Self-Diagnostics - 2.0l Subaru Impreza WRX GD/GG рестайлинг

INTRODUCTION

To properly diagnose and repair this vehicle, follow DIAGNOSTIC PROCEDURE under SELF-DIAGNOSTIC SYSTEM. If no Diagnostic Trouble Codes (DTC) are present and a no-start condition exists, proceed to BASIC DIAGNOSTIC PROCEDURES article. If no DTCs are present and a driveability condition exists, proceed to TROUBLE SHOOTING - NO CODES article for diagnosis by symptom (i.e., ROUGH IDLE, ENGINE STALLS, etc.).

ON-BOARD DIAGNOSTICS

Engine Control Module (ECM) monitors engine operation and contains a self-diagnostic system which stores Diagnostic Trouble Codes (DTCs) and complies with On-Board Diagnostics Generation II (OBD-II) standards.

Self-diagnostic system is used to provide vehicle with an on-board diagnostic system which is capable of continuously monitoring efficiency of emission control system, and improving diagnosis and repair when system failures occur.

Federal Test Procedure (FTP) sets maximum allowable emission standards. Malfunction Indicator Light (MIL) must illuminate if a system or component either fails or deteriorates to a point where the vehicle emissions could increase to more than 1 1/2 times FTP standards.

If malfunction does not recur in 3 ignition cycles, MIL goes off, but DTCs remain recorded in ECM memory. DTCs may only be retrieved using an On-Board Diagnostic-II (OBD-II) scan tool that complies with SAE standard J-1978 or Subaru Select Monitor connected to Data Link Connector (DLC). Scan tool also provides freeze-frame data and can be used to clear codes.

Hard Failures

Hard failures cause MIL to illuminate and remain on until problem is repaired. If MIL comes on and remains on (light may flash) during vehicle operation, cause of malfunction must be determined using Diagnostic Trouble Code (DTC) charts. If a sensor fails, the Engine Control Unit (ECU) will use a substitute value in its calculations to continue engine operation. In this condition, commonly known as limp-in mode, vehicle runs but driveability will not be optimum.

Intermittent Failures

Intermittent failures may cause MIL to flicker or illuminate then go out after intermittent fault goes away. However, a corresponding DTC will be retained in ECM memory. If related fault does not reoccur within a certain time frame, related DTC will be erased from ECM memory. Intermittent failures may be caused by sensor, connector or wiring related problems. See INTERMITTENTS in TROUBLE SHOOTING - NO CODES article.

BASIC DIAGNOSTIC PROCEDURE

Note. Check for applicable Technical Service Bulletins (TSBs) before proceeding. DO NOT perform the following procedure if driveability conditions are not present. DO NOT turn ignition off during the following procedure or clear DTCs unless instructed to do so.

Note. Subaru Select Monitor (SSM) or OBD-II generic scan tool must be used to perform basic diagnostic procedure. Follow scan tool manufacturer's instructions for proper operation. Communication with vehicle's on-board computer is through the OBD-II Data Link Connector (DLC). (Scheme 57) For scan tool functions see SCAN TOOL USAGE.

1. Verify customer complaint and conditions under which fault appears. Attempt to start engine. If engine starts, go to next step. If engine does not start, see «NO-START DIAGNOSIS»(/subaru/impreza-wrx/gdgg-2002-2005/remont/testing-diagnostics/#engine-controls-basic-diagnostic-procedures__no-start-diagnosis) in BASIC DIAGNOSTIC PROCEDURES article.
2. Does the (CHECK ENGINE) Malfunction Indicator Light (MIL) illuminate, indicating a system fault? If yes, go to next step. If no, see «SYMPTOMS»(/subaru/impreza-wrx/gdgg-2002-2005/remont/testing-diagnostics/#engine-controls-trouble-shooting-no-codes) in TROUBLE SHOOTING - NO CODES article.
3. Turn ignition OFF. Connect the Subaru Select Monitor (SSM) or OBD-II generic scan tool to data link connector (DLC). Turn ignition and scan tool ON. Retrieve Diagnostic Trouble Codes (DTCs). Record any DTCs indicated on the scan tool. Repair the trouble cause. See «DIAGNOSTIC TROUBLE CODE DEFINITIONS»(/subaru/impreza-wrx/gdgg-2002-2005/remont/testing-diagnostics/#self-diagnostics-20l__diagnostic-trouble-code-definitions) . After repairs are complete, go to next step. If no DTCs are indicted on the scan tool and (CHECK ENGINE) MIL is illuminated, see «MALFUNCTION INDICATOR LIGHT (MIL) DOES NOT GO OFF»(/subaru/impreza-wrx/gdgg-2002-2005/remont/testing-diagnostics/#self-diagnostics-20l__malfunction-indicator-light-mil-does-not) under SYSTEM CHECKS.
4. Perform the CLEAR MEMORY MODE. See «CLEARING DIAGNOSTIC TROUBLE CODES»(/subaru/impreza-wrx/gdgg-2002-2005/remont/testing-diagnostics/#self-diagnostics-20l) . Perform the Inspection Mode. See «INSPECTION MODE»(/subaru/impreza-wrx/gdgg-2002-2005/remont/testing-diagnostics/#self-diagnostics-20l__inspection-mode) under DRIVE CYCLES. If the scan tool indicates any DTCs, see «DIAGNOSTIC TROUBLE CODE DEFINITIONS»(/subaru/impreza-wrx/gdgg-2002-2005/remont/testing-diagnostics/#self-diagnostics-20l__diagnostic-trouble-code-definitions) . If no DTCs are indicated on the scan tool, system is okay.

