(a) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection | Condition | Specified Condition |
3 - 4 |
Battery voltage applied between terminals 1 and 2 |
10 kΩ or higher |
3 - 4 |
Battery voltage not applied between terminals 1 and 2 |
Below 1 Ω |
3 - 5 |
Battery voltage applied between terminals 1 and 2 |
Below 1 Ω |
3 - 5 |
Battery voltage not applied between terminals 1 and 2 |
10 kΩ or higher |
If the result is not as specified, replace the DEF relay. |
