Relay
1. INSPECT TAILLIGHT RELAY (TAIL)
(a) Remove the taillight relay from the main body ECU (driver side junction block assembly). |
 |
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection | Condition | Specified Condition |
|---|---|---|
3 - 5 |
Battery voltage applied to terminals 1 and 2 |
Below 1 Ω |
Battery voltage not applied between terminals |
10 kΩ or higher |
|
3 - 4 |
Battery voltage applied to terminals 1 and 2 |
10 kΩ or higher |
Battery voltage not applied between terminals |
Below 1 Ω |
If the result is not as specified, replace the taillight relay.
2. INSPECT FOG LIGHT RELAY (FOG)
(a) Remove the fog light relay from the main body ECU (driver side junction block assembly). |
