Code No. C1752: Radar Temperature Out of Range
 
 
cautionWhen the ACC/FCM-ECU is replaced, calibrate the radar (refer to ).
 
 
OPERATION
The ACC/FCM-ECU monitors temperature at the radar.
 
 
DIAGNOSIS CODE SET CONDITION
Check Condition
  • Ignition switch is "ON" position.
Judgement Criterion
  • The temperature which the ACC/FCM-ECU detects at the radar is below -40°C or over 105°C.
 
 
PROBABLE CAUSES
  • The ACC/FCM-ECU remains protected.
  • Severe driving condition (e.g. driving under high load)
  • Malfunction of ACC/FCM-ECU

 
 
DIAGNOSIS PROCEDURE
STEP 1. Check the radar temperature (high or low).
(1) Turn the ignition switch to "LOCK" (OFF) position and then wait for a while so that the radar at the ACC/FCM-ECU remains at appropriate temperature.
noteThe radar temperature can be checked by "Item No.2: ECU temperature" in the M.U.T.-IIISE data list.
(2) Turn the ignition switch from "LOCK" (OFF) position to "ON" position.
(3) Press the ACC ON/OFF switch to turn the ACC system to ON.
(4) On completion, check that the diagnosis code is set again.
Is diagnosis code No.C1752 set?
Replace the ACC/FCM-ECU (Refer to ).
This diagnosis is complete (Protection is deactivated).
