CSP5 Switch Installation
Plug in the switch into the device.
It will start by blinking the firmware version number, a series of long and short blinks.
Turn the key on and change the tune and it will blink the tune it just set.
Test all the positions. If it correctly blinks the tune number in each position, then it’s working perfectly.
If it doesn’t work in position five or in positions 3-5, you most likely only have two or four tunes and should follow the directions for moving the tabbed washer.
Once you’ve determined it’s working, finish installing it.
Unless you have a mounting bracket, installing the switch requires the drilling of two holes, one small and one large. If you don’t want to drill the second hole, you may cut off the anti-rotation pin, so you don’t need the small hole.
After routing wire and before installing the switch, please use included tie wrap to secure the black jacket of the cable to the switch using the small slot in the corner of the PCB. This prevents wires from getting pulled out of the connector or the connector getting pulled free.
Your switch has a nut and two washers. The smooth washer must remain on the bottom with the tab located in hole number five*. If it falls out, turn the switch fully counter clockwise and place the washer back with the pin in hole number five. Make sure the switch moves exactly four clicks clockwise. If not, turn the switch back fully counterclockwise, move the pin, and try again.
*If you have a CSP2 or CSP4 tune, follow the instructions in the previous paragraph but place the tab in hole number two or four, (instead of hole number five.)
For 2018+ and if you use EFILive®, you will also need a Cummins Bypass Cable to flash (and to use the CSP5 switch). And, you MAY also need it for MM3, Smarty & RME if the security module fails.
