SITUATION
The engine will not crank or the engine loses power while driving, followed by a no crank
situation. There is no communication with the DME when diagnosing with ISTA (DME is yellow
on control unit tree).
CAUSE
In certain instances, the startup of the turbocharger coolant pump can exceed the 5A rating of fuse
F83.
CORRECTION
Check and replace/retrofit fuse F83 with a “7.5A capacity fuse” and verify the turbocharger coolant
pump’s operation.
PROCEDURE
Check fuse F83 (5A) for activation “blown”.
Is fuse F83 (5A) blown?
YES- replace with a 7.5A fuse and perform a functional check of the turbocharger coolant pump
using test plan ABL-DIT-AT1214_BX8_TKMP – Turbocharger coolant pump in ISTA. If the
pump operates normally, no further repairs are necessary.
Or:
NO- follow standard diagnostic procedure with ISTA/D.
