Without connecting the relay:
A) Check the continuity across the yellow connector PIN 85 and the central unit PIN 19.
PIN 85 (purple/black) - PIN 19 = 0
Ω
(continuity).
B) Make sure it is insulated from the ground.
PIN 19 - PIN 23 = 1 M
Ω
(infinitive)
Restore:
A) Purple/black cable continuity
B) The purple/black insulation from the ground
Connect the relay and make sure the battery voltage is present across PIN 19 and PIN 23 when the key
switch is on the “ON” position.
PIN 19 - PIN 23 = battery voltage with the key switch on “ON”.
Perform the test once again with the central unit connected, cold engine and the key switch on the
“ON” position. PIN 19 - PIN 23 = battery voltage.
In case the anomaly persists, replace the central unit.
