6.4.3 Removing and installing high-voltage
wiring harness for hybrid battery - PX1-
The high-voltage wiring harness for hybrid battery - PX1- consists
of the following wires:
♦ High-voltage wire for hybrid battery, positive terminal - P1- (red
coloured ring)
♦ High-voltage wire for hybrid battery, negative terminal - P2-
(brown coloured ring)
WARNING
Working on vehicles with high-voltage wiring:
• Do not support yourself or tools on high-voltage wiring or
associated components --> this can damage the insula‐
tion.
• High-voltage wiring must not be excessively bent or
kinked --> this can damage the insulation.
• The round high-voltage connectors are colour-coded with
an external coloured ring and are provided with mechan‐
ical coding or guide lugs. It is important to observe this
coding when joining up the round high-voltage connec‐
tors, otherwise the connectors can be damaged.
