Connect one meter test lead to pin location J2-10 Wire 44S
of the connector just removed. Be careful not to damage the
pin connectors with the test leads. Connect the other meter
test lead to Wire 44S at Terminal Block 2 (TB2). CONTINUITY
should be measured.

3. Connect one meter test lead to pin location J2-12 Wire 11S. Be

careful not to damage the pin connectors with the test leads.
Connect the other meter test lead to Wire 11S at Terminal
Block 2 (TB2). CONTINUITY should be measured.

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 a voltmeter to measure resistance.

2. Disconnect Wire 0 and Wire 83 from the Idle Control Switch

(SW2).

3. Connect meter test leads across both terminals of SW2. See

Figure 6-59.

4. In the OFF position the meter should read INFINITY or Open.

In the ON position the meter should read CONTINUITY or
Closed.

RESULTS:
1. If the switch fails Step 4 replace it.

2. If the switch is good refer back to the flow chart.

TEST 53 - CHECk IdLE CONTROL WIRINg

PROCEDURE:

1. Set a voltmeter to measure resistance.

2. Disconnect Wire 0 from the Idle Control Switch (SW2).

3. Connect one meter test lead to Wire 0. Connect the other meter

test lead to frame ground. CONTINUITY should be measured.
If continuity is not measured repair or replace Wire 0 between
SW2 and the ground terminal.

4. Disconnect Wire 83 from SW2. Disconnect the J2 connector

from the printed circuit board.

5. Connect one meter test lead to Wire 83 previously removed

from SW2. Connect the other meter test lead to pin location
J2-2 on the J2 connector. See Figure 6-60. Be careful not to
damage the pin connectors with the test leads. CONTINUITY
should be measured. If CONTINUITY is not measured repair or
replace Wire 83 between the J2 connector and Terminal Block
or between the Terminal Block and SW2.
