Engine Controls - Tests W/codes - 3.5l Chrysler New Yorker XIV

MODEL IDENTIFICATION

Model and engine combinations identified in MODEL IDENTIFICATION table are equipped with On-Board Diagnostics-I (OBD-I).

MODEL IDENTIFICATION

INTRODUCTION

If no faults were found while performing BASIC DIAGNOSTIC PROCEDURES, proceed with self-diagnostics. If no Diagnostic Trouble Codes (DTCs) or only pass codes are present after entering self-diagnostics, perform NTC-1A for engine being diagnosed. If after performing appropriate NTC-1A tests, problem is not identified and repaired, proceed to TESTS W/O CODES article for diagnosis by symptom (i.e., ROUGH IDLE, NO START, etc.).

SYSTEM DIAGNOSTICS

Note. Self-diagnostic tests are written specifically for Chrysler's Diagnostic Readout Box (DRB). A generic scan tool may not be capable of performing all necessary test functions. Malfunction Indicator Light (MIL), also known as CHECK ENGINE light can be used, but has limited diagnostic capability.

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 Light (MIL) 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 approximately 50 ignition on/off cycles on all models except LH body. On LH body, PCM cancels trouble code after approximately 50-100 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.

Hard Failures

Hard failures cause MIL 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.

Intermittent Failures

Intermittent failures may cause MIL 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.

SERVICE PRECAUTIONS

Before proceeding with diagnosis, the following precautions must be followed

1. Always check if any Technical Service Bulletins (TSBs) apply to vehicle.
2. 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»(/chrysler/new-yorker/xiv-1994-1996/remont/testing-diagnostics/#engine-controls-tests-wcodes-35l__fuel-pressure-release) .
3. 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»(/chrysler/new-yorker/xiv-1994-1996/remont/computer-relearn/#computer-relearn-procedures) article in GENERAL INFORMATION before disconnecting battery.
4. Vehicle must have a fully charged battery and functional charging system.
5. Probe PCM 60-pin connector from pin side. DO NOT backprobe PCM connector.
6. DO NOT cause short circuits when performing electrical tests. This will set additional trouble codes, making diagnosis of original problem more difficult.
7. DO NOT use a test light instead of a voltmeter.
8. 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.
9. DO NOT prolong testing of fuel injectors, or engine may hydrostatically (liquid) lock.
10. Always repair lowest trouble code number (MIL) or first trouble code message displayed (scan tool) first.
11. Always perform verification procedure test after repairs are made.
12. Always disconnect scan tool after use.
13. Always disconnect scan tool before charging battery.

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.

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 MIL or scan tool. See ENTERING ON-BOARD DIAGNOSTICS . If trouble codes are not present and/or scan tool is used, proceed to TEST TC-1A . Perform indicated VERIFICATION PROCEDURE test after repairs. See SELF-DIAGNOSTIC TESTS DIRECTORY table.

ENTERING ON-BOARD DIAGNOSTICS

Note. Although other scan testers are available, manufacturer recommends using DRB (Diagnostic Readout Box) to diagnose the system. Malfunction Indicator Light (MIL), also known as CHECK ENGINE light function can be used, but has limited diagnostic capability.

Malfunction Indicator Light (MIL) 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 MIL.
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 MIL begins to flash trouble codes, it cannot be stopped. Start over if count is lost. Code 55 indicates end of trouble code display.
5. Refer to «TROUBLE CODES»(/chrysler/new-yorker/xiv-1994-1996/remont/testing-diagnostics/#engine-controls-tests-wcodes-35l) to translate trouble code number to a scan tool trouble code message. Once trouble area is identified, refer to «TEST TC-1A»(/chrysler/new-yorker/xiv-1994-1996/remont/testing-diagnostics/#engine-controls-tests-wcodes-35l) . Use scan tool trouble codes to find appropriate test.
6. When scan tool trouble code message is obtained, refer to appropriate test number. To clear trouble codes, see «CLEARING TROUBLE CODES»(/chrysler/new-yorker/xiv-1994-1996/remont/testing-diagnostics/#engine-controls-tests-wcodes-35l__clearing-trouble-codes) .

Scan Tool Diagnostic Mode

1. Turn ignition off. Connect scan tool to Data Link Connector (DLC). See DATA LINK CONNECTOR (DLC) table for connector location. (Scheme 1) DATA LINK CONNECTOR (DLC) Application DLC Location Concorde, Intrepid, LHS, New Yorker & Vision Right Of Steering Column, Next To Center Console
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 scan tool, access and record trouble codes.
4. When scan tool trouble code message is obtained, refer to appropriate test number. To clear trouble codes, see CLEARING TROUBLE CODES.

Scheme 1

CLEARING TROUBLE CODES

1. If scan tool is not available, go to next step. If scan tool is available, follow prompts to erase trouble codes.
2. Trouble codes may be cleared by disconnecting negative battery cable for at least 15 seconds, allowing PCM to clear trouble codes.

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

1. Visually inspect related wiring harness connectors for broken, bent, pushed out or corroded terminals.
2. Visually inspect related wiring harnesses for chafed, pierced or partially broken wires.
3. Check all pertinent Technical Service Bulletins (TSBs).

FUEL PRESSURE RELEASE

Multipoint Fuel Injection (MFI)

1. Turn ignition off. Disconnect negative battery cable. Slowly open fuel tank cap to release pressure in tank. Remove fuel rail pressure test port cap. Place open end of Fuel Pressure Release Hose (C-4799-1) in approved gasoline container. NOTE: Fuel Pressure Gauge (C-4799-A) contains Hose (C-4799-1).
2. Connect other end of pressure release hose to test port. As fuel pressure release hose is tightened onto fuel rail pressure test port, fuel pressure will bleed-off into container.

Throttle Body Injection (TBI)

1. Slowly open fuel tank cap to release pressure in tank. Disconnect 2-pin injector connector at edge of throttle body. Connect a jumper wire between injector connector (injector side) Dark Green/Orange wire and battery positive terminal.
2. Connect another jumper wire to injector connector (injector side) White/Dark Blue wire (AA, AJ and AN bodies) or Light Blue wire (AS body). Momentarily ground jumper wire connected to White/Dark Blue wire (AA, AJ and AN bodies) or Light Blue wire (AS body) for no more than 5 seconds. Injector will energize open, relieving fuel pressure. Remove jumper wires. Fuel pressure is now released.
