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:
Tester Connection | Condition |
Specified Condition |
h1-1 (CLTB) - h1-2 (CLTE) |
Ignition switch off |
Below 1 V | h1-1 (CLTB) - h1-2 (CLTE) |
Ignition switch on (IG) | 11 to 14 V |
Standard Resistance:
Tester Connection | Condition |
Specified Condition |
h1-2 (CLTE) - Body ground |
Always | Below 1 Ω |
If the result is not as specified, there may be a malfunction on the wire harness side. |
