Resistance:
| Tester Connection | Condition | Specified Condition |
|---|---|---|
| T7-13 (SIG1) - T7-9 (GND3) | Mayday switch not pressed | 410 to 414 Ω |
| T7-13 (SIG1) - T7-9 (GND3) | Mayday switch pressed | 81 to 83 Ω |
(b) Check the operation (indicator).
(1) Check that each indicator illuminates when 2 dry cell batteries are connected to the map light assembly connector terminals as shown in the illustration.
| *a | Component without harness connected (Map Light Assembly) | *b | Two 1.5 V dry cell batteries |
NOTICE:
Do not apply more than 3 V.
OK:
| Tester Connection | Condition | Specified Condition |
|---|---|---|
| T7-6 (IND1) - T7-9 (GND3) | Positive (+) dry cell battery - Negative (-) dry cell battery | HELP RED indicator illuminates |
| T7-7 (IND2) - T7-9 (GND3) | Positive (+) dry cell battery - Negative (-) dry cell battery | HELP GREEN indicator illuminates |
(c) Check that the HELP indicator illuminates when the battery is connected to the map light assembly connector terminals as shown in the illustration.
| *a | Component without harness connected (Map Light Assembly) | - | - |
OK:
| Tester Connection | Condition | Specified Condition |
|---|---|---|
