DESCRIPTION
The forward recognition camera controls the flow of current to the forward recognition with heater hood sub-assembly.
If the forward recognition camera detects a malfunction in the forward recognition with heater hood sub-assembly circuit, it will store this DTC.
DTC No. | Detection Item | DTC Detection Condition | Trouble Area |

PROCEDURE
1. | CHECK FOR DTCs |
(a) Clear the DTCs.
Chassis > Front Recognition Camera > Clear DTCs(b) Make sure that the DTC detection conditions are met.
HINT:
If the detection conditions are not met, the system cannot detect the malfunction.
(c) Check for DTCs.

A | USE SIMULATION METHOD TO CHECK |
|
2. | INSPECT FORWARD RECOGNITION WITH HEATER HOOD SUB-ASSEMBLY |
(a) Turn the engine switch off.
(b) Disconnect the forward recognition with heater hood sub-assembly connector. |
|
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection | Condition | Specified Condition |
---|---|---|
1 (IG1) - 2 (HTR) | Engine switch off | 28.5 to 31.5 Ω |
(d) Connect the forward recognition with heater hood sub-assembly connector.
NG | REPLACE FORWARD RECOGNITION WITH HEATER HOOD SUB-ASSEMBLY |
|
3. | CHECK HARNESS AND CONNECTOR (POWER SOURCE VOLTAGE) |
(a) Disconnect the P14 forward recognition with heater hood sub-assembly connector. |
|
(b) Measure the voltage according to the value(s) in the table below.
Standard Voltage:
Tester Connection | Condition | Specified Condition |
---|---|---|
P14-1 (IG1) - Body ground | Engine switch on (IG) | 8 to 16 V |
Engine switch off | Below 1.5 V |
(c) Connect the P14 forward recognition with heater hood sub-assembly connector.
NG | REPAIR OR REPLACE HARNESS OR CONNECTOR (POWER SOURCE CIRCUIT) |
|
4. | CHECK HARNESS AND CONNECTOR (FORWARD RECOGNITION WITH HEATER HOOD SUB-ASSEMBLY - FORWARD RECOGNITION CAMERA) |
(a) Disconnect the P14 forward recognition with heater hood sub-assembly connector.
(b) Disconnect the P5 forward recognition camera connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection | Condition | Specified Condition |
---|---|---|
P14-2 (HTR) - P5-1 (HTR) | Always | Below 1 Ω |
P14-2 (HTR) or P5-1 (HTR) - Body ground | Always | 10 kΩ or higher |
(d) Connect the P5 forward recognition camera connector.
(e) Connect the P14 forward recognition with heater hood sub-assembly connector.
OK | REPLACE FORWARD RECOGNITION CAMERA |
NG | REPAIR OR REPLACE HARNESS OR CONNECTOR (FORWARD RECOGNITION WITH HEATER HOOD SUB-ASSEMBLY - FORWARD RECOGNITION CAMERA) |
