SOURCE: My 2004 Saturn ion 3 has 2 codes coming up u2105 p0700 an it won't go in drive or reverse what could it be

First off you need to understand your vehicle has several control modules on board . The PCM - engine computer , TCM - transmission control module , SRS - air bag module , Anti theft , antilock brakes , An these modules all are able to talk to each other on a communication network , On your vehicle it happens to be the CAN data bus !
The transmission control module (TCM) uses the controller area network (CAN) to signal the engine control module (ECM) that the TCM is requesting malfunction indicator lamp (MIL) illumination. This happens when the TCM has determined that a failure that affects emissions has occurred in the transmission control system. When the ECM receives the correct message from the TCM, DTC P0700 will set.
Which transmission does your vehicle have ?
Automatic Transaxle AF23-5
OR
Automatic Transmission VT25-E
DTC U2105-U2199
The controller area network (CAN) serial data line is a high speed serial data bus used to communicate information between the engine control module (ECM), body control module (BCM), and the transmission control module (TCM). Typical data-transmission speeds must be high enough to ensure the required real-time response is maintained. The CAN serial data line does not communicate with the scan tool via the data link connector (DLC). CAN serial data information is interpreted by the BCM and transmitted to the serial data line by the BCM.
I suggest you take this to GM dealer or some other ASE certified repair shop .

1.9 dti opel pick up wont start


It could be an Immobilizer fault, if the spanner /car light comes on.
If you have a spare key, try it
A Flashing spanner light normally means immobiliser fault hence the non-start. The spanner light left might just be an indication that it has stored the "wrong transponder" code.
Opel will have to clear this but you might need a CIM as well that is the bit that reads the key to allow it to start.
Try the spare key if you have one

On 1.7 DTi models, a defective solenoid in the pump can cause failure of the ECU due to excessive current draw causing components to burn out. but this *should* cause other fault codes to appear.

Car wont start for a few minutes, then starts and runs fine.


Try using an OBD II diagnostics tester to see if there's a fault code stored in your pcm, if you don't have one you can purchase one at most auto parts store's, some auto parts stores will do this test for you at no cost, one for example is auto zone, this should tell you what the problem might be. Good luck.
