The Exchange Program must be used when any Alpine radio or other component covered by this bulletin is repaired under warranty and may also be used for radio and component repairs not covered under warranty. Contact Alpine directly for pricing and payment methods applicable to radio and component repairs not covered under warranty.
• 10235685Isuzu Commercial Truck of America (ICTA) has been receiving warranty part returns that have aftermarket catalytic converters welded in place instead of the OEM catalytic converter. This is because vehicle owners who have had the OEM or Fleet Value catalytic converters stolen from their vehicles often replace the stolen catalytic converters aftermarket with non-Isuzu parts. When those replacement parts fail and cause the check engine light to illuminate, vehicle owners may seek to have the non-Isuzu replacement catalytic converter repaired or replaced under warranty. In fact, however, neither the new vehicle warranty nor the one-year replacement part warranty covers the failed non-Isuzu part.
• 10233458What is IDA? IDA is a diagnostic program that provides: 1) DTC Analysis: IDA analyzed DTCs (currently 35) and then provides quick and easy-to-understand repair solutions 2) DPF Early Regeneration Warning: IDA also reviews the three latest DPF regeneration odometer readings in the Health Report of the applicable VIN on IDA. IDA then analyzes the distances between the three regenerations. If the average of these distances is less than 55 km for a 4HK1 (5.2L) engine, or less than 70 km for a 4JJ1 (3.0L) engine, an alert will be shown on the IDA page in the form of a red regeneration icon. This is an early warning indication that a problem may be forming in the DPF regeneration cycle. However, if the enabling criteria shown above are not met, a regeneration icon will not appear on the IDA for that particular VIN. Detailed instructions on how to use IDA are included in this bulletin.
• 10233457In the past 6.0L gasoline engines came as a new long block assembly. These engines are now provided as remanufactured long block assemblies. The remanufactured configuration does not include some of the same components as the previous new long block configuration did.
• 10232498The information below is provided to help technicians better understand common vehicle operations that may be incorrectly perceived by customers as a problem.

Also included is the clearing procedure for customers who have had transmitters lost or stolen. This procedure may be used to clear all transmitters from the Keyless Entry Control Unit.
• 10227136The vehicle's Malfunction Indicator Lamp (MIL) may illuminate with DTC P22FB and/or P22FE set in the DEF Control Unit (DCU). If one or more of the preceding DTCs are present, first follow the diagnostic for the DTC(s) in question. If no mechanical fault can be found during normal diagnosis, follow the service procedure in this bulletin to correct the concern.
• 10225521We have received reports of the front turn signal lenses cracking on Isuzu vehicles. These lenses are cracking from the effects of being washed with alkaline detergents. Alkaline detergents are typically used in industrial settings and are reactive with the paint, metals, and other materials used to make up the exterior components of Isuzu vehicles. Isuzu recommends that only neutral detergents be used when washing Isuzu vehicles. However, if alkaline detergents are used to wash an Isuzu vehicle, it is crucial that all traces of the detergent are rinsed away with water or wiped off as necessary. Allowing alkaline detergent to dry on the turn signal lenses will cause them to crack. Each Isuzu vehicle is originally equipped with an Owner's Manual that includes guidelines for the proper exterior maintenance of the vehicle. The following guidelines are typical of those found in an Isuzu Owner's Manual concerning the use of detergents on a vehicle's exterior.
• 10225520All engines require oil to lubricate and protect the load bearing and internal moving parts from wear including cylinder walls, pistons, and piston rings. When a piston moves down its cylinder, a thin film of oil is left on the cylinder wall. During the combustion process, part of this oil layer is consumed. As a result, varying rates of oil consumption are accepted as normal in all engines. The purpose of this bulletin is to describe different instances where oil consumption occurs and to make available a worksheet to assist the technician in determining if oil consumption is excessive.
• 10222330Some customers with N-series vehicles may notice an audible clicking or chattering noise coming from the rear of the vehicle while making tight turns. This condition may be due to incorrect axle fluid having been used during the last scheduled maintenance or in a previous repair. The condition can also result from delayed or skipped maintenance resulting in degradation of axle fluid.
• 10218932Isuzu Commercial Truck of America, Inc. (ICTA) is providing the following procedural recommendations to improve dealer efficiency when submitting Parts Warranty claims. We strongly recommend dealers follow these procedures in order to avoid delays in Parts Warranty claim payments and/or claim chargeback. This bulletin was revised to add a Parts Warranty Form
• 10218927Isuzu Commercial Truck of America, Inc. (ICTA) is providing the following procedural recommendations to improve dealer efficiency when submitting Parts Warranty claims. We strongly recommend dealers follow these procedures in order to avoid delays in Parts Warranty claim payments and/or claim chargeback.
• 10218926This bulletin is being written to inform technicians about the new Steering Angle Sensor in the affected vehicles and the importance of performing the relearn procedure after replacing the sensor or other steering related components that could cause the sensor angle to change. This sensor's position is initially learned by the Electric Hydraulic Control Unit (EHCU) during initial factory installation. The relearn procedure is done in order for the Electronic Stability Control and, if equipped, the Advanced Driver Assistance System (ADAS) to function correctly after steering wheel components (including but not limited to the Steering Angle Sensor) are replaced. If the sensor is replaced or if any component that affects the alignment of this sensor is replaced or adjusted, the Steering Angle Sensor position must be relearned by the EHCU. Below is a short list of components that, if replaced or adjusted, will require the Steering Angle Sensor to be relearned.
• 10217006Isuzu Motors Limited has decided that a defect exists in certain 2022 model year Isuzu NQR and NRR trucks (equipped with 6.0L gasoline engines) built before November 3, 2021. In the affected vehicles, the engine wiring harness assembly was incorrectly wired at the pinout connector for the oil pressure sensor. The ECM (and a technician's scan tool) will not detect the condition for low oil pressure and will always perceive the pressure to be at 126 PSI. If the oil pressure drops below a certain level, the engine oil pressure telltale will not illuminate to indicate low pressure. If the engine oil pressure is low, the defect will mask the warning to the driver or consumer, who may continue to operate the vehicles with a low engine oil pressure. If the engine continues to operate at the low engine oil pressure, it could damage the engine or its components and could cause the engine to seize and stall without prior warning. A seized engine can result in vehicle stalling and increase the risk of a crash.
• 10217004The Isuzu Commercial Truck of America (ICTA) Service Technical Assistance Center (TAC) provides diagnostic support to Isuzu dealer technicians repairing Isuzu vehicles in and out of vehicle warranty. A TAC case number will be issued solely for information tracking purposes and future contact reference.
