See the basic definition of a diagnostic error. This will help you to clarify the main causes of the fault code. You will understand the program of the control unit
Basic DTC analysis according to OBD2 protocol standard.

OBD2 or On-Board Diagnostics displays messages for basic group styles. More comprehensible code composition has been standard since 2000. The DTC code consists of five characters and its composition will be shown in this video

Insight into programming

The basic unit for the operation of any computer is the bit. Logic 0 and 1 are expressed by a single bit. Diagnostics The error code is composed of 16 bits. The first two bits define one of the four basic circuits. The video will show you a comprehensive overview of the composition of the error report

A diagnostically understandable description of the Diagnostic Trouble Code

GMC P1AE3

Basic error definition

Invalid Data Received From Brake Control Module. Algorithm Based Failures. Event Information

Cause of DTC

Note! This diagnostic trouble code (DTC) status is an event controlled diagnostic trouble code (DTC). An event controlled diagnostic trouble code (DTC) does not mean that there is a fault in the control module when it is active, but is designed as information. These diagnostic trouble codes (DTCs) do not need to be erased but disappear when the conditions no longer apply. The Suspension module (SUM) continually receives information from the Brake control module (BCM) via CAN communication. Information is checked by the Suspension module (SUM). The diagnostic trouble code (DTC) is stored if the control module detects that: A message indicating that yaw angle or lateral acceleration from the Brake control module (BCM) is incorrect or invalid. The control modules test for the diagnostic trouble code (DTC) starts in the event of: Ignition switch position II. The test is carried out every other operating cycle. The Suspension module (SUM) defines an operating cycle as ignition on and ignition off. Note! The control module can only detect the fault once the test has been started and the diagnostic trouble code (DTC) is stored when the conditions are met. Note! When diagnostic trouble codes in the suspension module (SUM) are erased, they do not disappear until the next operating cycle (ignition off - ignition on).
