Procedure
1. Clean the ADC Sensor on every call.
2. Enter Diagnostics and select dC135.
3. Perform the Service Actions in Table 1 for any High Frequency Service Item (HFSI)
counters that are over threshold or approaching the threshold. Using the customer's out-
put volume numbers (high, medium, or low volume), evaluate which HFSI actions should
be accomplished now to avoid an additional service call in the near future.
