Fuel Module Reservoir Assembly Overheating Recall

1. 1Fault

   • Leak
   • Overheating
   • Smoke or fire
   • Stalls or shuts off
   • Warning light
   • Check engine / Service Engine Soon
   • Some vehicles were built with fuel module reservoir assemblies whose fuel pump wires and/or connectors may overheat under certain operating conditions.
   • If the exposed ignition circuit wire shorts to ground, the fuel pump fuse blows, disabling the fuel pump and causing an engine stall or no-start; if the ignition circuit or ground wire shorts to the fuel level sender card wires, fuel level readings may be inaccurate.
   • If enough heat reaches the pass-through connector, a hole may form in it, which may turn on the Service Engine Soon light during the emission system diagnostics routine; fuel vapor, and in some cases liquid fuel, may leak from the tank through the hole.
   • If enough fuel leaked out and an ignition source were present, a vehicle fire could occur.
   ↓→

2. 2Finding the cause

   • Fuel Pump Connector: overheated

   Possible causes

   • Fretting corrosion caused by vibration inside the tank was identified as the cause of high resistance within the fuel pump connector.
   ↓→

3. 3Correction

   • Fuel Tank: replaced
   • Module Reservoir: replaced

   Repair

   1. Dealers remove the fuel tank, remove the fuel module reservoir assembly and install a new service kit, which includes a new pass-through connector and a wiring harness for the fuel pump and fuel sender card.
   2. Start by disconnecting the negative battery cable, then remove and discard the "ECM B" fuse.
   3. In the revised bulletin, the fuel and EVAP pipes are capped with J 41413-300, EVAP Cap/Plug Kit, to prevent fuel system contamination.
   4. Remove the 4 pin Metri Pack 150 electrical connector from the vehicle's body harness.
   5. Connect the new GT280 connector to the vehicle's body harness with the 4 butt splice connectors contained in the kit.

   • P0300
   • P0301
   • P0302
   • P0303
   • P0304
   • P0305

   • DTCs P0300 (engine misfire detected) and P0301 through P0308 (misfire detected on cylinders 1 through 8) are listed.
   ↓→

2. 2Finding the cause

   Possible causes

   • Possible causes: worn camshaft lobe and/or lifter roller, a sticking valve, valve leakage, a broken valve spring, or a collapsed AFM lifter.

   Steps to confirm (in the document’s order)

   1. A verified noise is not eliminated by canceling fuel injectors and occurs at camshaft speed (half of crankshaft speed).
   2. If applying pressure to the valve side of the rocker changes the noise, a lifter and/or cam lobe concern on that cylinder is most likely.
   3. Disconnect the coils and injectors on one bank, run the engine with that valve cover removed, back off the rocker arm a couple of turns and listen for a change in the noise.
   4. Measure cam lobe lift at the pushrod side of the rocker arm and compare with other rockers on the same bank; the misfiring or ticking cylinder should have clearly less lift.
   5. A good indicator of a sticking valve is misfires that keep counting on an aggressive deceleration with engine braking.

3. 3Correction

   Repair

   • If a worn camshaft lobe or lifter roller is found, replace the camshaft and all lifters, and the plastic lifter guide for the affected lifter.

   Caution

   • A damaged cam lobe is easy to overlook through the lifter bores, and unworn lifter rollers do not mean the cam lobes are okay; inspect both carefully.

   What the documents say to do

   Parking brake linings worn out prematurely, parking brake does not hold (PBR single-shoe drum-in-hat)

   Confirm

   • On complaint vehicles examined in the field, wear occurred earlier and to a greater extent on the driver's side parking brake unit and was largely localized at the tip of one of the linings.

   Repair

   1. A revised clip designed to exert less force on the shoe went into MY 2003 production and into the service part stream. Installing the newer clip and replacing worn linings has been shown to remedy the defect.
   2. The closing report lists a bulletin of Aug 2004 as 02-05-26-001B "Brakes - Parking Brake Shoe Retainer Clip Availability", announcing a new retainer clip service kit for DIH-equipped vehicles.

   Caution

   • The vehicles warn the operator with a chime if driven over 3 mph (= 4.83 km/h) with the parking brake engaged.

