INSPECTION
PROCEDURE
1. INSPECT WINDSHIELD WIPER SWITCH ASSEMBLY (w/ Auto Wiper System)
(a) Measure the resistance according to the value(s) in the table below.
| *A | for Type A | *B | for Type B |
| *a | Component without harness connected (Windshield Wiper Switch Assembly) | - | - |
HINT:
If the result is not as specified, replace the windshield wiper switch assembly.

| 13 (+S) - 5 (E) | AUTO | |
| 11 (+1) - 5 (E) | LO | |
| 12 (+2) - 5 (E) | HI |
| Tester Connection | Switch Condition | Specified Condition |
|---|---|---|
| 15 (WF) - 5 (E) | ON | Below 1 Ω |
| OFF | 10 kΩ or higher |
| Tester Connection | Switch Condition | Specified Condition |
|---|---|---|
| 4 (VR) - 5 (E) | P1 | 1102 to 1218 Ω |
| P2 | 570 to 630 Ω | |
| P3 | 256.5 to 283.5 Ω | |
| P4 | Below 1 Ω |
