Sounds as if you may have failed to reconnect some wiring. If not, security system may need to be re-set. I don't know how to do that on your car, sorry. Are you absolutely sure you have a good battery connection? Clean all cables to battery and retry.

Where do I find the 2008 Buick Enclave neutral safety switch


It's called a Manual Shift Detent (w/Shaft Position Switch) Lever Assembly. And it's inside the transmission .
What problem are you having ? No crank , when you turn the ignition switch to the start position nothing happens ? No click ,nothing ? If your think of just replacing the switch ,stop , did you have it diagnosed ? This starting system is computer controlled .
When the ignition switch is placed in the Start position, a discrete signal is supplied to the body control module (BCM) notifying it that the ignition is in the Start position. The BCM then sends a message to the engine control module (ECM) notifying it that CRANK has been requested. The ECM verifies that the transmission is in Park or Neutral. If it is, the ECM then supplies 12 volts to the control circuit of the crank relay. When this occurs, battery positive voltage is supplied through the switch side of the crank relay to the S terminal of the starter solenoid.

have the vehicle checked .

I have a hyundai tiburon with a 2010 engine and a 2007 transmission when i presson the accelerator the transmission makes the loud noise I had the computer scanned and it has a code of p1529.


code p 1529 refers to transmission control module (TCM)--communication ( communication is the word)===causes-- wiring---TCM---ECM
because you have a different transmission to what was originally fitted , the TCM may have different presets and there is a conflict being caused in the ECM
I might suggest as a start that you get a known good TCM for the 2010 box and see if that removes the problem
when you press the accelerator there is an actuator that cuts in to change ratios and that change has to be compatible to the settings in the TCM

Why do my dome lights not come on when door is open?


The dome light is on a separate fuse since the dome light is one of the few lights that are connected to the battery even if the key is off.

There are usually two relay/fuse boxes

One under the hood on the drivers side near the firewall.
The other place is under the dash to the left of the drivers knee.
Hope this helps.

Nissan altima p0725


HERE IS THE ANSWER.
P0725 - Nissan Type Powertrain - Transmission - ISO/SAE Controlled Description Engine speed (RPM) - incorrect voltage signal ECM to TCM
Cause Wiring, RPM sensor, TCM, ECM
P0720 - Nissan Type Powertrain - Transmission - ISO/SAE Controlled Description AT - vehicle speed sensor (VSS)
Cause Wiring, VSS, TCM
P0710 - Nissan Type Powertrain - Transmission - ISO/SAE Controlled Description Transmission fluid temperature sensor - excessively high or low voltage
Cause Wiring, temperature sensor, TCM, ECM
P0826 - Generic Type Powertrain - Transmission - ISO/SAE Controlled Description Up and Down Shift Switch Circuit

the dtcs of your car are so many, my best suggest is go to garage for repair. or if you would like to repair by yourself, you need to buy a diagnostic tool such as multidiag j2534

ABS light comes on when stopped and restarted hot


Whenever this warning light or any other stays on in the dash it is indicating that the systems control module (or the system sensor in the case of lights like low oil pressure, door open indicators etc.) has detected a fault, it then disables the system (this applies to ABS,TCS, TCM, SRS, TPMS and BCM faults and others) as long as the light is on. You must now have the dealer hook up a special electronic diagnostic tool and "scan" the system for the fault code that is stored for the problem(s)

Legend of Abbreviations. ABS Anti-lock brake system. TCS Traction control system, TCM Transmission control module, SRS Supplemental restraint system, BCM Body control module. TPMS Tire Pressure Monitor System

I have a mitsubishi montero 1999 and the code is p1720


The Engine Control Module (ECM) receives two vehicle speed sensor signals via the Control Area Network (CAN) communication line. One is sent from Vehicle Dynamic Control (VDC) / Traction Control System (TCS) / Anti-Lock Brake System (ABS) control unit, and the other is from Transmission Control Module (TCM). ECMuses these two signals for engine control. Possible Causes: - VDC/TCS/ABS to ECM circuit harness is open or shorted
- TCM to ECM circuit harness is open or shorted
- VDC/TCS/ABS to ECM circuit connectors
- TCM to ECM circuit connectors
- Faulty revolution sensor

I have a 2003 saturn Ion 2 and my car's engine light came on the other day and shortly after the car lost power when I was driving, it still was able to move but it was as though it was stuck in first and...


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.
Circuit Description
The engine coolant temperature (ECT) sensor is a variable resistor, that measures the temperature of the engine coolant. The ECT sensor has a signal circuit and a low reference circuit. The engine control module (ECM) supplies 5 volts to the ECT signal circuit, and a ground for the ECT low reference circuit. When the ECT is cold, the sensor resistance is high. When the ECT increases, the sensor resistance decreases. With high sensor resistance, the ECM detects a high voltage on the ECT signal circuit. With lower sensor resistance, the ECM detects a lower voltage on the ECT signal circuit. If the ECM detects an excessively high ECT signal voltage, which is a low temperature indication, DTC P0118 sets.

Diagnostic Aids
• If a short to a separate 5-volt source occurs this DTC may set.
• Use the Temperature vs Resistance table to test the ECT sensor at various temperature levels to evaluate the possibility of a skewed sensor. A skewed sensor could result in poor driveability concerns

Sounds like you need a new coolant temp. sensor , but test it ! Videos on youtube showing how to do it .
Circuit Description
To improve shift feel, the transmission control module (TCM) may request that the engine control module (ECM) reduce engine torque during shift events. When such a request is received, the ECM responds by retarding the base ignition timing and notifying the TCM that the request has succeeded. If the ECM is unable to comply with the request, the ECM sends the TCM a message that the request has failed.
The torque reduction request is sent to the ECM through a communication network called the controller area network (CAN). Two circuits are used to communicate CAN data between the ECM and TCM. A fault in the CAN will not cause DTC P1781 to set by itself. If a CAN fault occurs, other DTCs will set before DTC P1781.
When the TCM receives a torque reduction failure message from the ECM, then DTC P1781 will set. DTC P1781 is a type A DTC.
