 The side radar may be blocked by temporary ambient c onditions 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.

DTC DETECTION LOGIC
NOTE:
DTC “C1B55” may be detected under the following conditions except for possible cause. (Explain to the customer about the differ
ence
between the contamination detection function and the indication when the malfunction is detected and tell them “This is not mal func-
tion”.)
 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 i s known as
a false blockage warning. A false blocked condition either self-clears or clears after an ignition cycle.
Diagnosis ProcedureINFOID:0000000006223904
1.CHECK THE REAR BUMPER
Check rear bumper near the side radar contaminated with foreign materials.
>> GO TO 2.
2.CHECK THE SIDE RADAR
Check side radar and the side radar outskirts contaminated with foreign materials.
>> GO TO 3.
3.CHECK THE SIDE RADAR INSTALL CONDITION
Check side radar installation condition (installati on position, properly tightened, a bent bracket).
>> GO TO 4.
4.INTERVIEW
1. Ask if there is stain or foreign materials.
2. Ask if there is any temporary ambient condi tion such as splashing water, mist or fog.
3. Ask if there is any object such as ice, frost or dirt obstructing the side radar.
Is any of above conditions seen?
YES >> Explain to the customer about the differ ence between the blockage detection function and the
indication when the malfunction is detected and tell them “This is not malfunction”.
NO >> INSPECTION END
DTC No. Trouble diagnosis name DTC detecting condition Possible cause
C1B55 RADAR BLOCKAGE Sid e radar is blocked. Stain or foreign materials is deposit-
ed.
