With a live data tool:
: Verify the actuator plug is receiving proper voltage (typically 2-3 volts for signaling). Solutions and Permanent Fixes
Once you've confirmed the problem, there are several paths to a solution, ranging from simple fixes to component replacement. In plain English: The engine control unit (DME)
Check both the and lower (bumper) shutters for visible debris like sticks or rocks.
, which sometimes allow for a software recalibration to fix "plausibility" errors without replacing hardware. Debris Removal:
When he arrived, the mechanic took a look at the car and told John that the error code "32ce00" indicated a problem with the car's ignition system. Specifically, it seemed that the ignition coil was malfunctioning. Start/Stop Issues: | Repair Option | Estimated Cost
