The DTC can be set when the vehicle is started and the battery voltage is too low. The
engine does start but the Motronic Engine Control Module (ECM) -J220- detects that the
voltage is too low. The battery must be recharged and the DTC memory erased. Then
Throttle Valve Control Module must be adapted (matched) to the Motronic Engine
Control Module (ECM) -J220- and the readiness code regenerated again. If the DTC
occurs again after a road test, then replace the control module.
