| 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. |
Note. Diagnostic tests are written specifically for Chrysler's Diagnostic Readout Box (DRBIII®) scan tool. A generic scan tool may not be capable of performing all necessary test functions.
Note. Throughout this article, models with California emissions may be referred to as Calif. or Calif. models. Vehicles from other states may be equipped with California emissions. Models with Federal emissions may be referred to as Federal or Federal models. Check underhood label for application.
New for 2003 for models equipped with the 4.7L is a combined Powertrain Control Module (PCM) and Transmission Control Module (TCM) in a single control module. This new module is the Next Generation Controller (NGC) and will be referred to as the PCM. New Diagnostics procedures and New DTCs are some of the changes you will see which reflect the new combined module technology. The PCM will have 4 color coded connectors C1 through C4, (C1-Black, C2-Gray, C3-White, C4-Green), each PCM connector will have 38 pins each. Two new tools are introduced to help in diagnosing and repairing the new PCM terminals and harness connectors. The Miller Terminal Removal Pick (3638) is introduced, you must use the Miller (3638) tool to release the connector terminals or harness and connector damage will occur. Also, the Miller Pinout Box (8815) is introduced, you must use the Miller (8815) tool to probe the PCM terminals or terminal damage will occur. There is also a new Verification Test and module replacement procedure for the new PCM.
New for 2003 models equipped with the 5.7L engine is the Next Generation Controller 2 (NGC2). The NGC2 controller removes RFE transmission control system and installs Electronic Throttle Control (ECT) module systems. ECT utilizes a new electronically controlled throttle body with two new TP sensors and accelerator pedal position sensors to control throttle opening. The NGC2 will be referred to as the PCM. The transmission control module is a separate controller (EATX). New Diagnostics procedures and New DTCs are some of the changes you will see which reflect the new combined module technology. The PCM will have 4 color coded connectors C1 through C4, (C1-Black, C2-Gray, C3-White, C4-Green), each PCM connector will have 38 pins each. Two new tools are introduced to help in diagnosing and repairing the new PCM terminals and harness connectors. The Miller Terminal Removal Pick (3638) is introduced, you must use the Miller (3638) tool to release the connector terminals or harness and connector damage will occur. Also, the Miller Pinout Box (8815) is introduced, you must use the Miller (8815) tool to probe the PCM terminals or terminal damage will occur. There is also a new Verification Test and module replacement procedure for the new PCM.
ON-BOARD DIAGNOSTICS
Note. Before performing any testing procedures, check for any related Technical Service Bulletins (TSB).
Note. Malfunction Indicator Light (MIL) may also be referred to as CHECK ENGINE light or SERVICE ENGINE SOON light.
MIL is located on instrument cluster, just below the tachometer and is displayed as an engine icon. When ignition is first turned on, MIL should come on and remain on for 2 seconds to verify bulb and circuit operation, and then go off. If MIL does not come on and remain on for 2 seconds and then go off when ignition is first turned on, check instrument cluster for diagnosis of MIL. See appropriate ANALOG INSTRUMENT PANELS article in ACCESSORIES & EQUIPMENT.
The Powertrain Control Module (PCM) monitors several different engine control system circuits. If malfunction occurs which affects vehicle emissions, a Diagnostic Trouble Code (DTC) will be set in PCM and PCM enters limp-in mode. In limp-in mode, PCM substitutes values for failed component and provides continuous engine operation. When DTC is set in PCM, the PCM will turn on MIL and MIL will remain on steady. In some instances, the MIL is turned on when the failure exists and DTC was set. These instances are referred to as one trip DTC. In many instances, the emission system must fail more then once before the PCM will turn on the MIL. These are referred to as a 2-trip DTC. For additional information for trip definition, see TRIP DEFINITION . If problem exists which does not affect vehicle emissions, a DTC will be set in PCM but MIL will not be turned on. OBD-II related DTCs are entered in PCM according to individual priority. The DTC priority determines when MIL is turned on and DTC self-erasure. For additional information for DTC priority and DTC self-erasure, see DIAGNOSTIC TROUBLE CODE PRIORITY & SELF-ERASURE . Non-emission related DTCs have no priority in which they are entered in the PCM.
