3.2.2 AFTER INSTALLING THE NEW PM PARTS
1. Turn on the main power switch.
2. Output the SMC logging data with SP5-990-004 and check the counter values.
3. Make sure that the PM counters for the replaced units are “0” with SP7-803. If the PM
counter for a unit was not reset, then reset that counter with SP 7-804.
4. Make sure that the exchange counter counts up with SP7-853.
5. Make sure that the counters for the previous units (SP7-906) on the new SMC logging
data list (from step 2 above) are equal to the counters (SP7-803) for these units on the
previous SMC logging data list (the list that was output in the “Before removing the old
parts” section).
6. Make sure that the unit replacement date is updated with SP7-950.
