Wubster100 Posted February 22 Report Share Posted February 22 Remove the IPMA cover by pulling down on it, starting from the front of the vehicle. Do you see the IPMB heating element wiring? 1 Quote Link to comment Share on other sites More sharing options...
Iroga Posted February 23 Author Report Share Posted February 23 (edited) Yes of course, I checked it. Resistance is less than 1 ohm on the wires. The heating grid has resistance. There are no errors in IMPA and BCM. Edited February 23 by Iroga 1 Quote Link to comment Share on other sites More sharing options...
Wubster100 Posted February 23 Report Share Posted February 23 The IPMA supplies voltage and ground to the camera windshield defrost heater. The IPMA uses input from the front camera and the ambient air temperature data from the PCM to command the heater on and off. The heater may be commanded on if the ambient temperature is below 5°C (41°F) 1 Quote Link to comment Share on other sites More sharing options...
Wubster100 Posted February 23 Report Share Posted February 23 (edited) B120C:11 Heater for Windshield Mounted Sensor: Circuit Short To Ground An on-demand and continuous memory DTC that sets in the IPMA if an excessive current draw is detected on the heater output circuit. B120C:13 Heater for Windshield Mounted Sensor: Circuit Open An on-demand and continuous memory DTC that sets in the IPMA if a lower than expected current draw is detected on the heater output circuit. U1000:11 Solid State Driver Protection Activated: Circuit Short To Ground A continuous memory DTC that set in the IPMA when the IPMA has temporarily disabled the camera windshield heater defroster output because an excessive current draw exists (such as a short to ground). The IPMA cannot enable the output driver until the short is corrected. ADDRESS all other IPMA Diagnostic Trouble Codes (DTCs) first. After the cause of the concern is corrected, CLEAR the Diagnostic Trouble Codes (DTCs) and REPEAT the IPMA self-test to enable the output driver Edited February 23 by Wubster100 1 Quote Link to comment Share on other sites More sharing options...
Wubster100 Posted February 23 Report Share Posted February 23 (edited) IPMA Camera Windshield Defrost Heater The camera windshield defrost heater keeps the windshield in front of the IPMA clear of frost and ice. The IPMA uses input from the front camera and the ambient air temperature to turn the camera windshield defrost heater on and off. Voltage and ground is supplied to the heater by the IPMA. The heater may be commanded on if the ambient temperature is below 5°C (41°F ). The IPMA camera windshield defrost heating element is integral to the windshield and can not be serviced without replacing the windshield. Before replacing the IPMA camera heated windshield element or the IPMA for an IPMA camera heated windshield element concern, verify the integrity of the wiring, connectors and terminals on the jumper harness. Camera Windshield Defrost Heater The camera windshield defrost heater is a resistive-type heater grid that is adhered to the inside of the windshield directly in front of the IPMA camera. The camera windshield defrost heater uses a jumper harness between the component and the vehicle harness. Before replacing the camera windshield defrost heater or IPMA for a camera windshield defrost heater concern, verify the integrity of the wiring, connectors and terminals on the jumper harness.

Wubster100 Posted Wednesday at 01:48 AM Report Share Posted Wednesday at 01:48 AM I tried to look for an IPMA self test on the latest version, 2.4.17 beta, but I was unable to find it. However, there was an IPMB self test. To test, I unplugged my camera heating element. I tried some other module self tests, but they did not affect the IPMA heater. I still did not get any DTCs despite my camera heating element being unplugged. I suppose that to get a DTC, the vehicle probably has to attempt to power on the heating element so that it realizes there is a fault. It is not cold enough for the heater to turn on.

johnmarkp Posted Wednesday at 02:03 PM Report Share Posted Wednesday at 02:03 PM Maybe you could try holding some ice cubes over the camera area of the windshield. Or just block it with a post it note. I am not sure what causes the heater to be activated, but blocking the camera is a good start.

Wubster100 Posted 4 hours ago Report Share Posted 4 hours ago 1 hour ago, Iroga said: I will try tomorrow when the temperature is zero. Unplug this connector so that the heater is disconnected from the IPMA. Then, carry out the IPMA module reboot. Finally, carry out the IPMA self test. You should get DTC B120C. The IPMA should detect that the heater circuit is open because the heater is unplugged. If the IPMA does not detect that the heater is unplugged, then there could be a short circuit or something else that is causing the IPMA to think that the heater circuit is still ok.
