Dodge Spirit R/T 1992 - 1992 ENGINE PERFORMANCE Self-Diagnostics - 2.2L Turbo

Dodge Spirit R/T 1992 - INTRODUCTION

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 in the GENERAL INFORMATION before disconnecting battery.

If no faults were found while performing BASIC TESTING , proceed with self-diagnostics. If no fault codes or only pass codes are present after entering self-diagnostics, proceed to appropriate TESTS W/O CODES article in the ENGINE PERFORMANCE Section for diagnosis by symptom (i.e., ROUGH IDLE, NO START, etc.).

Dodge Spirit R/T 1992 - SELF-DIAGNOSTIC SYSTEM

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 in the GENERAL INFORMATION before disconnecting battery.

Dodge Spirit R/T 1992 - SYSTEM DIAGNOSTICS

The self-diagnostic capabilities of this system, if properly utilized, can simplify testing. The Single Board Engine Controller (SBEC) monitors several different engine control system circuits.

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

Once codes are known, see FAULT CODES table to determine the questionable circuit. Test circuits and repair or replace components as required. If problem is repaired or ceases to exist, the SBEC cancels fault code after 50 ignition on/off cycles. To clear codes, see CLEARING FAULT CODES.

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

Dodge Spirit R/T 1992 - Hard Failures

Hard failures cause 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, SBEC 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.

Dodge Spirit R/T 1992 - Intermittent Failures

Intermittent failures may cause CHECK ENGINE light to flicker or stay on until the intermittent fault goes away. However, the corresponding fault code will be retained in SBEC memory. If related fault does not reoccur within a certain time frame, related fault code will be erased from SBEC memory. Intermittent failures can be caused by a faulty sensor, bad connector or wiring related problems. See INTERMITTENTS in appropriate TESTS W/O CODES article in the ENGINE PERFORMANCE Section.

Dodge Spirit R/T 1992 - 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 the GENERAL INFORMATION Section before disconnecting battery.
• Vehicle must have a fully charged battery and functional charging system.
• Probe SBEC 60-pin connector from pin side. DO NOT backprobe SBEC connector.
• DO NOT cause short circuits when performing electrical tests. This will set additional fault 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 SBEC may result.
• DO NOT prolong testing of fuel injectors or engine may hydrostatically (liquid) lock.
• Always repair lowest fault code number (CHECK ENGINE light) or first fault displayed (DRB-II) first.
• Always perform verification procedure test after repairs are made.
• Always disconnect DRB-II after use.
• Always disconnect DRB-II before charging battery.

Dodge Spirit R/T 1992 - 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.

Dodge Spirit R/T 1992 - DIAGNOSTIC PROCEDURE

NOTE:

DO NOT skip any steps in self-diagnostic tests or incorrect diagnosis may result.

Always perform a visual inspection before attempting to diagnose engine control system problems. See VISUAL INSPECTION. Enter on-board diagnostics, and retrieve fault code(s). See ENTERING ON-BOARD DIAGNOSTICS. If fault codes are not present and/or DRB-II (Diagnostic Readout Box-II) is used, proceed to one of the following tests:

• Go to TEST NS-1A (NO-START TEST 1A) if a no-start condition exists or engine stalls after start-up. Perform indicated VERIFICATION PROCEDURE test after repairs. Ensure self- diagnostic tests apply to engine being tested.
• Go to TEST DR-1A (DRIVEABILITY TEST 1A) if engine runs but has performance problems. Perform indicated VERIFICATION PROCEDURE test after repairs. Ensure self-diagnostic tests apply to engine being tested.
• Go to TEST NF-1A (NO FAULT CODE TEST 1A) if a driveability problem exits and no fault codes are present. Perform indicated VERIFICATION PROCEDURE test after repairs. Ensure self-diagnostic tests apply to engine being tested.

