SYSTEM DIAGNOSTICS

Note. If MIL does not come on for 2-3 seconds and then go off, bulb may be defective, or problem may exist on circuit (CCD Bus) between Powertrain Control Module (PCM) and instrument cluster. If problem exists with CCD Bus, this problem may be displayed when using scan tool to retrieve DTCs.

DIAGNOSTIC PROCEDURE

If no faults were found while performing procedures in BASIC DIAGNOSTICS PROCEDURES article, proceed with self-diagnostics. Always perform a visual inspection before attempting to diagnose engine control system problems. See VISUAL INSPECTION. Retrieve DTCs using scan tool only. See RETRIEVING DTCS.

VISUAL INSPECTION

Most engine control system driveability problems result from faulty wiring, poor electrical connections, improper wire routing, or leaking air and vacuum hose connections. Inspect all engine control system components, hoses, connectors and wiring for damage before proceeding with system testing.

INACTIVE DTC CONDITION

This procedure applies if you have been sent here from self-diagnostic tests and have just attempted to simulate condition that initially set DTC. The following additional checks may assist in identifying a possible intermittent problem

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

VEHICLES WITH FUEL RAIL TEST PORT

Loosen fuel cap. Ensure ignition is off. Remove protective cap from fuel rail test port. Place one end of Fuel Pressure Release Hose (C-4799-1) into an approved fuel container. Attach remaining end of hose to fuel rail test port. Use care, as fuel system may be under pressure. Fuel pressure will be released from fuel system. Remove hose, reinstall protective cap, and fuel cap. Wait 5 seconds. Use care when disconnecting fuel lines, as some fuel pressure may still exist in fuel lines.

VEHICLES WITHOUT FUEL RAIL TEST PORT

  1. Remove fuel pump relay from Power Distribution Center (PDC). PDC is located next to battery. Refer to label under PDC cover for relay location. Start and run engine until it stalls. Attempt to start engine. Continue restarting engine until it will no longer run. Turn ignition off. CAUTION: DO NOT supply power to fuel injector for more than 4 seconds, or fuel injector may be damaged.
  2. Disconnect any fuel injector connector. Connect a jumper wire between either fuel injector terminal and positive battery terminal. Connect another jumper wire to other fuel injector terminal. Momentarily touch other end of jumper wire to negative battery terminal.
  3. Place a shop towel under fuel line quick-connector at fuel rail. Use care when disconnecting fuel lines, as some fuel pressure may still exist in fuel lines. Disconnect fuel line quick-connector. Reinstall fuel pump relay in PDC. NOTE: One or more DTCs may set when fuel pump relay is removed.
  4. Erase DTCs after fuel pressure release procedure. See CLEARING DTCS under SELF-DIAGNOSTIC SYSTEM.

SELF-DIAGNOSTIC TESTS

Note. Unless otherwise indicated, self-diagnostic tests apply to gasoline engines only. Not all DTCs listed in DTC MESSAGES & CODES table are used on all models.

Note. Self-diagnostic tests are written specifically for Chrysler's Diagnostic Readout Box-III (DRB-III) scan tool. If using a generic scan tool, ensure scan tool is OBD-II certified. A generic scan tool may not be capable of performing all necessary test functions.

Note. Powertrain Control Module (PCM) connectors "A", "B" and "C" may also be referred to as connectors C1, C2 and C3 respectively.

Note. Sensor ground circuits may be identified as sensor return circuits.
