ISSUE

Content 

During the P046 campaign, the Occupant Classification Module software update may fail.

CAUSE

Due to the Electrically Erasable Programmable Read-Only Memory (EEPROM) fault that the P046 campaign is designed to fix, some modules may fail to respond correctly to an SDD programming request.

ACTION

In the event of the software update failing, please follow the instructions below starting with 'Method 1'