Scheme 57

DIAGNOSTIC PROCEDURE

Diagnosis of computerized engine control system should be performed in the following order

1. Ensure all engine systems not related to computer system are operating properly. DO NOT proceed with testing unless all other problems have been repaired. Basic diagnostic procedure must be performed before using specific DTC testing procedure. See «BASIC DIAGNOSTIC PROCEDURE»(/subaru/impreza-wrx/gdgg-2002-2005/remont/testing-diagnostics/#self-diagnostics-20l__basic-diagnostic-procedure) .
2. If DTCs were displayed, determine whether codes are hard or intermittent. Hard codes will cause MIL to illuminate continuously while engine is running. See «HARD FAILURES»(/subaru/impreza-wrx/gdgg-2002-2005/remont/testing-diagnostics/#self-diagnostics-20l__hard-failures) and «INTERMITTENT FAILURES»(/subaru/impreza-wrx/gdgg-2002-2005/remont/testing-diagnostics/#self-diagnostics-20l__intermittent-failures) . For diagnosing hard codes, see «DIAGNOSTIC TROUBLE CODE DEFINITIONS»(/subaru/impreza-wrx/gdgg-2002-2005/remont/testing-diagnostics/#self-diagnostics-20l__diagnostic-trouble-code-definitions) . For diagnosing intermittent codes, see «INTERMITTENTS»(/subaru/impreza-wrx/gdgg-2002-2005/remont/testing-diagnostics/#engine-controls-trouble-shooting-no-codes) in TROUBLE SHOOTING - NO CODES article
3. If no DTCs are present and a driveability problem exists, refer to «SYMPTOMS»(/subaru/impreza-wrx/gdgg-2002-2005/remont/testing-diagnostics/#engine-controls-trouble-shooting-no-codes) in TROUBLE SHOOTING - NO CODES article. Doing so will help identify proper system or component to check in SYSTEM & COMPONENT TESTING article.

MALFUNCTION INDICATOR LIGHT (MIL) ACTIVATION

Note. The MIL, also referred to as Check Engine light, is a warning light on the instrument cluster.

Operation

When the ignition switch is turned on, the (CHECK ENGINE) Malfunction Indicator Light (MIL) illuminates. If the MIL does not illuminate, see MALFUNCTION INDICATOR LIGHT (MIL) DOES NOT COME ON . After starting the engine, the MIL goes out. If the MIL does not go out, either the engine or emission control system is malfunctioning. If the diagnosis system senses a misfire which could damage the catalyzer, the MIL will blink at a cycle of 1Hz. When the ignition switch is turned ON, with engine OFF, or to START position with the Test Mode Connector connected, the MIL will blink at a cycle of 3 Hz.

MALFUNCTION INDICATOR LIGHT (MIL) DOES NOT COME ON

Diagnosis

The CHECK ENGINE MIL circuit is open or shorted.

Trouble Symptom

When the ignition switch is turned ON, with engine off, MIL does not illuminate.

1. Check output signal form Engine Control Module (ECM). Turn ignition ON and measure the voltage between ECM connector B137, terminal No. 15 and chassis ground. If the measured value is less than 1.0 volt, go to step 4. If the measured value is more than 1.0 volt, go to next step. (Scheme 78)
2. Check for poor contact at ECM. If the MIL illuminates when shaking or pulling on the ECM connector, repair poor connection as necessary. If the MIL does not illuminate while shaking or pulling on the ECM connector, go to next step.
3. Check the ECM connector to ensure connector is properly connected. If the ECM connector is properly connected, replace the ECM. See «ENGINE CONTROL MODULE»(/subaru/impreza-wrx/gdgg-2002-2005/remont/removal-installation/#engine-controls-removal-installation-impreza-outback-sport) under COMPUTERIZED ENGINE CONTROLS in REMOVAL & INSTALLATION article. If the ECM connector is not properly connected, repair connector as necessary.
4. Check harness between combination meter and ECM connector. Turn ignition OFF. Remove the combination meter and disconnect the connector. Disconnect the ECM connector. Measure the resistance between ECM connector B137, terminal No. 15 and combination meter connector i12, terminal No. 6. If the measured value is less than 1.0 ohm, go to next step. If the measured value is greater than 1.0 ohm, repair open circuit in harness between ECM and combination meter connector or poor contact in coupling connector. (Scheme 78)
5. Check for poor contact in combination meter connector. If there is a poor contact in the combination meter connector, repair as necessary. If combination meter connector is okay, go to next step.
6. Check harness between combination meter and ignition switch connector. Turn ignition switch ON. Measure the voltage between combination meter connector i10, terminal No. 7 and chassis ground. If the measured valve is more than 10 volts, replace combination meter. If measured value is less than 10 volts, replace blown fuse No. 13, repair open or short in harness between fuse No. 13 and ignition switch battery terminal, or repair poor contact in ignition switch. (Scheme 78)

