Technical Background
The missing insulation allows water to get to the electronic components in the shock absorber, causing corrosion.
As a result the function is restricted.
Production Solution
Not applicable.
Service
1.
Replace the affected shock absorber according to the repair manual.
2.
When fitting the shock absorber make sure the electric cable is routed correctly. The connector with the
labelling must point forward (Figure 2). The cable must also not be twisted or under tension to prevent any
damage to the wires in the cable and to the outer insulation (Figure 3). It is recommended to hang cable
and connector freely on the absorber first, then secure it.
Figure 2. Correct connector alignment and cable routing.
