C1e91-97 Side Radar Malfunction

Dtc Description

DTC Description

DTC DETECTION LOGIC

DTC No.	CONSULT screen terms (Trouble diagnosis content)	DTC detection condition
C1E91–97	Side radar malfunction (Side radar malfunction)	Diagnosis condition	When Ignition switch is ON.
		Signal (terminal)	–
		Threshold	Side radar is blocked
		Diagnosis delay time	–

Note:

DTC “C1E91–97” may be detected under the following conditions except for possible cause. (Explain to the customer about the difference between the contamination detection function and the indication when the malfunction is detected and tell them “This is not malfunction”.)

The side radar may be blocked by temporary ambient conditions such as splashing water, mist or fog.
The blocked condition may also be caused by objects such as ice, frost or dirt obstructing the side radar.
Due to the nature of radar technology it is possible to get a blockage warning and not actually be blocked. This is rare and is known as a false blockage warning. A false blocked condition either self-clears or clears after an ignition cycle.

POSSIBLE CAUSE

Stain or foreign materials is deposited.

U007b-00 Can Comm Circuit

Dtc Description

DTC Description

CAN COMMUNICATION

CAN (Controller Area Network) is a serial communication line for real time applications. It is an on-Nissan Sentra vehicle multiplex communication line with high data communication speed and excellent error detection ability. Modern Nissan Sentra vehicle is equipped with many electronic control units, and each control unit shares information and links with other control units during operation (not independent). In CAN communication, control units are connected with 2 communication lines (CAN-H, CAN-L) allowing a high rate of information transmission with less wiring. Each control unit transmits/receives data but selectively reads the required data only.
