2. | INSPECT FORWARD RECOGNITION WITH HEATER HOOD SUB-ASSEMBLY |
*a | Component without harness connected (Forward Recognition with Heater Hood Sub-assembly) |
(a) Disconnect the U20 forward recognition with heater hood sub-assembly connector.
(b) 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 |
NG | REPLACE FORWARD RECOGNITION WITH HEATER HOOD SUB-ASSEMBLY |
|
3. | CHECK HARNESS AND CONNECTOR (POWER SOURCE VOLTAGE) |
*a | Front view of wire harness connector (to Forward Recognition with Heater Hood Sub-assembly) |
(a) Measure the voltage according to the value(s) in the table below.
Standard Voltage:
Tester Connection | Condition | Specified Condition |
---|---|---|
U20-1 (IG1) - Body ground | Engine switch on (IG) | 8 to 16 V |
Engine switch off | Below 1.5 V |
NG | REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
4. | CHECK HARNESS AND CONNECTOR (FORWARD RECOGNITION WITH HEATER HOOD SUB-ASSEMBLY - FORWARD RECOGNITION CAMERA) |
(a) Disconnect the U14 forward recognition camera connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection | Condition | Specified Condition |
---|---|---|
U20-2 (HTR) - U14-1 (HTR) | Always | Below 1 Ω |
U20-2 (HTR) or U14-1 (HTR) - Body ground | Always | 10 kΩ or higher |
OK | REPLACE FORWARD RECOGNITION CAMERA |
NG | REPAIR OR REPLACE HARNESS OR CONNECTOR |
