Toyota Corolla Cross: On-vehicle Inspection
ON-VEHICLE INSPECTION
PROCEDURE
1. INSPECT AUTOMATIC LIGHT CONTROL SENSOR
(a) Disconnect the h1 automatic light control sensor connector.
| (b) Measure the voltage and resistance according to the value(s) in the table below. Standard Voltage:
Standard Resistance:
If the result is not as specified, there may be a malfunction on the wire harness side. |
|
(c) Connect the h1 automatic light control sensor connector.
(d) Connect an oscilloscope to terminals h1-2 (CLTE) and h1-4 (CLTS) of the automatic light control sensor connector and check the waveform.
