Why does the exact Tesla alert ID matter?

Record the exact alert ID, including underscores, suffixes, and companion alerts. Tesla alerts that look similar can point to different modules, timestamps, and service procedures.

What does ELECTRONIC-PARKING-BRAKE-HAS-IDLEFAULTOR-1 mean?

Tesla unknown code in the ELECTRONIC (ELECTRONIC) module. Electronic Parking Brake caliper motor may be disconnected (idle fault), or no csm requests during retry/fault Non user facing alert set for service set when winch mode is active Electronic Parking Brake not sure if it is a left or a right. Motor positive lead voltage is higher than expected while active The positive lead voltage measurement is higher than expected. This could be higher than 0.1 voltages if motor is driven in release direction, or higher than estimated PWM voltage if driven in the apply direction. One or more of the expected CAN messages from UI were not received. One or more of the expected CAN messages from RCM were not received.
