C3648 Nissan Bassara OBD Code

OBD/2 C3648 error code description and symptoms.

The Transmission Fluid Pressure Switch allows the engine's control module (PCM) or Transmission Control Module (TCM) to use hydraulic fluid to engage the clutches in the transmission to allow for smoother shifting while driving. If the PCM or TCM detects an issue with the hydraulic clutch or the pressure switch, the PCM or TCM will set code C3648

At this point we are assuming that the fuses and relays are good. You will need to locate the PCM/TCM and the power input signal circuit using your vehicle information source. Unplug the connector from the PCM/TCM, place the ignition switch in the ON position, and probe the appropriate circuit with the positive test lead of the DVOM.

C3648 Nissan Bassara Error Code Repair Process :

If your vehicle failed a C3648 test and the C3648 Check Engine Light is NOT on, chances are you have a problem with the OBDII system, a burned out MIL lamp, or a faulty catalytic converter. The converter is essentially an afterburner that cleans up the exhaust after it exits the engine. The OBDII system uses two speed rear axle input switch circuit short to vbatt a ownstream oxygen sensor to monitor the efficiency of the converter, and it should detect a drop in converter efficiency if the converter has been contaminated or is failing (ignition misfiring, leaky exhaust valves, and oil burning can all damage the converter). What you want to look two speed rear axle input switch circuit short to vbatt: Any conditions that might cause ignition misfire, an overly rich or lean fuel condition, or loss of compression. Use your OBD Express DIY to look at the oxygen sensor outputs, coolant temperature, airflow, calculated engine load, and inlet air temperature.

Common Causes of Nissan Bassara C3648 OBD2 Code

A common cause of code C3648 is the failure of Two Speed Rear Axle Input Switch Circuit Short to Vbatt, but there are several other possible causes as well, such as ;

Continuous oil flow to the VCT piston chamber
1Camshaft Position Sensor circuit poor electrical connection
Intake Valve Timing Control Solenoid Valve harness is open or shorted
Faulty variable valve timing (VVT)

C3648 is a kind of Chassis Trouble Code

Diagnosing chassis noises can be one of the most frustrating problems technicians face. Fortunately, manufacturers have engineered noise, vibration and harshness (NVH) diagnostic techniques and equipment to find the source of the noise.
