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

Dodge P2609

Basic error definition

Mode Indicator 1. General Electrical Failures. Circuit Short To Ground

Cause of DTC

There is a position indicator in the switch for the Four-C function for each selectable drive mode. Each position indicator is individually supplied with power from the Suspension module (SUM) and is ground via a common ground lead to the Suspension module (SUM). When selecting the drive mode in the switch, the corresponding position indicator of the control module is activated. The diagnostic trouble code (DTC) is stored if the control module detects that: Voltage to the position indicator is too low. The control modules test for the diagnostic trouble code (DTC) starts in the event of: Ignition switch position II, when the corresponding switch is activated. 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). The diagnostic trouble code (DTC) indicates the relevant position indicator. SUM-C112C11: Position indicator 1. SUM-C112D11: Position indicator 2. SUM-C112E11: Position indicator 3.
