GENERAL INFORMATION FOR ON BOARD DIAGNOSTIC (OBD) 

Characteristics of On Board Diagnostic (OBD) 

The control module for Diesel-Direct fuel injection system is equipped with a DTC memory. 

If malfunctions occur at the emission relevant systems or components, they are stored in DTC memory with a 
description of the malfunction type. 

The control module for Diesel-Direct fuel injection system differentiates between different DTCs after 
evaluating the information. See DIAGNOSTIC TROUBLE CODE (DTC) TABLES: . 

The stored malfunctions can be checked with a standard diagnostic tester. See DIAGNOSTIC MODE 3: 
CHECK DTC MEMORY . 

When harness connectors are disconnected from the control module for Diesel-Direct fuel injection system or 
the battery is disconnected, all adaptation values in the control module are erased. DTC memory content will 
remain intact however. If the engine is started after this, rough, uneven idle can result. In this case, the readiness 
code must be generated again. See READINESS CODE, GENERATING . 

The following work steps must be performed in the described sequence after the malfunction(s) have been 
repaired: 

1. - Check DTC memory. See DIAGNOSTIC MODE 3: CHECK DTC MEMORY .  

2. - Erase DTC memory. See DIAGNOSTIC MODE 4: RESET/ERASE DIAGNOSTIC DATA .  

3. - For completion, generate readiness code. See READINESS CODE, GENERATING .
