Notes on replacement of safety-relevant and special components - AH00.19-P-1000-08A
Yellow, orange or red plugs and couplings are intended for the supplemental restraint systems (SRS), roll bar and high-voltage components.
Work on high-voltage components or on hybrid components may only
be conducted by trained workshop personnel. All high-voltage lines fitted in the vehicle are marked with the warning color orange. If the chafe protection at the high-voltage lines is damaged or the lines are damaged due to external influences (e.g. bitten by animals), the lines must be replaced immediately. Repair is not
permissible.
Always observe the following when repairing couplings for squibs (supplemental restraint system (SRS)):
The repair area must be between 100 mm and 1000 mm behind the squib. Cables which have already been repaired are provided with a yellow marking. For repair lines without color coding, this is to be subsequently applied.
Carry out the first repair as close to the plug as possible. In the case of subsequent repairs the old soldered connectors should be removed and the new ones should be attached behind them, the wiring harness should be replaced if necessary.
Before cutting through the lines it is absolutely essential to assign the lines to the corresponding pins in accordance with the wiring diagram. Do not mix up the pin assignment.
The line colors of the repair kit may deviate from the original fitting
Screened lines and light plastic-sheathed cable must never be repaired
In general the following applies to cable repair:
If more than ten lines per branch-off line are damaged, the wiring harness module must be replaced.
