6. Connect the other meter test lead to wire 11S at
terminal block 2 (TB2).
a. Continuity should be measured.
NOTE: Where terminal block is not present, place meter
test lead on the wire at the termination point. If
necessary, use a small paper clip to probe beside the
wire so as not to damage the terminal in the connector.
Results
1. If Continuity was not measured, repair or replace
the wire harness.
2. If Continuity was measured, refer back to the flow
chart.
Test 52 – Check Idle Control Switch
(SW2)
Procedure
1. Set DMM to measure resistance.
2. Disconnect wire 0 and wire 83 from the idle control
switch (SW2).
3. See Figure 4-58. Connect meter test leads across
both terminals of SW2.
a. In the OFF position Infinity should be
measured.
b. In the ON position Continuity should be
measured.
Results
1. If the switch fails step 3 replace it.
2. If the switch is good refer back to the flow chart.
