Reason for block
Complaint:
Loss of Power and Check Engine Light with Fault Codes P15FF00 or P245411
Cause:
Engine control unit connection (CR60NFZ).
Remedy:
Important: Do not replace engine control unit, differential pressure sensor and engine wiring harness!
If fault codes P15FF00 or P245411 are stored in the engine control unit (CR60NFZ):
1.
Run initial quick test.
2.
Visual Inspection: Line condition in area of differential pressure sensor (sensor up to diesel particulate filter) as
well as check of electrical connections and wiring up to branch-off line for engine wiring harness.
3.
If there is no issue found with any of the components mentioned in test step 2, please remove the engine control
unit (see AR07.08-D-7006SD).
4.
Clean contact pins on engine control unit as per operation steps 4.1 to 4.4:
4.1 A total of 154 contact pins have to be cleaned on the engine control unit (see 1.jpg).
Important: One cleaning contact is sufficient to clean all the contact pins in a color-marked area (see 2.jpg and
3.jpg).
4.2. Apply cleaning fluid to cleaning contact. Avoid forming droplets! It need only be applied once to clean the
specified number of pins per cleaning contact (see 4.jpg).
Warning: Please observe the applicable operating instructions and safety information for this product when
handling cleaning fluid.
4.3 The cleaning contact is used for 2 contacts at the same time on the small contact pins. Clean pins by moving
up and down 2 times in succession. Slide cleaning contact onto pins until the cleaning contact impacts with the
multipoint connector housing (see 5.jpg, 6.jpg and 7.jpg).
Warning: If the cleaning contact is tilted, adjacent contacts may be damaged or bent.

Important: Cleaning fluid volatilizes immediately after the cleaning process. This means that installation of the
cable sets for the engine control unit can be commenced immediately after the cleaning process.
4.4 Install engine control unit (see AR07.08-D-7006SD).
5.
6.
7.
Warning: Care should be taken prior to installation to ensure that the contacts do not exhibit any signs of deformation. Deformation may lead to contact problems in the engine control unit that then render the engine control
unit unusable!
If cleaning the contact pins does not remedy the problem, the differential pressure sensor repair wiring harness
(A 642 150 80 01) must be installed. Use approved end sleeves.
Fasten differential pressure sensor plug under engine control unit to vehicle wiring harness using cable tie
across center of plug housing (see 8.jpg and 9.jpg.).
Erase fault memory.
If this is a repeat repair:
1.
Run initial quick test.
2.
Create a PTSS case and attach the following documents:
•
Quick test 1: First workshop visit # Clean contact pins on engine control unit
•
Quick test 2: Current quick test with fault freeze frame data
