Hi NISSAN PRIMERA P12 2002 D SVE 18 MARCH 2024
Hello, Malcolm. It seems like you are facing an issue with the alarm system of your Nissan Primera P12 from 2002. Based on the symptoms you've described, it does sound like there might be a fault with the alarm system or the central locking mechanism.
Given that you have already tried a few troubleshooting steps such as disconnecting the battery and replacing the micro switches, it might be a good idea to further investigate the alarm system itself. Since the hazard lights are flashing without any audible alarm sound and the central locking is behaving inconsistently, there could be a fault in the alarm control unit or wiring.
One possible cause could be a faulty alarm module or a loose connection in the wiring harness related to the alarm system. It's also worth checking the condition of the alarm siren to ensure it is functioning properly.
Considering that the issue seems to have improved after disconnecting and reconnecting the battery, it's possible that there is an intermittent fault related to the power supply or a reset of the alarm system.
If the problem persists, it might be best to consult with a professional mechanic or an auto electrician who can perform a more in-depth diagnostic test on the alarm system to pinpoint the exact cause of the issue.
In the meantime, if you experience the hazard lights flashing again, try to document when and under what circumstances it occurs. This information can be helpful in diagnosing the problem more accurately.
I hope this information helps, and I wish you the best of luck in resolving the issue with your Nissan Primera P12. Feel free to reach out if you need further assistance or have any more questions.
Where is the inertia switch on a nissan maxima 2000
There isn't one. Easiest way to diagnose the fuel system is at the fuel pump relay. Make sure there is a good 12v supply and solid ground at the relay. Insert a jumper wire across the load side of the relay which would provide the pump a constant 12v supply. If it doesn't run, it's time to drop down the tank and see if you have 12v to the pump. If so, it's probably time for a new pump

You will probably have to reset the ECU as it thinks the vehicle may be stolen and shuts the fuel supply off.
I always plug a motorbike battery with a cigar lighter plug on it, to keep the electronics live whist changing the battery.
It keeps 12volts on the system and avoids this sort of thing from happening.
2006 Nissan Xterra Security Issue
Is the security light lit up on the dash at all?What happens if you try to start the vehicle without unlocking the driver door with the key?Lastly, have you ever replaced the battery on your key fob? When their batteries get low, they can cause various problems that resemble mechanical faults or security problems.

Check the dimmer switch to ensure it's not turned down. If the dimmer is fine, check the fuse for the dashboard lights. If the fuse is blown, replace it. If the issue persists, it may require professional diagnosis for a potential electrical problem or a malfunctioning instrument cluster.
Why is my 02 nissan xterra supercharger 3.3 v6 is not running any better after I change crankshaft position sensor
The crankshaft position sensor's function is to let the PCM know the crankshaft's position, so fuel, spark timing etc can be fine tuned, based on engine load and driving conditions.
Some vehicles cannot start with a faulty or failed CPS, while others can but will have poor drivability.
Did you change your CPS because it was confirmed to be faulty or did you change it to improve the engine's running conditions? Did you pull any OBDII codes that pointed to the CPS circuit, before replacing it?
Chance are the CPS wasn't the cause of the issues you had.
Nissan Altima. P1574 ASCD speed sensor A.
In a Nissan Altima, code P1574 typically indicates an issue with the ASCD (Automatic Speed Control Device) speed sensor A. This sensor is responsible for detecting the vehicle's speed and providing the necessary information for the ASCD system to function properly.
When this code appears, it usually means that there is a problem with the speed sensor itself, the wiring connected to it, or possibly a malfunction in the ASCD control unit. It can lead to issues such as the cruise control not working, the vehicle not maintaining a set speed, or other related problems.
To diagnose and fix this issue, you may need to perform the following steps:
1. Check the wiring and connections: Inspect the wiring harness connected to the ASCD speed sensor A for any signs of damage, corrosion, or loose connections. Make sure all connections are secure and free of debris.
2. Test the sensor: The ASCD speed sensor A itself may be faulty and need to be tested. You can use a multimeter to check the sensor's resistance and compare it to the manufacturer's specifications.
3. Check the ASCD control unit: If the sensor and wiring appear to be in good condition, the issue may lie with the ASCD control unit. Testing and potentially replacing this unit might be necessary.
4. Clear the trouble code: Once you've identified and resolved the underlying issue, you can clear the trouble code from the vehicle's system using an OBD-II scanner. This will reset the system and allow you to see if the problem persists.
If you are not comfortable performing these steps yourself, it's recommended to consult with a qualified mechanic or dealership with experience in diagnosing and repairing ASCD-related issues in Nissan vehicles. They can provide a more accurate diagnosis and solution to ensure your Nissan Altima's ASCD system operates correctly.
