Diagnostic Mode 1 - PID Measured Values 

z

End diagnosis and switch ignition off.  

Diagnostic mode 2: Check operating conditions 

Function 

This diagnostic mode displays the operating conditions at which an emission relevant malfunction was detected 
and stored by the control module for Diesel-Direct fuel injection system. 

Work procedure

If DTCs are displayed in "PID 02": 

z

Repair stored malfunctions according to DTC table:  

z

SAE P0xxx-DTCs. See SAE P0xxx-DTCs .  

z

End diagnosis and switch ignition off.  

Diagnostic mode 3: Check DTC Memory 

Function 

This diagnostic mode indicates all stored DTCs of components and systems which are emission relevant. 

Malfunction Indicator Lamp (MIL) in instrument cluster lights up for one DTC entry. See MALFUNCTION 
INDICATOR LAMP (MIL) IN INSTRUMENT CLUSTER
 . 

SAE Diagnostic Trouble Codes (DTCs) 

The DTC always consists of a 5-digit alpha-numeric value with the following meaning: 

Component group: 

z

P0xxxx = DTC for drivetrain.  

Norm-Code: 

z

P0xxx = DTCs defined by SAE with specified malfunction texts.  

System group: 

z

Px0xx = Fuel and air ratio and additional emission regulations  

z

Px1xx = Fuel and air ratio.  

z

Px2xx = Fuel and air ratio.  

02:

DTC which triggered the current reception of all control module information

04:

Calculated load condition value

05:

Coolant temperature

11:

Intake manifold pressure

12:

Engine rotations per minute (RPM)

13:

Vehicle speed

14:

Valve timing adjustment at 1. cyl. to "advance"

15:

Intake Air Temperature (IAT)

16:

Air flow quantity at Mass Air Flow (MAF) sensor

17:

Throttle valve position (absolute)

z

Px3xx = Ignition system.  

z

Px4xx = additional emission regulation.  

z

Px5xx = Speed and idle control.  

z

Px6xx = Control module and output signals.  

z

Px7xx = Transmission.  

z

Px8xx = Transmission.  

z

Px9xx = Control modules, input and output signals.  

Work procedure 

z

Connect diagnostic tester. See DIAGNOSTIC TESTER, CONNECTING .  

z

Start engine and let run at idle.  

z

Under address word 33, select "Diagnostic mode 3: Check DTC memory."  

The number of stored malfunctions or "0 malfunctions detected" is displayed. 

z

End diagnosis and switch ignition off.  

z

Repair stored malfunctions according to DTC table:  

z

SAE P0xxx-DTCs. See SAE P0xxx-DTCs .  

z

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

Display example: 

P0183 Fuel Temperature Sensor A Circuit High

NOTE:

Only if engine does not start: 

z

Operate starter for approx. 6 seconds. Do not switch ignition off afterward. 

NOTE:

z

The DTC table is sorted by SAE codes.  

z

"Emission"-relevant malfunctions are additionally indicated in the 
instrument cluster via the Malfunction Indicator Lamp (MIL). See 
MALFUNCTION INDICATOR LAMP (MIL) IN INSTRUMENT CLUSTER .  

z

In Diagnostic mode 2, it can be determined at which operating condition a 
malfunction was detected and stored by the control module for Diesel-
Direct fuel injection system. See DIAGNOSTIC MODE 2: CHECK 
OPERATING CONDITIONS .  

z

Explanation: 

z

P0183 = SAE diagnostic trouble code (malfunction identification number).  

z

Fuel Temperature Sensor A = faulty circuit or malfunctioning component.  

z

Circuit High = malfunction type as text  

Diagnostic mode 4: Reset/erase diagnostic data 

Function 

This diagnostic mode performs the following functions: 

z

z

the operating conditions at which a malfunction was stored will be reset. See DIAGNOSTIC MODE 2: 
CHECK OPERATING CONDITIONS
 .  

z

all adaptation values are being reset,  

z

all test results of the diagnostic functions are being reset.  

Requirement 

z

DTC memory was checked. See DIAGNOSTIC MODE 3: CHECK DTC MEMORY .  

Work procedure 

z

Connect diagnostic tester. See DIAGNOSTIC TESTER, CONNECTING .  

z

Start engine and let run at idle.  

z

Under address word 33, select "Diagnostic mode 4: Reset/erase diagnostic data."  

Erased or reset: 

z

Number and content of the DTC memories,  

z

Operating conditions,  

z

Adaptation values,  

z

Test results.  

z

End diagnosis and switch ignition off.  

z
