SOTF Duramax DSP5 Switch Information

To verify the functionality of your SOTF ( switch on the fly ) switch please try the following.....

<span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">To verify the functionality of your SOTF ( switch on the fly ) switch please try the following<span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:700;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">1 ) View this link :<span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">&#xA0;<a href="https://www.fishtuning.com/troubleshootingswitches" style="text-decoration:none;"><span style="font-size:11pt;font-family:Arial;color:#1155cc;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:underline;-webkit-text-decoration-skip:none;text-decoration-skip-ink:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">https://www.fishtuning.com/troubleshootingswitches</a><span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:italic;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">Check to see if there is a button on the back of the switch. If so, with the key on, press the button at each position and note the results. When you press the button a small LED may light up. It should be brightest in position one (fully counter-clockwise) and dimmest or off in position five (fully clockwise). Except for some Fords which will be bright in both positions one and five. There should only be five positions. If that happens then the switch is probably installed correctly and working properly.<span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:italic;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">If you still think it&apos;s not working, or you have a switch without a button on the back, you can test the switch with a voltmeter across the wires with the key on. You can get to the wires from the back of the switch. Starting in position one you should see a voltage, most commonly 5V DC or so, and then as you go from position one to position five, the voltage should drop. If that happens then the switch is probably installed correctly and working properly.

I think My SOTF Switch is not working..

You can install the SOTF switch at any time. Before or after the tune installation is good! I would suggest you install the tunes first to see if the installation went OK, then install the switch ( but it makes no difference )

<span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">You can install the SOTF switch at any time.<span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">It is not required for you to install if you are not wanting to use the switch.&#xA0;<span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">I<span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">f you do not install the switch, it will act as if it is on position 1 (+0HP).<span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">You can install the switch before or after the tune installation. If you plan on installing the switch and have not installed the tunes yet&#x2026; Feel free to do the switch install after you get the tunes on. First check if the tunes were loaded on with no problems, then install the switch.<span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">If the switch does not seem to be working, reflash the tune file again. If any error occurs or if you think the switch is not working, let us know by sending a support ticket here : &#xA0;<a href="https://form.jotform.com/223478868814068" style="text-decoration:none;"><span style="font-size:11pt;font-family:Arial;color:#1155cc;background-color:transparent;font-weight:700;font-style:normal;font-variant:normal;text-decoration:underline;-webkit-text-decoration-skip:none;text-decoration-skip-ink:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">Create support ticket</a><span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">&#xA0;
