Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.

CAN = Controller Area Network
P1 and P2 CAN module recovery (does not apply to P3 CAN modules or any MOST modules):
A CAN module which no longer responds on the network due to a failed or interrupted download can usually be recovered. This procedure assumes the module is not entering programming mode due to a download error, not because of a hardware or vehicle issue.
When a CAN module is supplied with power, it always starts in programming mode, then goes into its normal running mode after a very short period of time (20 milliseconds). If the module receives a PROG command during this start-up phase, it will remain in programming mode instead of continuing to its normal running mode. The attached procedure provides a PROG command during this start-up phase which keeps the module in programming mode.
When SEND PROG is chosen, the button changes to STOP PROG.
It is important to be aware of this, as clicking twice in a row will result in stopping the PROG command.
When SEND PROG is chosen, there is a slight delay and the hour glass is shown instead of the cursor. Once the hour glass disappears, VIDA continually sends a PROG command until some other action is taken (STOP PROG, READ HW NUMBER, READ SERIAL NUMBER, etc). This function is reliable in current VIDA versions and prevents the need for any time-critical procedure used earlier.
Due to a large number of variables (vehicle platforms, software types, hardware types and failure modes) this procedure will not work in all cases.
The attached procedure is a one page document suitable for printing.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
