3. Diagnosis and Testing

– Refer to the DTC tables for the diagnostic repair procedures.
– Switch the ignition off.

3.3.4

Diagnostic Mode 04 - Erase DTC Mem‐

ory

Diagnostic Mode 04 makes it possible to erase the DTC memory

and to reset all emission related diagnostic data. In that way, all

faults in the DTC memory in the ECM and TCM are erased. The

adaptation values may also be reset.
Emission related diagnostic data includes (as applicable):
♦ - MIL status
♦ - Number of DTCs
♦ - Readiness bits
♦ - Confirmed DTCs
♦ - Pending DTCs
♦ - DTC that belongs to freeze frame
♦ - Freeze frame data
♦ - Test results of specific diagnostic functions
♦ - Distance driven with MIL on
♦ - Number of warm-up cycles after erasing the DTC memory
♦ - Distance driven after erasing the DTC memory
♦ - Misfire counter

Note

Depending on the scan tool and protocol used, diagnostic mode

04 and the information provided may be referred to by a different

name.

Procedure
– Connect the scan tool.
– Switch the ignition on.
– Select Diagnostic Mode 03: Interrogating fault memory.
– Then select Mode 4: Reset/delete diagnostic data.
The scan tool will display ”Diagnostic data being erased”.
– Switch the ignition off.

3.3.5

Diagnostic Mode 05 - Read Oxygen

Sensor Monitoring Test Results

Note

Mode 05 may not be supported on all systems. On systems where

Diagnostic Mode 05 is not supported, refer to Diagnostic Mode 6

for oxygen sensor monitoring test results.

Test Requirements
– No Test requirements are available for this powertrain.

Diagnostic Mode 06 - Read Test Results

for Specific Diagnostic Functions, 2014

- 2015 MY’s

Diagnostic Mode 06 makes it possible to retrieve test results for

special components and systems which are continuously or not

continuously monitored. If the diagnosis of a system is complete,

the diagnostic result and the corresponding thresholds are saved

and displayed in mode 06. This data remains saved (even with

the ignition off) until either new diagnostic results become avail‐

able or the DTC memory is erased.
The min & max values for each individual test in Mode 06 repre‐

sent the min & max operating values for a properly operating

system. This data is provided to the individual aftermarket scan

tool companies for development of their scan tool. Depending on

the scan tool being used, the min & max values shown may vary,

or be rounded up or down to the nearest decimal point depending

on the aftermarket scan tool company's development process.
For example; GST manual documentation will show the value as

0.3499 (units) while the scan tool will display the same value as

0.35 (units).
Depending on the scan tool and protocol used, the information

displayed in Diagnostic Mode 06 may be referred to by different

names such as Test-ID (TID), Hex-ID, Component-ID (CID), On-

Board Diagnostic Monitor Identifier (OBDMID), or contain no

name at all and may be referenced by only a number.
Test requirements
• Exhaust system must be properly sealed between the catalytic

converter and the cylinder heads.

• No DTCs stored in the DTC memory.
• Coolant temperature at least 80° C.
Work procedure
– Connect the scan tool.
– Start the engine and let run at idle speed.
– Select Mode 6: Check test the results of components that are

not continuously monitored.

Select the desired Test-ID.
The current minimum and maximum values will be displayed on

the scan tool screen.
