EVIC Signals Danger Ice With Elevated External Temperature

WARNING: This page is about a different car, the 2020 Jeep Renegade. However, it is still accessible from the selected car via links, so may be relevant.

The Instrument Panel Cluster receives external temperature information from the Body Control Module (BCM), which in turn receives the value from the ambient temperature sensor in the passenger side outside mirror.

0	PRELIMINARY CHECKS	Result OK	Result Not OK	Action
	Check that the temperature shown on the instrument panel cluster display is plausible. Also check if by power cycling the instrument panel cluster the temperature returns plausible	Continue to Step 3	1. Implausible value error 2. The value returned correctly with the new key cycle	1. Continue to Step 1 2. Continue to Step 3
1	CHECK WITH ACTIVE DIAGNOSIS	Result OK	Result Not OK	Action
	Connect the diagnostic scan tool to read data from the BCM. With the diagnostic tool test environment in active diagnosis, activate the self-test function for the instrument panel cluster	Continue to Step 2	The function in question is not changed by active diagnosis	Replace the instrument panel cluster
2	CHECK FOR ERRORS	Result OK	Result Not OK	Action
	With the diagnostic scan tool still connected to the DLC, go to the environment BCM and verify the absence of any error on the ambient temperature sensor	Continue to Step 3	1. Ambient temperature sensor defective / incorrectly calibrated 2. Faulty wiring	1. Replace the ambient temperature sensor 2. Restore the correct wiring NOTE: The ambient temperature sensor is an integral part of the passenger outside mirror and is replaced with the mirror.
3	VERIFY PROPER OPERATION	Result OK	Result Not OK	Action
	Verify that the fault is no longer present	Diagnostic complete	The anomaly persists	Contact Technical Support for more information on the problem
