1. Detach the main switch connector from the
harness connector.
When detaching the connector, do not pull by
the cables. This way the cables might discon-
nect from the terminals inside the connector
itself.
2. Check to see if any cables are disconnected
from their terminal inside the connector.
Reconnect, if necessary.
NOTE:
If the connector is blocked up with mud or dust,
clean it with a jet of compressed air.
3. Use the connection table to check the combi-
nation of colours for continuity (closed circuit).
In this example, continuity is as follows:
“R” and “Br” are continuous when the switch is
at ON.
“L” and “R/B” are continuous when the switch
is at ON.
“R” and “L” are continuous when the switch is
at PARK.
Note that there is no continuity (open circuit)
for any of the combinations of a colour differ-
ent from those mentioned and when the
switch is at OFF.
4. Check the switch component for continuity
between “R” and “Br”.
