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
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
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

Confirmed Repair: The tech replaced the
pins and both connectors and that resolved the
