Vehicle: 2013 Nissan Versa Sedan, L4-1.6L
Mileage: 68,452
Problem: The vehicle came in to the shop because the engine would continue to run 4-5 seconds after pressing the Start/Stop button; it used to shut off right away.
Details: The Tech-Assist consultant advised the technician to monitor voltage on ignition-related fuses with the ignition off to see if there was any feedback voltage from a component.
The technician found many ignition fuses in the Intelligent Power Distribution Module (IDPM) remained at 6-7 volts for a few seconds after the Stop button was pushed. Next, he was advised to pulled fuses one at a time until the voltage dropped to 0-volts at the exact moment the Stop button was pushed.
Feedback voltage was coming through fuse #54 in the IPDM. It was feeding voltage to other fuses on the same circuit (see wiring diagram).
The tech traced the circuit on fuse #54 to find that it went through the E21/B12 connector in the driver’s footwell. He found that the connector was very corroded, and the pins were shorting together (See Image).
Confirmed Repair: The tech replaced the pins and both connectors and that resolved the problem. Fixed!
