(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 |
