ECD SYSTEM FAIL-SAFE CHART

If any of the following DTCs are stored, the ECM enters fail-safe mode to allow the vehicle to be driven temporarily.

Tip:

PM regeneration may be prohibited depending on the malfunctioning part of the exhaust treatment system (DPF related portion).

*: If the Fail-Safe Deactivation Condition is "Ignition switch off", you must wait for 30 seconds or more after turning the ignition switch off.
