TROUBLE CODES
Required Special Tools:
• MB991958: Scan Tool (M.U.T.-III Sub Assembly)

If detecting the malfunction during the first drive cycle, the ECM
temporarily stores the diagnosis code as the provisional diag-
nosis code. If detecting the same malfunction during the next
drive cycle, the ECM determines that the malfunction exists.
The ECM outputs the diagnosis code. On Scan Tool
MB991958, it is possible to display the stored provisional diag-
nosis code which the ECM had detected during the first drive
cycle. This makes it possible to confirm in one drive cycle
whether the malfunction could happen again after the repair.
