B2413 , B2414

Recirculation flap motor, no continuity or short circuit



Conditions

B2413: Control module output pin 2 or 21, open circuit. B2414: Control module output pin 2 or 21, short circuit.

Diagnostic procedure:


1. Unplug the recirculation motor's 2-pin connector. Plug the ISAT into the data link connector and issue the command "RECIRC.FLAP MOTOR" in the "ACTIVATE" menu. Read the voltage present at the connector as follows:

• Press "ON" on the ISAT and take a reading across pin 2 of the connector and ground.

• Press "OFF" and take a reading across pin 1 of the connector and ground.

In both cases the reading should be about 12 V. If it is, change the recirculation motor.

2. Check the wiring for continuity/shorting as follows:


• across pin 21 of the ACC control module and pin 2 of the recirculation motor's connector.

• across pin 2 of the ACC control module and pin 1 of the recirculation motor's connector. Locate and rectify the open circuit/short circuit.

3. Go to section for further measures.
