1. Turn ignition switch and battery
disconnect switch to OFF position
(TM 5-3805-298-10).
2. Disconnect connector E-C3
(WP 0012, Figure 16) from engine
coolant temperature sensor.
3. Turn battery disconnect switch ON
(TM 5-3805-298-10).
4. On MSD, select C6.6 924 and
110-4 Engine Coolant Temperature
check for active diagnostic codes
Sensor Signal Voltage Is Below
Normal Remains Active - Proceed to
Test Step 3.
110-4 Engine Coolant Temperature
Sensor Signal Voltage Is Below
Normal Becomes Inactive - Replace
engine coolant temperature sensor
(WP 0248).
Proceed to Test Step 4.
Test Step 3. Test for Shorted Engine
Control Wiring Harness.
1. Turn ignition switch and battery
disconnect switch to OFF position
(TM 5-3805-298-10).
2. Remove right engine access panel
(WP 0348).
3. Disconnect connector E-C4
(WP 0012, Figure 10) from engine
ECM connector J2.
4. Using digital multimeter
