VCFRONT-PTGOTOSLEEP-1
VCFRONT_ptGoToSleep_1
What does VCFRONT-PTGOTOSLEEP-1 mean?
Tesla unknown code in the Vehicle Controller Front (VCFRONT) module. All messages the local ECU expects to receive from the ESP ECU are being received or the ESP ECU is CAN inactive. Stability and traction control functionality may be missing. One or more of the expected CAN messages from VCSEATD were not received. A message the local ECU expects to receive from the VCSEATD ECU hasn't been received within the expected timeout or the drop rate is too high while the VCSEATD is CAN active. The ECU is considered CAN active when VCFRONT_chGoToSleep is 0. All messages the local ECU expects to receive from the VCSEATD ECU are being received or the VCSEATD ECU is CAN inactive. VCSEATD functionality may be missing. The battery voltage measurement, nominally 12 volts, was higher than expected. The vbat voltage measurement is higher than 18.5 volts. One or more of the expected CAN messages from CHG were not received. A message the local ECU expects to receive from the CHG ECU hasn't been received within the expected timeout or the drop rate is too high while the CHG is CAN active. The ECU is considered CAN active when VCFRONT_ptGoToSleep is 0. All messages the local ECU expects to receive from the CHG ECU are being received or the CHG ECU is CAN inactive. CHG functionality may be missing. Electronic Parking Brake release was interrupted. Release will be retried.
