Inspection Procedure

NOTE: When the distance control ECU is replaced with a new one, initialization must be performed (See INITIALIZATION ).

CONFIRM DESIGNATION INFORMATION (DISTANCE CONTROL ECU)
1. Confirm the designation information.
  1. Turn the engine switch on (IG).
  2. Turn the cruise control main switch on.
  3. Depress the brake pedal (brake switch on).
  4. With the brake pedal depressed, push the cruise control main switch to +RES 3 times within 3 seconds, and check that the buzzer sounds.
    NOTE: At this time, do not turn the headlight dimmer switch on. Due to the activation of the beam axis automatic adjustment mode, turning the headlight dimmer switch on may result in an incorrect setting. If the headlight dimmer switch is turned on by mistake, perform the beam axis adjustment again (See ADJUSTMENT ).
CHECK DTC (DYNAMIC RADAR CRUISE CONTROL SYSTEM)
1. Using the Techstream, enter the following menus: Powertrain / Radar Cruise / Trouble Code.
2. Clear the DTCs (See DTC CHECK/CLEAR ).
3. Perform the following to make sure the DTC detection conditions are met.
  HINT:
  
  If the detection conditions are not met, the system cannot detect the malfunction.
  1. Drive the vehicle at a speed of 40 km/h (25 mph) or more.
  2. Turn the cruise control main switch on to set the vehicle-to-vehicle distance control mode to the standby state.
4. Check for DTCs (See DTC CHECK/CLEAR ).
  OK: DTC P1617 is not output.
  
  HINT:
  
  If DTC P1617 is still output after replacing the distance control ECU, replace the ECM.
NG: REPLACE DISTANCE CONTROL ECU (See REMOVAL )