PCM may not store a DTC for a monitored circuit even though a malfunction has occurred. This may happen because one of the criteria for DTC has not been met. For example, assume criteria for DTC requires PCM to monitor a specified sensor output circuit only when engine operates between 750 RPM and 2000 RPM. If the sensor output circuit becomes shorted to ground when engine is operating at 2400 RPM, DTC will not be set, as short to ground occurred at 2400 RPM which exceeds the limit when PCM monitors the circuit.
If PCM detects active engine misfire severe enough to cause catalytic converter damage, MIL will flash to warn the driver of possible damage and DTC will be set.
The PCM will turn off MIL when malfunction is not detected during 3 consecutive trips on all applications except an engine misfire monitor or fuel system monitor. For additional information on engine misfire monitor and fuel system monitor, see MONITORED CIRCUITS . The PCM will turn off MIL when malfunction is not detected during 3 engine misfire or fuel system monitor tests. The PCM performs engine misfire or fuel system monitor tests when engine is operating within 375 RPM and within 10 percent of the load of operating condition at which first malfunction was detected.
DTCs may be retrieved for system diagnosis. See RETRIEVING DIAGNOSTIC TROUBLE CODES . System malfunctions are identified as either hard failures or intermittent failures. For additional information on hard failures or intermittent failures, see HARD FAILURES and INTERMITTENT FAILURES .
Diagnostic Trouble Code Priority & Self-Erasure
With OBD-II, different OBD-II related Diagnostic Trouble Codes (DTC) have different priorities according to regulations. The DTC priority determines when Malfunction Indicator Light (MIL) will be turned on and DTC is erased or cleared from Powertrain Control Module (PCM). DTCs having a high priority will overwrite the lower priority DTCs. DTC priorities and description are as listed
- Priority "O" - This is a non-emission related DTC.
- Priority "1" - One-trip failure of a 2-trip DTC for non-fuel system and non-misfire conditions.
- Priority "2" - One-trip failure of a 2-trip DTC for fuel system rich or fuel system lean condition, or misfire condition.
- Priority "3" - Second trip failure for non-fuel system or non-misfire condition, or a one-trip failure.
- Priority "4" - Second trip failure for fuel system rich or fuel system lean and misfire condition, or a one-trip catalyst damaging misfire.
One-trip failures on a 2-trip DTC have low priority and 2-trip failures have higher priority. One and 2-trip failures for fuel system monitor and misfire monitor take precedence over non-fuel system and non-misfire failures. Non-emission related DTCs have no priority in which they are entered in the PCM.
After 3 good trips, PCM will turn off the MIL. Once MIL is turned off, trip counter is switched to a warm-up counter. PCM must not detect the recent malfunction during 40 warm-up cycles. A warm-up cycle is defined as the engine is started, an increase of 40°F in engine coolant temperature exists after engine is started and engine coolant temperature reaches at least 160°F (71°C). After 40 warm-up cycles with no malfunction, PCM will clear DTC from PCM. DTCs may be cleared from PCM using scan tool, but this will clear OBD-II monitor data such as counter information, warm-up cycles, trips and freeze frame data.
DIAGNOSTIC PROCEDURE
The procedures contained in this article include specifications, instructions and graphics needed to diagnose PCM powertrain system. The diagnostics are based on the failure condition or symptom being present at the time of diagnosis. Use the following recommendations
- First make sure the DRBIII® is communicating with the appropriate modules; i.e., if the DRBIII® displays a No Response condition, you must diagnose the condition first before proceeding. See appropriate BASIC DIAGNOSTIC PROCEDURES article (no response with a no-start condition) or appropriate BODY CONTROL MODULES article in ACCESSORIES & EQUIPMENT (all other no response conditions).
- Using DRBIII® scan tool read Diagnostic Trouble Codes (DTC). See «RETRIEVING DIAGNOSTIC TROUBLE CODES»(ref-157234-S21102842702003080700000) .
- If no DTCs are present, identify the customer complaint and diagnose by symptom. See appropriate TROUBLE SHOOTING - NO CODES article.
- If any DTCs are present, perform the appropriate diagnostic test. See «DIAGNOSTIC TROUBLE CODE DEFINITIONS»(ref-157234-S18137324412003080700000) .
RETRIEVING DIAGNOSTIC TROUBLE CODES
Note. Ensure battery is fully charged before retrieving Diagnostic Trouble Codes (DTC).
