scan testers are available, manufacturer recommends using DRB (Diagnostic Readout Box) to diagnose the system.

Ensure DRB is connected to engine diagnostic connector located in engine compartment. Ensure correct cartridge is installed in DRB for vehicle and system being diagnosed. Menu selections will vary depending on vehicle and system being diagnosed. Follow DRB screen prompts to actuate, adjust, monitor, reset, test and diagnose system as necessary.

DRB is grounded through engine diagnostic connector, only one volt-ohmmeter test lead is required when using volt-ohmmeter option. DRB volt-ohmmeter should only be used when self-diagnostic tests require the use of this option.

If DRB has a blank screen or displays RAM TEST FAILURE, CARTRIDGE ERROR, KEY PAD TEST FAILURE or LOW OR HIGH BATTERY, this indicates a DRB failure. To diagnose/correct conditions, see VEHICLE COMMUNICATIONS TESTS in TESTS W/CODES - BODY CONTROL COMPUTER article (for AJ Body) and TESTS W/CODES - TRAVELER MODULE article (for AA and AP Bodies) in the ENGINE PERFORMANCE section.


Chrysler LeBaron LE 1994 - FUEL PRESSURE RELEASE


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 section before disconnecting battery.

CAUTION: DO NOT energize only one injector to relieve fuel pressure. Energize 3 different injectors. Energizing only one injector to relieve all fuel pressure may hydrostatically lock engine. DO NOT ground injector for more than 5 seconds.
