C12009
Diagnostic information CAN
Communication with control unit not possible
NOTE: Internal function test completed.
Diagnostic conditions
The PAS control unit initially tests internal function sequences after wakeup. If they are OK, all diagnosable outputs are then
tested and any faults are stored.
Wakeup of the control unit by:
Eventcontrolled CAN message
Key contact (terminal S)
Ignition ON
Possible fault causes
No power supply of the control unit
Incorrect coding of the control unit
Short circuit or open circuit in the CAN network
Control unit faulty (in most cases, faulty coding is the cause and not the control unit)
Fault effects
Communication no longer possible via the CAN bus
The control unit is no longer addressable for all other control units

Porsche Cayenne S
2009-2008
------------------------------
Porsche Cayenne S
Red Painted Brake Calipers, Silver Painted Brake Calipers
2006-2003
---------------------------
Porsche's sport utility gets a revised appearance and some enhanced technical features for 2008. The Cayenne has a more aggressive outward appearance for 2008, with a front air dam, widened bumpers, and new headlight style in front, plus broader, more defined wheel arches.
Direct injection is fitted to all three engines, increasing real-world fuel economy and increasing performance, and a newly available Porsche Dynamic Chassis Control (PDCC) helps improve handling while also increasing ride comfort.
All Cayenne models get a button-engaged Sport mode that changes engine response. There's also a new rollover sensor linked to the curtain air bag system and seatbelt pretensioners. Dynamic Curve Lights are newly available across the line and standard on the Turbo, and Porsche Stability Management now includes trailer stability control and an off-road anti-lock mode. Standard features and options have been thoroughly revised; a power liftgate is now standard, and 21-inch wheels are newly available.
Porsche Cayenne S Front disc brake pads installation 03-09
The 2008 Porsche Cayenne is offered in three different models--the base V6, the S, and the Turbo--each offered with a different powertrain. A 290-horsepower, 3.6L V6 comes with the base model, while the S comes with a 385-horsepower, 4.8L V8. The top-of-the-range Turbo adds an especially powerful 4.8L turbocharged V8 that makes 500 horsepower and 516 lb-ft of torque. A six-speed automatic transmission, with Tiptronic manual control, is standard across the line.
The Turbo can accelerate from zero to 60 mph in only 4.9 seconds and reach a top speed of 171 mph.
All three engines now have direct injection for improvements in both fuel efficiency and power. Both V8 models adopt VarioCam Plus variable valve timing, which varies intake valve timing and lift, and a new variable oil pump for the dry-sump lubrication system that's oriented toward high-performance driving.
The five-passenger Cayenne offers two spacious rows of seating; the rear seat is split 60/40 and can fold flat to expand the cargo floor for larger items.
A newly available system called Porsche Dynamic Chassis Control (PDDC) uses hydraulic pressure to change the stabilizer-bar response depending on the road surface or cornering forces. The system allows both an improved, smoother ride when on- or off-road along with improved handling.
All Cayenne models get large disc brakes with six-piston calipers in front and four-piston ones in back. The Porsche Stability Management system--including a new trailer stability control mode--is also standard across the line. Front side air bags and full-length side curtain air bags are included as well.
The options list for the Cayenne is vast, including everything from an off-road package with skid plates to a trailer-towing package and luxury features such as a heated steering wheel and various distinctive woodgrain interior trims. Base V6 models get 17-inch alloy wheels, while S models upgrade to larger 18-inch wheels. Several different wheel designs are optional, ranging up to flashy 21-inchers
Brake Pad: Testing and Inspection
Check thickness of the disc brake pads
NOTICE:
Installation of brake pads with the wrong brake pad quality
- Longer braking distance
- More wear on brake pads
-> Only use the type-specific brake pads listed in the Porsche Parts Catalogue.
Replace the brake pads when the brake pad wear indicator light comes on,
but no later than when there is a residual pad thickness of 2 mm on each axle.
-> Replace the brake discs on each axle as soon as the brake pad wear limit is reached.
Information
- If brake pad wear is indicated by the warning light, the warning contact (sender including wire and plug connection) must also be replaced.
- Replacement of the warning contact can be avoided by replacing the brake pads no later than when the pad thickness is 2.5 mm -arrows-.
- NOTICE: contacts must be replaced if the core of the line is worn.
- However, if only the plastic part of the warning contact is worn, there is no need to replace it.
NOTICE
Removing/fitting wheels
- Risk of damage to (ceramic) brake discs
-> Use two assembly pins when removing and fitting the wheel.
-> Carefully guide the wheel towards the wheel hub, thereby preventing any heavy impact on the (ceramic) brake disc.
1. To check the brake pads, remove the wheels during the maintenance. Before removal/installation of wheel, screw the assembly aids (assembly pins) -see figure- , instead of two wheel bolts, into the wheel hub. During removal, first remove the three remaining wheel bolts and remove
the wheel carefully without touching the brake discs.
2. Visually inspect the brake pads for wear.
