600-4 Hydraulic Oil
Temperature Sensor Voltage
Always inspect wiring harness connectors that are involved in the circuit.
Is Below Normal or Shorted
Poor connections can often be the cause of a problem in an electrical
Low
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 wiring harness connection to
identify the correct wiring harness to replace.
Tag all wiring harnesses to aid in installation.
Perform this test only if condition is active.
DIAGNOSTIC CODE SET CONDITION
Transmission ECM detects that voltage for the hydraulic oil temperature sensor
signal is low.
POSSIBLE CAUSE
Hydraulic oil temperature sensor is faulty.
Lower cab wiring harness is shorted to ground.
Engine wiring harness is shorted to ground.
Transmission ECM.
Test Step 1. Check for Active
Diagnostic Codes.
Connect MSD. Select Transmission
Diagnostic Code 600-4 Active -
Proceed to Test Step 2.
924H and check for active diagnostic
codes (WP 0008).
Diagnostic Code 600-4 Not Active -
Troubleshooting is complete.
Test Step 2. Test for Faulty Hydraulic
Oil Temperature Sensor.
1. Turn ignition switch and battery
disconnect switch to OFF position
(TM 5-3805-298-10).
2. Remove left engine access panel
(WP 0350).
3. Disconnect connector EN-C18
(WP 0012, Figure 73) from
hydraulic oil temperature sensor.
4. Turn battery disconnect switch and
ignition switch ON (TM 5-3805-
298-10).
