Technical Service Bulletin
Production Solution
There is a concern with the aluminum shielding on the PODS harness under the seat that is causing the DTC
B1225F1 to occur. The aluminum sleeve isn’t fitted tight enough to the harness, a small amount of interference is
possible and causes the fault.
The service solution is to apply cable ties at two different points of the harness under the seat which tightens the
fit of the aluminum shielding and corrects the issue.

1. Do not follow this TSB. Please perform Campaign 74E3 instead.
Q7
1. To apply the cable ties, the seat does not need to be removed. You will need to move the lateral seat
adjustment all the way to rearmost adjustment limit and the vertical height adjustment all the way to the
upper adjustment limit.
Once the seat is adjusted to the above-mentioned position, you will see the need to attach the cable ties at
two points on the harness as shown (Figure 1).
