On this test drive the technician will do their best to have similar conditions to the freeze frame data. The first step is hooking up a scan tool to check for any codes stored in the ECU, with any of the codes will be the DTC freeze frame data which tells us the engine coolant temp, vehicle speed, RPM, load and etc.Ĭodes will then be cleared and a test drive performed. How does a mechanic diagnose the P2015 code?
In some vehicles the engine may idle poorly and have a lack of power under acceleration. Most vehicles will exhibit the Check Engine Light and that will be the only symptom.

This causes a failsafe mode to be enabled which will remain till normal operation is found or the code is repaired. When this occurs, the ECU detects the out of range performance as it is looking for a specific values and when they are not seen the DTC P2015 is set. The P2015 code means that there is out of range performance from the bank 1 intake manifold runner position sensor. 72 volts you need to adjust the stepper motor nut ( Do not mess withthe Primary TPS just the 7 mm bolt on the bottom of the stepper motor.P2015 is a generic OBD2 diagnostic trouble code point at a malfunction with the intake manifold runner position circuit. 72 volts on your screen and at the bottom it will tell you if it is not.
60 volts you will double click on the Adjust ISCV button again and the stepper motor will move. The written instructions for each step in the procedure are on the bottom of the tune ecu screen follow them do not deviate. 60 volts use the gauge on the screen to read the volts. see belowĭouble click it and a box will show up asking you if you want to perform the reset click yes or ok and it will move the stepper motor all the way back and tell you to check and set the Primary TPS to. 72 volts you need to adjust the stepper motor nut ( Do not mess withthe Primary TPS just the 7 mm bolt on the bottom of the stepper motor. Once on the test tab go to the second from the bottom left of the tune ecu screen Adjust ISCVĭouble click it and a box will show up asking you if you want to perform the reset click yes or ok and it will move the stepper motor all the way back and tell you to check and set the Primary TPS to. With bike linked up an dnot running go to TEST tab upper right corner of tune ecu NOT the DIAGNOSTICS tab and not the MAP EDIT tab. Once you are linked up you need to do a complete ISCV reset anything else will not be right NO SHORT CUTS.
Now to set it up you need to link up with the bike see below.ġst plug cable into computer first and listen for dadonk as the computer recognizes the cable.Ģnd plug cable into bike look for the light if yours has one.ģrd Key switch to 'on' and handlebar kill switch to 'run' position but do not start the engine.Ĥth open Tune ECU and watch for the green TPS light as you link up.
