77-2-14 PROCEDURES
Electronic control units
The electronic control units (ECU) fitted to vehicles make it advisable to follow suitable precautions prior to carrying
out welding repair operations. Harsh conditions of heat and vibration may be generated during these operations which
could cause damage to the units.
In particular, it is essential to follow the appropriate precautions when disconnecting or removing the airbag DCU.
Supplementary Restraint System Precautions
Any work undertaken which involves the removal or replacement of any item of the Supplementary Restraint System
(SRS), requires extreme caution and the appropriate precautions must be followed.
+ GENERAL INFORMATION, Supplementary Restraint System Precautions.
Equipment
Prior to commencing any test procedure on the vehicle, ensure that the relevant test equipment is working correctly
and any harness or connectors are in good condition. This particularly applies to electronic control units.