Scheme 78

MALFUNCTION INDICATOR LIGHT (MIL) DOES NOT GO OFF

The CHECK ENGINE MIL circuit is shorted.

Although MIL comes on when the engine is running, a DTC is not shown on the Subaru Select Monitor or OBD-II General Scan Tool display.

Check the harness between combination meter and ECM connector. Turn the ignition OFF. Disconnect the connector form the ECM. Turn the ignition ON. If the MIL illuminates, repair the short in the harness between the combination meter and the ECM connector. (Scheme 78) If the MIL does not illuminate, replace the ECM. See ENGINE CONTROL MODULE under COMPUTERIZED ENGINE CONTROLS in REMOVAL & INSTALLATION article.

MALFUNCTION INDICATOR LIGHT (MIL) DOES NOT BLINK AT A CYCLE OF 3HZ

The CHECK ENGINE MIL circuit is open or shorted. Test Mode Connector is open.

When in inspection mode, MIL does not blink at a cycle of 3 Hz.

1. Check status of CHECK ENGINE MIL. Turn ignition OFF. Disconnect the Test Mode Connector. Turn ignition ON, engine off. If MIL alienates, go to next step. If MIL does not illuminate, see «MALFUNCTION INDICATOR LIGHT (MIL) DOES NOT COME ON»(/subaru/impreza-wrx/gdgg-2002-2005/remont/testing-diagnostics/#self-diagnostics-20l__malfunction-indicator-light-mil-does-not).
2. Check harness between combination meter and ECM connector. (Scheme 79) Turn ignition OFF. Disconnect ECM connector. Turn ignition ON. If MIL illuminates, repair short to ground in harness between combination meter and ECM connector. If MIL does not illuminate, go to next step.
3. Check harness between Test Mode Connector and chassis ground. Turn ignition OFF. Disconnect ECM connector. Measure the resistance between test harness connector B76, terminal No. 1 and chassis ground. (Scheme 79) If the measured value is less than 1 ohm, go to next step. If measured resistance is more than 1 ohm, repair open in harness between Test Mode Connector and chassis ground.
4. Check for poor contact in the ECM connector. If there is a poor contact in the ECM connector, repair as necessary. If ECM connector is okay, go to next step.
5. Check harness between ECM and Test Mode Connector. Connect the Test Mode Connector. Measure the resistance between ECM connector B134, terminal No. 14 and chassis ground. (Scheme 79) If the measured value is less than 1 ohm, go to next step. If the measured value is more than 1 ohm, repair open between ECM and Test Mode Connector.
6. Check for poor contact in ECM connector. If there is a poor contact in the ECM connector, repair as necessary. If ECM connector is okay, replace ECM. See «ENGINE CONTROL MODULE»(/subaru/impreza-wrx/gdgg-2002-2005/remont/removal-installation/#engine-controls-removal-installation-impreza-outback-sport) under COMPUTERIZED ENGINE CONTROLS in REMOVAL & INSTALLATION article.

Scheme 79

MALFUNCTION INDICATOR LIGHT (MIL) REMAINS BLINKING AT A CYCLE OF 3HZ

Test Mode Connector circuit is shorted.

MIL blinks at a cycle of 3 Hz when the ignition is on.

1. Check Test Mode Connector. Disconnect the Test Mode Connector, Turn ignition ON. If the MIL blinks ON and OFF, go to next step. If MIL does not blink ON and OFF, system is okay.
2. Check harness between ECM connector and engine ground terminal. Turn ignition OFF. Disconnect the ECM connector. Measure the resistance between ECM connector B134, terminal No. 14 and chassis ground. If the measured value is less than 5 ohms, repair short in harness between ECM and Test Mode Connector. If measured value is greater than 5 ohms, replace ECM. See «ENGINE CONTROL MODULE»(/subaru/impreza-wrx/gdgg-2002-2005/remont/removal-installation/#engine-controls-removal-installation-impreza-outback-sport) under COMPUTERIZED ENGINE CONTROLS article.
