    What does this fault code mean?

    With the ignition on, the ECM checks that it is receiving +30 supply. If that supply is missing, the fault ECM-8000 is stored, and the cause is an open circuit in the power wire. The malfunction indicator lamp lights. The fault applies to the C70 Convertible (-05), C70 Coupe (-02), S60 (-09), S70, S80 (-06), V70 (-00) and V70 (00-08).

    Possible causes

    • Open circuit in the power wire to the engine control module

    What you can do

    1. 1Read and note the code, clear it and road test to see whether it returns
    2. 2Check that the fuses for the engine control module are intact
    3. 3If you have a diagnostic tool: read the system voltage with the ignition on; it should be close to the battery voltage
    4. 4Inspect the power wire to the engine control module for breaks, chafing and loose connectors
    5. 5If the fault remains, have a workshop with diagnostic equipment check the wiring and the control module

    Symptoms you may notice1

    • The malfunction indicator lamp (MIL) is lit
