ISSUE Some 2003-2005 Expedition/Navigator, 2004-2005 F-150 vehicles equipped with a 9.75? or 8.8? limited slip rear axle, and 2002-2005 Explorer 4dr, Mountaineer, Crown Victoria, Grand Marquis, Town Car, and Mustang vehicles equipped with 8.8? limited slip rear axle, may exhibit a chatter, shudder, a binding sensation, or a vibration during low speed turns. On 4×4 vehicles, the sensation may appear to be originating from the front axle or the steering gear. ACTION First verify the condition. On 4×4 trucks ensure that the vehicle is in 2WD, to isolate the rear axle. On all vehicles, turn the wheel fully right (or fully left) and then accelerate the vehicle. If the condition is verified to be in the rear axle, replace the limited slip clutch pack. SERVICE PROCEDURE

Fitting a Mitsubishi ECU The following steps outline the installation procedure: 1. Remove the factory ECU from the vehicle: Ensure the key is in the OFF position. The factory ECU is located on the left A pillar about 30cm above the floor. Unplug the wiring harness from the factory ECU. Remove the 6mm bolts (10mm socket) that retain the ECU and remove the ECU from the vehicle. DO NOT touch the exposed pins in the factory ECU connector. 2. Remove the factory ECUs circuit board from its enclosure: Ensure you are following the given anti-static guidelines and ARE WEARING A CONDUCTIVE WRIST STRAP connected to a conductive working surface. Using four small flat bladed screwdrivers, carefully pry apart the four plastic lugs retaining the ECUs header plate into the case. Some force may be required to remove the circuit board from the case as it may be partially glued to the inside. Remove the circuit board by removing the retaining screws. Hold it only by the plastic header and place it aside. 3. Connect the ECU USB tuning cable and the expansion loom if required. 4. Fit the Vi-PEC Plug-In ECU, there are several options depending on the vehicle: · EVO IV to VIII – If fitting to a short case, CAREFULLY snap the PCB extension off. It may be necessary to use a sharp knife to first score the break off points. Place the factory ECU in the packaging your Vi-PEC ECU came in for its protection. Carefully fit the supplied aluminium end plate to the enclosure. Make sure the end plate is fitted to allow any cables to exit on the left side of the header. · EVO IX – Place the factory ECU in the packaging your Vi-PEC ECU came in for its protection. Carefully fit the supplied aluminium end plate to the enclosure. Make sure the end plate is fitted to allow any cables to exit on the left side of the header. · All Others proceed to step 5 5. Install the Vi-PEC ECU circuit board into the enclosure, then fit the enclosure into the vehicle. 6. Connect the ECU to the factory wiring loom. 7. Do NOT attempt to start the vehicle. Proceed to read through the remaining sections of this manual first.

Subject: Models: Low Engine Coolant Level Indicator Always On (Diagnose Low Coolant Level System Operation/Check Sensor for Oil Contamination) 2000-2002 Buick Century, Regal 2000-2001 Chevrolet Lumina 2000-2002 Chevrolet Impala, Monte Carlo 2000-2002 Pontiac Grand Prix 2000-2002 Oldsmobile Intrigue Condition Some customers may comment that the low engine coolant level indicator is always illuminated. Cause The cause of this condition may be due to engine oil contaminating the coolant. Possible sources of oil contamination are internal engine leaks, improper service procedures, or the addition of some types of anti-leak additives to the cooling system. Once in the coolant, the oil leaves deposits on the level sensor creating an insulating film. This film results in a false activation of the coolant level indicator. Correction Diagnose low coolant level system operation and check the sensor for oil contamination using the procedure listed below. Important: No coolant supplements should be used in GM cooling systems, other than what is approved and recommended by GM. The use of “aftermarket” over-the-counter sealing and cooling supplements may affect the operation of the low coolant level sensor. Discoloration of the coolant recovery bottle is normal and does not necessarily indicate that coolant contamination is present. Flush cooling system only when instructed by this bulletin. 1. Verify that the coolant is at proper level in the radiator and the coolant recovery bottle. If the coolant is low, add proper amount of 50/50 water and DEX-COOL® mixture. If the low coolant light operates properly, diagnose the cooling system for loss of coolant as outlined in SI. DO NOT proceed further with this bulletin. 2. Remove the low coolant level sensor. Refer to Coolant Level Module Replacement in the Engine Cooling sub-section. 3. With the key on, the engine off and the coolant level sensor disconnected from the vehicle wiring harness, observe the low coolant light: • Light is on — Chassis wiring or instrument cluster concern. Follow the appropriate diagnostic information in SI. • Light is out — Proceed to Step 4.

DESCRIPTION: The Electronic Stability Control (ESC) of some 2006 Sonata vehicles equipped with 3.3 Liter engines may be programmed to be too sensitive, causing inadvertent brake application on banked curves. To correct this condition, the ESC ECU may be reprogrammed using the Hi-Scan Pro as described in this bulletin. VEHICLES AFFECTED: ^ Model: 2006 SONATA 3.3L vehicles with ESC ^ Affected vehicle production date range: ^ Produced from May 5, 2005 through June 10, 2005 ESC ECU SPECIFICATIONS: CAUTIONS BEFORE REPROGRAMMING: 1. Perform reprogramming with the ignition key in the “ON” position. 2. Be careful not to disconnect any cables connected to the vehicle or Hi-Scan Pro during reprogramming. WARNING : ^ When reprogramming the SONATA ESC ECU, the manual reprogramming mode [error mode] is not available. ^ If ESC ECU reprogramming is interrupted during the “ESC ECU software data download” process as a result of cable disconnection, power interruption or battery discharge, the ESC ECU must be replaced. 3. Do not start the engine during reprogramming. 4. Do not turn the ignition key OFF during reprogramming. 5. When the reprogramming is completed, wait for about 20 seconds and then start the engine to confirm proper operation of the vehicle. ESC ECU REPROGRAMMING: NOTE :Verify that the vehicle was manufactured within the affected production date range and the campaign is open per the DCS interactive screen. 1. Attach the Data Link Connector (DLC) cable to the Hi-Scan Pro main body and securely tighten the two bolts. 2. Remove the system software card from the Hi-Scan Pro and insert the reprogramming software card with the new ECU program into the Hi-Scan top slot.
