041-323 MCU PWB Fuse F5
Fuse F5 on the MCU PWB has an open circuit failure.
Procedure
Perform the following:
• Check the connection of each MCU PWB electrical connector.
• If any service was performed immediately before the fuse failure check that no wire dam-
age was caused in the areas that were serviced.
• Check the harness wires for damage on the following BSD’s; 1.2A, 4.1A, 6.5, 7.7, 7.9,
8.1, 8.2, 8.7, 9.2, 9.3, 9.4A, 9.4B, 9.5, 9.6, 10.3, 10.5, 10.7.
• If no problems are found replace the MCU PWB (PL 11.1).
041-340 MCU PWB Data RAP
BSD-ON:3.1
There is a MCU PWB Data failure. Data storage address corruption occurred.
Initial Actions
Ensure that the MCU PWB E-PROM is secure on the MCU PWB (PL 11.1).
Ensure that the last software has been loaded.
Procedure
Check the connection of each MCU PWB electrical connector. The connectors are con-
nected correctly.
YN
Secure the connectors.
Turn on the power again. [041-340] persists.
YN
Return to Service Call Procedures.
Initialize NVM. [041-340] persists.
YN
Return to Service Call Procedures.
