What does CP-A049 mean?
Tesla alert code in the Charge Port (CP) module. Multiple charge cables detected The CP detects both AC and DC GB charging cables The CP detects either one or no GB charging cable Silent alert for UHF faults during sleep The modem successfully booted into its application, but required the CP to reset it first Failed to establish comms with supercharger during SECC discovery Control pilot signal from charging station is lost while charging. Charging may be interrupted. info from manualCP_A055 Proximity is detected with no control pilot signal and no digital communications while the vehicle is charging. Lost communication with HVLINK Charge port does not receive all expected CAN messages from the HVLINK Charge port receives all expected CAN messages from the HVLINK The CP uses this for specfic exceptions triggered in code, like data exceptions or machine check errors 12V supply undervoltage, cannot charge The CP's measured 12V supply reads less than 8V The CP's measured 12V supply reads above 8V Proximity circuit was opened unexpectedly while charging. Charging may be interrupted. info from manualCP_A056 The charge port (CP) detects that there is no charge cable present while the vehicle is charging. Any charge port (CP) door sensor detects that the door is closed. Door hall effect sensor is out of range (Gen 1 EU only) Door hall effect sensor reading is out of expected range for more than five seconds Door hall effect sensor reading is within expected range for more than one second Inability to sense door presence Charge port does not receive all expected CAN messages from the VCSEC Charge port receives all expected CAN messages from the VCSEC

Affected Tesla Models
What You May Notice
- Charge port alert: Multiple charge cables detected The CP detects both AC and DC GB charging cables The CP detects either one or no GB char
- Charging session may be interrupted or not starting as expected
- Charge port light flashing amber or red
How to Diagnose and Resolve
- 1 Unplug and re-plug the charge cable
- 2 Try a different charging cable or Supercharger stall
- 3 Reboot the vehicle and attempt to charge again
- 4 If "Multiple charge cables detected The CP detects bot" persists, contact Tesla Roadside Assistance
- 5 Schedule a Service Center visit if the problem continues
Severity Notes
CP-A049 is an Alert in the Charge Port system. Confirm the vehicle screen and Tesla app show no driving or charging restrictions, and schedule service if the alert returns.
