Self-diagnosis of automatic transmission on Nissan Cefiro
Note: These instructions are for Nissan Cefiro vehicles manufactured before 2004. Newer models may require different procedures.
Materials:
* Paperclip or wire
* Rag or paper
Instructions:
1. Warm up the engine: Start the engine and let it idle for a few minutes until it reaches operating temperature.
2. Turn off the engine: Turn off the engine and remove the key from the ignition.
3. Locate the diagnostic connector: The diagnostic connector is usually located under the dashboard on the driver’s side. It can be closed with a panel or a lid.
4. Connect the paperclip: Straighten the paperclip and insert one end (approximately 1 cm) into the diagnostic socket. The other end should touch the DLC (Data Link Connector) pin.
5. Insert the key into the ignition: Do not turn the key.
6. Observe the Check Engine Light Flashing: The Check Engine Light will begin flashing trouble codes.
7. Count the blinks: Record the number of blinks for each code. The codes consist of two separate flashing sequences:
* Short flashes: Indicates the first digit of the code.
* Long flashes: Indicates the second digit of the code.
8. Read all codes: Repeat steps 4-6 until all codes have been read.
Example:
* 5 short flashes then 2 long flashes = Code 52
* 3 short flashes then 1 long flash = Code 31
Reset codes:
Once the fault codes have been read, they can be reset as follows:
1. Remove the paper clip from the diagnostic connector.
2. Start the engine.
3. Let the engine idle for several minutes.
4. Turn off the engine.
Decoding codes:
Fault codes for Nissan Cefiro automatic transmission can be found in the vehicle repair manual or on various websites.
Notes:
*If the Check Engine Light flashes quickly and continuously, it indicates a serious problem and requires immediate attention.
*If no codes are displayed when the Check Engine light is flashing, there may be no codes stored in the trouble memory.
* For more accurate diagnosis and repair, it is recommended to contact a qualified specialist.