Dodge Spirit R/T 1992 - ENTERING ON-BOARD DIAGNOSTICS

NOTE:

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

Dodge Spirit R/T 1992 - SYSTEM TEST Mode

This mode is not available in the engine diagnostics program.

Dodge Spirit R/T 1992 - READ FAULTS Mode

This mode allows user to read and erase fault codes. A fault counter will appear along with fault displayed. As an example, DRB-II will display 1 OF 2 FAULTS. SBEC will store up to 8 fault messages. Faults are numbered in reverse order of setting. The most recent fault to occur will be displayed first. Vehicles without air conditioning will always have A/C CLUTCH RELAY CKT (circuit) stored in memory. This fault will always be displayed first if vehicle is not equipped with A/C. If no fault messages are stored, DRB-II will display NO FAULTS DETECTED and start counter will show 0 STARTS SINCE ERS (Erased).

A start counter will appear below DRB-II fault counter display. Start counter counts the number of times vehicle is started since faults were last set or erased or battery was disconnected. This helps determine if fault is intermittent. Memory space limits start counter to first 3 faults. Start counter of zero equals a hard fault. Start counter of more than zero indicates an intermittent fault. Start counter will count up to 255 starts. If no fault messages are stored, DRB-II will display NO FAULTS DETECTED and start counter will show 0 STARTS SINCE ERS (Erased).

Dodge Spirit R/T 1992 - STATE DISPLAYS Mode

This mode provides access to FUEL/IGN STATE menu. FUEL/IGN STATE menu permits viewing groups of data regarding the SBEC, sensor and switch inputs, controlled outputs, and predetermined or user selectable groups of data.

Dodge Spirit R/T 1992 - VERIFICATION TESTS VERIFICATION PROCEDURE VER-1

NOTE:

For connector terminal identification, see CONNECTOR IDENTIFICATION. For appropriate wiring diagram, see WIRING DIAGRAMS at end of article.

Inspect vehicle to ensure all engine components are connected. Reassemble and reconnect components as necessary. Attempt to start engine. If engine does not start, return to TEST NS-1A.

If engine starts, Single Board Engine Controller (SBEC) was changed, and vehicle is equipped with factory theft alarm, start vehicle at least 20 times so alarm system may be activated when desired. No-start condition is corrected and repair is now complete.

If engine starts and SBEC has not been changed, connect DRB-II to engine diagnostic connector, and erase faults. No-start condition has been corrected and fault messages have been erased. Repair is now complete.

Dodge Spirit R/T 1992 - VERIFICATION PROCEDURE VER-2

NOTE:

For connector terminal identification, see CONNECTOR IDENTIFICATION. For appropriate wiring diagram, see WIRING DIAGRAMS at end of article.

If TEST VER-3 was performed previously, perform TEST VER-3 again. Inspect vehicle to ensure all engine components are connected. Reassemble and reconnect components as necessary. If another fault was read previously and was not corrected, return to TEST DR-1A and follow path specified by other fault. If Single Board Engine Controller (SBEC) was replaced, perform following:

1) If vehicle is equipped with a factory theft alarm, start vehicle at least 20 times so alarm system may be activated as desired. Connect DRB-II to engine diagnostic connector, and erase faults. Ensure no other fault remains by starting engine and allowing it to reach normal operating temperature.

2) Increase engine speed to 2000 RPM for at least 10 seconds. Allow engine to idle. On A/T models, apply brake and cycle transmission through all gear ranges. Place gear selector in Park position. On vehicles equipped with air conditioning, turn on air conditioning. Set blower to low speed.

3) On all models, turn engine off. Start engine. Allow engine to idle for at least 2 minutes. Turn engine off. Using DRB-II, read fault messages. If repaired fault resets, repair is not complete.

4) Check all pertinent TECHNICAL SERVICE BULLETINS (TSBs) and return to TEST DR-1A if necessary. If another fault exists, return to TEST DR-1A and follow path specified by other fault. If other faults do not exist, repair is now complete.