- Turn ignition off. Connect scan tool to Data Link Connector (DLC). DLC is located below driver's side of instrument panel. (Scheme 291) Turn ignition on. Using scan tool manufacturer's instructions, read and record DTC messages (DRB scan tool) or DTCs (generic scan tool) and freeze frame data.
- If scan tool displays a NO RESPONSE message, perform appropriate system test. See appropriate BODY CONTROL MODULES article in ACCESSORIES & EQUIPMENT. Repair as necessary. If scan tool does not power up, check for loose cable connections or bad cable. If cable connections or cable is defective, repair or replace components as necessary, then recheck for DTCs. If cable connections and cable are okay, go to next step.
- Measure voltage between ground and terminal No. 16 (Pink wire) at DLC. Voltage should be at least 11 volts. If voltage is as specified, go to next step. If voltage is not as specified, check fuse No. 51 (20-amp) in Integrated Power Module (IPM). If fuse is okay, check Pink wire between fuse No. 12 and DLC. See COMPUTER DATA LINES in appropriate SYSTEM WIRING DIAGRAMS article in ELECTRICAL.
- Measure resistance between ground and terminals No. 4 (Black/Dark Green) and No. 5 (Orange/Black wire) at DLC. If both resistance readings are less than 5 ohms, ground circuits are okay and it may be necessary to try another scan tool or cable. If any resistance reading is 5 ohms or more, repair open in Black/Dark Green wire or Orange/Black wire. See COMPUTER DATA LINES in appropriate SYSTEM WIRING DIAGRAMS article in ELECTRICAL.
- If scan tool displays an error message, (i.e., USER-REQUESTED COLD BOOT or USER-REQUESTED WARM BOOT), follow scan tool manufacturer's instructions. If scan tool displays a bus failure error message, this indicates a scan tool failure or a Bus circuit failure. To diagnose and repair Bus circuit failure, see appropriate BODY CONTROL MODULES article in ACCESSORIES & EQUIPMENT.
- If any DTCs are displayed, perform appropriate diagnostic test. See «DIAGNOSTIC TROUBLE CODE DEFINITIONS»(ref-157234-S18137324412003080700000). After repair is complete, clear DTCs from PCM memory and perform appropriate verification test. Verification tests are located at the end of the diagnostic tests. If no DTCs are displayed, go to one of the following: For starting or driveability problems, go to appropriate TROUBLE SHOOTING - NO CODES article for diagnosis by symptom. For speed control problems and servicing information, refer to appropriate CRUISE CONTROL SYSTEMS article in ACCESSORIES & EQUIPMENT. For charging system problems, refer to appropriate GENERATORS & REGULATORS article in STARTING & CHARGING SYSTEMS. For transmission electronic controls system problems, refer to appropriate DIAGNOSIS article in AUTOMATIC TRANSMISSIONS.
CLEARING DIAGNOSTIC TROUBLE CODES
Note. Clearing Diagnostic Trouble Codes (DTC) with a scan tool will also erase all OBD-II monitor data. This includes all counter information for warm-up cycles, trips and freeze frame data.
Connect scan tool to Data Link Connector (DLC). DLC is located below driver's side of instrument panel. (Scheme 291) Turn ignition on. Using screen prompts on scan tool, clear DTCs from Powertrain Control Module (PCM). DTCs may be cleared from PCM if PCM does not detect the recent malfunction during 40 warm-up cycles. For additional information, see DIAGNOSTIC TROUBLE CODE PRIORITY & SELF-ERASURE.

DIAGNOSTIC TESTS
| 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. |
Note. Before diagnosing an engine performance problem, refer to SERVICE PRECAUTIONS under SELF-DIAGNOSTIC SYSTEM before proceeding.
Note. Before diagnosing an engine performance problem, refer to ON-BOARD DIAGNOSTICS under SELF-DIAGNOSTIC SYSTEM for diagnostic system functions, abilities and system diagnostic procedures.
Note. Self-diagnostic tests are written specifically for Chrysler's Diagnostic Readout Box (DRBIII®) scan tool. A generic scan tool may not be capable of performing all necessary test functions.
Note. Throughout this article, models with California emissions may be referred to as Calif. or Calif. models. Vehicles from other states may be equipped with California emissions. Models with Federal emissions may be referred to as Federal or Federal models. Check underhood label for application.
Note. Before performing any testing procedures, check for any related Technical Service Bulletins (TSB).
