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