The IR115 pin code is shared with several other OEX Denso alternators always confirm all mounting dimensions and mount type. Note that the DXA520 (70A, single leg, 5-groove, 164mm CTC) shares the same single leg mount style and 58mm leg thickness but has different output, CTC, pulley section and OD. The two are not interchangeable.

First, if replacing an 85A alternator with this 130A unit, upgrade the battery cable and fuse between the alternator and battery to handle the increased current. Second, if the alternator warning lamp flickers during acceleration or deceleration, the issue may be related to a faulty ECM rather than the alternator diagnose the ECM before replacing the unit again.

If the alternator warning lamp flickers during acceleration or deceleration, the supplier notes this may be related to a faulty ECM rather than the alternator itself. Diagnose the ECM before concluding the alternator is at fault.
What is the warranty on this alternator? 3 years for passenger vehicle applications, 1 year for commercial use.
What should I confirm before ordering this alternator? Confirm mount type (single leg), CTC (165mm), leg thickness (58mm), adjusting hole (M8x1.25), pulley section (7-groove), pulley OD (58mm), rotation (clockwise) and pin code (IR115) all match your vehicle's requirements.
