Technical Service Bulletin
Tip: Fault codes and symptom codes must match exactly or this TSB should not be followed. Instructions for
obtaining the symptom codes are in the Service section of this bulletin.

Technical Background
Poor internal contact area on circuit board will lead to faults. Oil additives can cause the plastic circuit plates to
delaminate, causing contact loss.

Production Solution
Improved circuit board for mechatronics unit.

Service
Confirm that this TSB applies by checking the symptom code:
1. Check the DTC memory. The symptom code is listed with the DTC (Figure 1).

Figure 1. DTC memory with symptom code.
2. If the DTC is listed in the Condition section of this bulletin, and it has the corresponding symptom code from the
list, perform the repair that follows.
