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 |
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. |
