3. At MSD, check for active
1283-4 Ejector Lever Position Sensor
1283-04 Ejector Lever
diagnostic codes (WP 0008).
Voltage Below Normal Becomes
Position Sensor Voltage
Inactive Troubleshooting complete.
Below Normal Continued
Proceed to step 4.
1283-4 Ejector Lever Position Sensor
Voltage Below Normal Remains
Active Repeat troubleshooting from
the beginning.
4. Install right trim panels on ROPS
(WP 0494).
NOTE
1283-08 Ejector Lever
Position Sensor Abnormal
Always inspect harness connectors that are involved in the circuit. Poor
Signal
connections can often be the cause of a problem in an electrical circuit.
Verify that all connections in the circuit are clean and secure and that all
connections are in good condition. If a problem with the connection is
found, correct the problem and verify that this malfunction or diagnostic
code is active before performing this procedure.
Perform open or short-circuit test at each harness connection to identify
the correct harness to replace.
Tag all wiring harnesses to aid in installation.
Perform this test only if condition is active.
DIAGNOSTIC CODE SET CONDITION
Transmission/Chassis ECM Detects Abnormal Frequency or Pulse Width on
Ejector Lever Sensor Circuit R750.
POSSIBLE CAUSE
Fuse Panel Wiring Harness High Resistance or Open.
Main Cab Wiring Harness High Resistance or Open.
Implement Control Joystick.
Transmission/Chassis ECM.
Test Step 1. Check for Other Active
Codes.
1. Turn battery disconnect switch and
ignition switch to ON position
(TM 5-3805-296-10).
2. Connect MSD. Select
1283-3 Ejector Lever Position Sensor
Transmission 621G and check for
Voltage Above Normal Active
active diagnostic codes:
Diagnose and repair active code as
a. 1283-3 Ejector Lever Position
described in this work package.
Sensor Voltage Above
1283-4 Ejector Lever Position Sensor
Normal.
Voltage Below Normal Active
b. 1283-4 Ejector Lever Position Diagnose and repair active code as
Sensor Voltage Below Normal. described in this work package.
Only 1283-8 Ejector Lever Position
Sensor Abnormal Signal Active
Proceed to Test Step 2.
