P1700 is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

On many Nissan models the ECM and TCM communicate this over the CAN network. When P1700 is present the driver may notice a transmission warning light, harsh or de...
