BULLETIN NUMBER: WB23-X-001 IMPORTANT SERVICE INFORMATION FOR: ✓ DEALER PRINCIPAL ✓ SALES MANAGER ✓ SERVICE MANAGER ✓ SERVICE ADVISOR ✓ WARRANTY PERSONNEL ISSUE DATE: OCTOBER 2023 GROUP: MISCELLANEOUS VEHICLE STORAGE BEYOND 30 DAYS SPPM SECTION 2.15 / 2.16 POLICY REMINDER AFFECTED VEHICLES • 2012 and Newer Isuzu Commercial Vehicles INFORMATION This bulletin provides information with regards to the Isuzu Commercial Vehicle (CV) Service Policies and Procedures Manual (SPPM). What is “Vehicle Storage”?: Isuzu considers a vehicle to be in “storage” up to the point it is delivered to the end customer for use OR until it is “retail delivered” in the Isuzu Communication System (ICS). This storage period starts the day the vehicle is wholesaled to the dealer. During this period the “Isuzu Dealer” to which the vehicle was wholesaled to is solely responsible for the care and maintenance of the vehicle until it is “retail delivered” in ICS regardless of the vehicle’s location (i.e., dealer front lot, dealer remote storage lot, modification center, dealer designated body builder or other dealer designated drop shipment location). The Isuzu CV SPPM (sections 2.15 and 2.16) provides detailed procedures related to vehicle storage up to and beyond 30 days. Performing these required procedures at the specified intervals will properly maintain vehicles until they are retailed. Failure to follow the procedures outlined may result in repairs and additional costs that could have been avoided. We are providing dealers with this brief overview of the recommended procedures as a reminder to maintain older inventory. Failures resulting from improper, or lack of, storage procedures are not covered under the vehicle factory warranty. STORAGE OVERVIEW Less Than 30 Days • Regularly inspect the paint for airborne pollutants (fallout) and apply a thick coat of wax to prevent discoloration. • Protect the upholstery to prevent fading and damage. • Apply silicon protectant to keep any rubber parts, particularly weather-stripping, pliable and protected. • Lubricate any mechanical linkage. • Start the engine every two weeks and run until completely warmed up. Avoid storage under trees or in grass or weeds where bird droppings, insect nests or rodents may cause damage. More Than 30 Days - Add the Following: • • • • • • • Check and inflate tires to manufacturer’s maximum specifications. Shift the transmission through all the gears while the engine is running. Move the vehicle at least 30 feet and re-park to avoid forming flat spots on the tires. Check the fuel caps. Air out the cab. Remove the wiper arms. Store them in a safe place (inside the cab) out of direct sunlight. Disconnect the negative battery cable; ensure battery voltage is 12.5 V or higher. Note: When the negative battery cable is reconnected, the MID date and time should be properly set. • Check the battery voltage every 30 days and ensure battery voltage is 12.5 V or higher. Charge as necessary to maintain the correct voltage. Note: If battery voltage falls below 12.5 V, problems may occur in the field before the battery has a chance to become fully charged once the vehicle is being driven regularly. More Than 6 Months - Add the Following: • Drain and refill Diesel Exhaust Fluid (DEF). More Than 1 Year - Add the Following: • Replace engine oil, coolant, brake fluid, transmission oil, differential gear oil and all other fluids. • Any Vehicle maintenance that is required after 12 months according to the owner manual maintenance schedule. Note: For exact procedures, refer to sections 2.15 and 2.16 of the Service Policies and Procedures Manual (SPPM).
