Volvo C70 Model Year 2007 Full Details
New C70
• The new C70 is a new coupé/convertible that replaces the previous C70 models
• The C70 has a new design, the car is based on the S40/V50 and at the same time has many of the characteristics and functions found in these cars.
• The C70 has a lot of new technology but much of the technology is in principle the same as in the S40/V50.
The launch
• The C70 was exhibited at the motor show in Frankfurt (Germany) at the start of September 2005.
The date when the cars are available for the customer varies depending on market. For precise information on dates, contact your own sales department.

Compared with the old C70 the new C70 is shorter, wider and lower. The interior of the car is slightly lower in terms of height, the front section of the interior is slightly narrower, and the rear section is wider
Electrical system, design
Network
The network in the C70 is based on the same principle as the S40/V50:
• CAN-HS (High Speed), 500 kbps
• CAN-LS (Low Speed), 125 kbps
• MOST (Media Oriented System Transport), audio system 24.8 Mbps
• LIN (Local Interconnect Network), serial communication 9.6 kbps
To prevent electrical interference in the CAN network there are termination resistors that bridge over CAN HS and CAN LS. One in each endpoint on both the high and low speed side of the network. Each termination resistor has a resistance of 120 Ω.
For CAN HS there are termination resistors located in the Steering Wheel Module (SWM) and in the Engine Control Module (ECM). For CAN LS there are termination resistors located in the Driver Information Module (DIM) and in the Supplemental Restraint System Module (SRS).
Both termination resistors create a parallel circuit. If the CAN network is complete then the resistance in each side of the network is approx. 60 Ω.
