2006 Cayenne not starting

[thor1974]

hi,

 

i have a 2006 cayenne the car dont start. the only trouble code what i have is P1517 Main circuit. i dont get 12 V to the Pumps only if i jump the Relay. the Relays are new.

what could cause that problem?

 

please help

P1517 Throttle Adjusting Unit: Abortion of Test due to Negative Influence on Ambient Condition - Above Limit

 

Note:  This fault is only recorded if the adaptation was not performed correctly after the throttle adjusting unit or DME control module was replaced.

 

Possible cause of fault
- No adaptation performed

 

The following conditions must be satisfied to ensure that the adaptation is performed:
- Do not actuate the accelerator pedal (for instance, make sure that there is not a carpet pressing on the pedal)
- Vehicle is stationary
- Battery voltage between 10 V and 16 V
- Engine temperature between 5 °C and 100 °C
- Intake air temperature > 10°C

1. Switch the ignition on without starting the engine
2. Using the 9588 Porsche System Tester ll perform a "throttle adaptation" under the "System adaptation" section (the notes above must be observed)

and that is the reason why i have 0Volt on the Fuel  pumps?

I don't know for sure I have never measured that.

If that P1517 is your fault code then there is only one solution given in the service manual - "perform adaption".

i try to start the engine and get more faults

 

P1517 Main relay circuit

P2138 Throttle/pedal position sensor/switch D / E voltage correlation

P2122 Throttle/pedal position sensor/switch D circuit low input

P2127 Throttle/pedal position sensor/switch E circuit low input

 

i have right now no idea what that means
