MALFUNCTION
TEST OR INSPECTION
CORRECTIVE ACTION
271-5 Action Alarm Voltage
8. Remove jumper wire from
Below Normal - Contin-
between pin 1 and 2 on instru-
ued
ment panel harness action alarm
connector E-C3 (WP 0018, Figure
81).
9. Disconnect dash monitor connec-
tor E-C7 (WP 0018, Figure 5)
from instrument panel (WP 0262).
10. Using digital multimeter (WP
1. If continuity is NOT found, replace
0296), test for continuity between
instrument panel harness
pin 1 on instrument panel harness
(WP 0260). Ensure all harness
action alarm connector E-C3
connectors are reconnected. Ver-
(WP 0018, Figure 81) and pin 4
ify correct operation of machine
on dash monitor connector E-C7
(TM 5-2410-241-10).
(WP 0018, Figure 5).
2. If continuity is found, proceed to
step 11.
11. Using digital multimeter (WP
1. If continuity is NOT found, replace
0296), test for continuity between
instrument panel harness
pin 2 on instrument panel harness
(WP 0260). Ensure all harness
action alarm connector E-C3
connectors are reconnected. Ver-
(WP 0018, Figure 81) and pin 2
ify correct operation of machine
on dash monitor connector E-C7
(TM 5-2410-241-10).
(WP 0018, Figure 5).
2. If continuity is found, proceed to
step 12.
12. Using digital multimeter (WP
1.
If continuity is found, replace
0296), test for continuity between
instrument panel harness
pin 4 on dash monitor connector
(WP 0260). Ensure all harness
E-C7 (WP 0018, Figure 5) and all
connectors are reconnected. Ver-
other pins in dash monitor con-
ify correct operation of machine
nector E-C7 (WP 0018, Figure 5).
(TM 5-2410-241-10).
2.
If continuity is NOT found, replace
dash monitor ECM (WP 0262).
Ensure all harness connectors
are reconnected. Verify correct
operation of machine (TM 5-2410-
241-10).
324-3 Action Lamp Voltage
1. Connect MSD (WP 0016). Select
1. If active 324-3 code is present,
Above Normal
CAT Monitoring System D7R
proceed to step 2.
ECM and check for Diagnostic
2. If no active codes are present,
Codes or Event Codes
problem does NOT exist at this
time. Resume normal operation.
2. Turn ignition switch and battery
disconnect switch to OFF position
(TM 5-2410-241-10).
3. Disconnect dash monitor connec-
tor E-C7 (WP 0018, Figure 5)
from instrument panel (WP 0262).
