Combinations of Fault Codes
Combinations of fault codesThe following tables show the combinations of fault codes which may be obtained when the ETS and ASR control unit circuits have no continuity or are shorting to earth. All faults should be traced to the control unit side in the relevant circuit.
It will be seen in the table that 25771 and 25772 are often generated as consequential faults in the LH system, but other fault codes may also occur. Remember to clear these consequential faults in other systems also when the main fault has been remedied.
Note: Tests (shorting to +12V) have been carried out only on the pins marked in the corresponding table columns, either by the relevant fault code or by *NO*.
