FLASHER UNIT
Inspection
1. Check for continuity between terminals of the flasher unit.
0: Indicates continuity X: No continuity
Note
l Set the tester to the xl,OOOQ range.
2. If continuity is not as specified, replace the switch.
DOOR LOCK TIMER UNIT
inspection
1. Check for continuity between terminals.
a-h X c-e 0 e-h 0
b-c X c-f 0 f-h X
0: Continuity X: Non-continuity
Note
l Set the tester to x1000Q range.
l Continuity includes the state with resistance, and
Non-continuity means insulated.
2. Connect the battery voltage to the “b” terminal and the
ground to the “a” terminal. Then, short circuit the “h” and
“d” terminals between the “h” and “c” terminals, and check
that the relay clicks.
