ON-VEHICLE INSPECTION
PROCEDURE
1. INSPECT FRONT WIPER DEICER RELAY
| (a) Measure the resistance according to the value(s) in the table below. Standard Resistance:
If the result is not as specified, replace the front wiper deicer relay. |
|
2. INSPECT DEFOGGER 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 is not applied between terminals 1 and 2 | Below 1 Ω |
| Auxiliary battery voltage is applied between terminals 1 and 2 | 10 kΩ or higher | |
| 3 - 5 | Auxiliary battery voltage is not applied between terminals 1 and 2 | 10 kΩ or higher |
| Auxiliary battery voltage is applied between terminals 1 and 2 | Below 1 Ω | |
| 4 - 5 | Always | 10 kΩ or higher |
If the result is not as specified, replace the defogger relay.
