Situation:

In order to determine which vehicles are being monitored, it will be necessary to utilize the "Service Menu" of the DCS (Dealer Communication System). Based on a positive response of the system, follow the procedure outlined below.

Note:
Once the set quantity of camshaft sensor to be used for analysis is met, all vehicles will be removed from DCS, indicating the end of this measure.

Procedure:
1. Inform the customer that the camshaft sensor will be removed from the vehicle and obtain the customer's consent.

2. Have the customer sign and date the form attached to this bulletin BEFORE you remove the camshaft sensor. The signed form should be filed with the repair order. The attached blank form should be copied as needed.

3. Read and print out DME fault codes if present.

4. Ignore any camshaft sensor fault codes if present.

5. Clear all fault codes stored in the DME.

6. Replace camshaft sensor.
Note: Since the removed camshaft sensor will be used for further analysis, avoid damage to the sensors during shipping by packing them into the boxes the new ones came in, covering the tips with the protective cap.