EVAP Leak Diagnostic Service Bulletin (DTCs P0442/P0455)

1. 1Fault

   • Leak
   • Warning light
   • P0442
   • P0455
   • The MIL is illuminated, and DTC P0442 (EVAP small leak detected) and/or P0455 (EVAP large leak detected) may be set in the ECM.
   ↓→

2. 2Finding the cause

   Possible causes

   • P0455 sets because of a large leak or a purge blockage: an unseated tube connection, a damaged tube, a canister vent valve stuck open, or a purge valve stuck closed.
   • P0442 sets because of a small leak, which can come from a purge valve stuck open or a canister vent valve stuck open.

   Steps to confirm (in the document’s order)

   1. Inspect every purge connection for proper installation, and look along the lines for damage or wear; if damage is seen, confirm it with the smoke test.
   2. Some leaks show only under pressure and some only under vacuum, so check both ways; cycling the purge and vent solenoids with GDS2 while inspecting may show a sticking valve.
   3. Critical connections to check include: purge tube to purge valve (at the intake manifold), purge tube to chassis EVAP line (rear of the engine, near the transmission), chassis EVAP line to canister, and fuel tank load line to canister.
   4. Also check the vent valve line at the vent valve, the fuel tank load line jumper connection near the fuel tank, and that the fuel tank cap is closed properly.
   5. If all connections are good, check the vent valve for a stuck-open position; if the vent valve works correctly, go on to the purge valve.

   ↓→

2. 2Finding the cause

   Possible causes

   • These methods find small leaks around the O2 sensor embossments and slight cracks in an intake plenum or gasket.

   Steps to confirm (in the document’s order)

   1. If normal SI diagnostics do not lead to a resolution and an intake vacuum leak or exhaust leak is suspected, use the GE-52250 Variable Pressure Leak Detector (preferred), the J-41416 ultrasonic leak tester, or possibly soapy water with low pressure air into the tailpipe to find the leak.
   2. For an intake leak, introduce the smoke into the brake booster hose or the oil dipstick tube; soapy water can be sprayed near the gasket, seams and all vacuum nipples.
   3. For an exhaust leak, put the hose with smoke or air into the tailpipe sealed with shop towels, then spray soapy water around seals, seams and bosses.

   ↓→

2. 2Finding the cause

   Possible causes

   • Monitoring devices and other electronic accessories such as aftermarket cruise control or police speed checking devices (RADAR or LIDAR) may cause one or more of the listed concerns.
   • Many of the problems could come from an open connection on the HSCAN bus; a device that connects to only one CAN + causes bus errors and erratic ECU behavior.

   Steps to confirm (in the document’s order)

   • If normal SI diagnostics find no other root cause, check for a device plugged into the ALDL or Data Link Connector (DLC) for tracking and/or maintenance interval scheduling.
   ↓→

3. 3Correction

   Repair

   1. If SI diagnostics do not find the source and the device is available, try to duplicate the condition, then remove the device to see whether the condition is eliminated.
   2. If removing the DLC interface device resolves the concern, tell the customer the result and that they should work with the device's supplier for further resolution.

   Caution

   • The device and the rest of its harness can be hidden out of sight, and the technician may not notice that the diagnostic connector is not in the factory location.

   • Condition 2: a Service Suspension System message on the DIC, possibly with low rear ride height under a heavy payload, and DTC C0711 set in the ESC module.
   • Condition 3: a loose hose hangs down at the left rear; upon inspection the hose may be found damaged or disconnected from the air inlet filter of the auto leveling suspension air compressor.
   ↓→

2. 2Finding the cause

   Possible causes

   • Condition 1 can be caused by the wiring to the automatic level control (ALC) pressure sensor being shorted to ground.
   • Condition 2 may be caused by an internal fault in the ALC pressure sensor, which can occur when moisture gets into the sensor.

   Steps to confirm (in the document’s order)

   1. The air compressor assembly may have to be removed to see whether the wiring is pinched between the compressor assembly and the frame.
   2. If system pressure at start up is below 10 psi (69 kpa), the system runs the compressor to add air to the shocks as a replenishment cycle.
   ↓→

3. 3Correction

   Repair

   1. For condition 1, repair any damaged or shorted circuits and reposition the wiring so it is not damaged again when the compressor assembly is installed.
   2. The sensor is no longer serviced separately; to replace it, install a complete air filter, dryer and sensor assembly.
   3. For condition 3, replace the auto leveling compressor air inlet filter and hose assembly (PN 22197160).
