POST REPAIR PROCEDURES
Table 10-1 Post Repair Procedures lists the required procedures that must be performed
after the replacement of an assembly or the EEPROM. These are the recommended
minimum procedures to ensure that the replacement is successfully completed.
When you replace an assembly or the EEPROM on the A1 CPU, perform the adjustments
and updating correction constants (CC) in
Table 10-1. Then perform the operational
verifications and performance verifications listed in Table 10-1.
For the detailed procedure of the adjustments and updating correction constants, see
Adjustments Chapter. For the detailed operational verification procedures, see this manual's
chapter specified in
Table 10-1. For detailed performance verification procedures, see
Performance Test Chapter in this manual.
