Optical sensor System InspectionAKS007F5
1. CHECK OPTICAL SENSOR INPUT SIGNAL
With CONSULT-II
Select “BCM” on CONSULT-II. With “HEAD LAMP” data monitor,
make sure “OPTICAL SENSOR”, check difference in the voltage
when auto light sensor is illuminated and not illuminated.
CAUTION:
Optical sensor must be securely subjected to work lamp light. If
optical sensor is insufficiently illuminated, the measured value
may not satisfy the standard.
Without CONSULT-II
1. Turn ignition switch ON.
2. Check voltage between BCM harness connector M3 terminal 14 (P) and ground.
CAUTION:
Optical sensor must be securely subjected to work lamp light. If
optical sensor is insufficiently illuminated, the measured value
may not satisfy the standard.
OK or NG
OK >> INSPECTION END
NG >> GO TO 2.
2. CHECK OPTICAL SENSOR POWER SUPPLY CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect BCM connector and optical sensor connector.
3. Check continuity (open circuit) between BCM harness connector M3 terminal 17 (Y/G) and optical sensor harness connector M37
terminal 1 (Y/G).
4. Check continuity (short circuit) between BCM harness connector M3 terminal 17 (Y/G) and ground.

OIL PRESSURE CHECK
WARNING:

Be careful not to get burn yourself, as engine oil may be hot.

Oil pressure check should be done in “Parking position”.
1. Check the engine oil level. Refer to LU-7, "
ENGINE OIL LEVEL" .
2. Remove front engine undercover with power tool.
3. Disconnect harness connector at oil pressure sensor, and remove oil pressure sensor using deep socket (commercial ser-
vice tool).
CAUTION:
Do not drop or shock oil pressure switch.
4. Install the oil pressure gauge [SST] and hose [SST].
5. Start the engine and warm it up to normal operating temperature.
6. Check the engine oil pressure with engine running under no-load. NOTE:
When the engine oil temperature is low, the engine oil pressure becomes high.
Engine oil pressure [Engine oil temperature at 80 °C (176 °F)]
If difference is extreme, check engine oil passage and oil pump for engine oil leaks.
7. After the inspections, install oil pressure switch as follows:
