Grounding points
| Grounding points |
There are two main types of grounding point in the car; those having a component number and those where a component is grounded directly to the chassis, such as temperature sensors, oil pressure sensor, etc.
The car battery is connected to ground by means of two cables. One has a cross-section area of 25 mm 2 and goes straight to the gearbox (grounding point G25).
The other has a cross-section area of 16 mm 2 and goes to grounding point G2, which is located behind the battery on the left-hand wheel housing.
A redundant ground consisting of a 10 mm 2 cable runs between the gearbox and the left-hand wheel housing. It is shown on the service diagrams as a lead between G2 and G25.
Grounding points having a component number are covered in this section.
A component can be connected to different grounding points depending on whether the car is left or right-hand drive. This is indicated in the relevant system diagram.
Many cables can be gathered together in a crimp connector just before a grounding point. This is indicated in the relevant grounding point list.
