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

Component group: 

z

Pxxxx = DTC for drivetrain  

Norm-Code: 

z

P0xxx = DTCs defined by SAE with specified malfunction texts  

z

P1xxx = additional emission relevant DTCs provided by manufacturer  

z

P2xxx = DTCs defined by SAE with specified texts, from MY 2000  

z

P3xxx = additional emissions relevant DTCs provided by manufacturer from MY 2000  

System group: 

z

Px0xx = Fuel and air ratio and additional emission regulations  

z

Px1xx = Fuel and air ratio  

z

Px2xx = Fuel and air ratio  

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 CONNECT DIAGNOSTIC TESTER .  

z

Start engine and let run at idle.  

z

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

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

SAE P1xxx-DTCs. See SAE P1XXX-DTCS .  

z

SAE P2xxx-DTCs. See SAE P2xxx-DTCs .

Display example: 

P0444 Evaporative Emission (EVAP) Canister Purge Regulator Valve -N80- Open circuit 

Explanation: 

z

P0444 = SAE diagnostic trouble code (malfunction identification number)  

z

Evaporative Emission (EVAP) Canister Purge Regulator Valve -N80- malfunctioning wiring path or 
malfunctioning component  

z

Open circuit = Malfunction type as text 

NOTE:

Only if engine does not start:

NOTE:

z

The DTC table is sorted by SAE code.  

z

"E-Gas"-relevant malfunctions are also indicated by the warning lamp for 
Electronic Power Control ("EPC warning lamp") in the instrument cluster.  

z

"Emission"-relevant malfunctions are additionally indicated in the 
instrument cluster via the Malfunction Indicator Lamp (MIL).  

z

In Diagnostic mode 2, it can be determined at which operating condition a 
malfunction was detected and stored by the Engine Control Module (ECM). 
See DIAGNOSTIC MODE 2: CHECKING OPERATING CONDITIONS .  

z

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

Diagnostic mode 4: Reset/erase diagnostic data

Function 

This diagnostic mode performs the following functions: 

z

all emission relevant malfunctions in DTC memory will be erased,  

z

the operating conditions at which a malfunction was stored will be reset. See DIAGNOSTIC MODE 2: 
CHECKING 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 CONNECT DIAGNOSTIC TESTER .  

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

Generate readiness code. See READINESS CODE, GENERATING .  

Diagnostic mode 5: Check output of oxygen sensor signals 

Function 

The static values of the oxygen sensors are indicated via this diagnostic mode. 

The values of the individual oxygen sensor signal outputs must reach the specified value or must be within the 
min.- and max.-limits. 

Requirements 

z

There must not be any DTCs stored in DTC memory. See DIAGNOSTIC MODE 3: CHECK DTC 
MEMORY
 .
