ON-VEHICLE INSPECTION
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. | |
