the voltage CAN H & CAN L to the RTN it is 2.5 VDC when power on.
- I check the EN-CARIO in M1311 is =7 i think it is ok because PRS and RSL are connected to the TOCB.
- Remaque when i cycle the power on the TOCB CAN led flashing just 5s and remain off.
- The TOCB RSL & POWER LEDs are flashing i think thats ok.

If anyone have more details about the error code 0040 CarioComErr .. Plz let me know.
