FORWARD RECOGNITION CAMERA SYSTEM, Diagnostic DTC:C1AAE

DTC Code DTC Name
C1AAE Heater Circuit

DESCRIPTION

The forward recognition camera controls the flow of current to the camera heater (forward recognition hood).

If the forward recognition camera detects a malfunction in the camera heater (forward recognition hood) circuit, DTC C1AAE is stored.

DTC No. Detection Item DTC Detection Condition Trouble Area
C1AAE Heater Circuit

    Either of the following conditions is met after 3 seconds have elapsed since the ignition switch was turned to ON:

  • While a camera heater (forward recognition hood) ON request is being sent, short to +B detected in the camera heater (forward recognition hood) circuit for 5 seconds or more.

  • While a camera heater (forward recognition hood) ON request is not being sent, open or short to ground detected in the camera heater (forward recognition hood) circuit for 5 seconds or more.

  • Camera heater (Forward recognition hood)

  • Forward recognition camera

  • Harness or connector

CAUTION / NOTICE / HINT

Note


  • Inspect the fuses for circuits related to this system before performing the following procedure.

  • When replacing the forward recognition camera, always replace it with a new one. If a forward recognition camera which was installed to another vehicle is used, the information stored in the forward recognition camera will not match the information from the vehicle. As a result, a DTC may be stored.

  • If the forward recognition camera has been replaced with a new one, be sure to perform forward recognition camera adjustment.

PROCEDURE


  1. CHECK FOR DTCs (FORWARD RECOGNITION CAMERA SYSTEM)


    1. Clear the DTCs.


      Chassis > Front Recognition Camera > Clear DTCs

    2. Perform the following procedure.

      Tech Tips

      If the following procedure is not performed, the previously output DTC cannot be detected.


      1. Turn the ignition switch to ON and wait 8 seconds or more.

    3. Check for DTCs.


      Chassis > Front Recognition Camera > Trouble Codes

  2. INSPECT CAMERA HEATER (FORWARD RECOGNITION HOOD)


    1. Turn the ignition switch off.

    2. Disconnect the V16 camera heater (forward recognition hood) connector.

      *a Component without harness connected - -

    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      V16-2 (HTR) - A-2 Always Ignition switch off 36.1 to 39.9 Ω
      V16-1 (IG1) - A-1 Always Ignition switch off Below 1 Ω
      A-1 - A-2

      • Positive (+) tester probe → A-1

      • Negative (-) tester probe → A-2

      Tech Tips

      If the tester probes are connected to the wrong terminals, due to the existence of the diode, current will not flow and the result will be the same as for an open circuit.

      		 Ignition switch off Below 1 Ω

    4. Connect the V16 camera heater (forward recognition hood) connector.

    2. Measure the voltage according to the value(s) in the table below.

      Standard Voltage
      Tester Connection Condition Specified Condition
      V16-1 (IG1) - Body ground Ignition switch ON 11 to 14 V

  4. CHECK HARNESS AND CONNECTOR (CAMERA HEATER (FORWARD RECOGNITION HOOD) - FORWARD RECOGNITION CAMERA)


    1. Disconnect the V16 camera heater (forward recognition hood) connector.

    2. Disconnect the V6 forward recognition camera connector.

    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      V16-2 (HTR) - V6-1 (HTR) Always Below 1 Ω
      V16-2 (HTR) or V6-1 (HTR) - Body ground Always 10 kΩ or higher

    4. Connect the V6 forward recognition camera connector.

    5. Connect the V16 camera heater (forward recognition hood) connector.
