Diagnostic Trouble Code (DTC) Memory (CF) - Section 12
Preparation for Test:
1. Fuses ok,
2. Ignition: ON
3. Connect the Hand-Held Tester (HHT) to x11/4, according to diagram, see section 0. Connection and Use of Test Equipment - Section 0
4. Voltage supply to control modules and CAN data lines ok. See CAN, Section 23. Testing and Inspection
5. All CAN data lines must be connected properly.
NOTE: The diagnostic trouble codes (DTC's) can only be read out and erased using the Hand-Held Tester (HHT).
DTC's for one particular system may be stored in other control modules, therefore readout the DTC's from all other relevant control modules as well. When reading out DTC's, all stored DTCs will appear, which means that some of the DTCs that appear, will not be relevant to the system being checked. Non-relevant DTCs will be described in the particular system.
Special Tools:
Note regarding DTCs
Only those DTCs as noted below, are relevant for the convenience feature system.
Current diagnostic trouble codes are highlighted in black on the display. Additional detailed fault information based on fault type is displayed with nearly all diagnostic codes (DTC's) such as:
> ohm resistance too great
< ohm resistance too low
[]+ short circuit to positive (POS)
[]- short circuit to ground (GND)
-//- open circuit
With some fault codes, additional information as well as fault frequency can be read Out.
Fault frequency
Faults are noted by frequency of occurrence, i.e.: 4 periodic faults, 4 occurances.
