Failure code

Failure

Hydraulic Oil Sensor Short Circuit
(Pump controller system)

L01

DGH2KB

Detail of failure

Signal voltage of hydraulic oil temperature sensor circuit is below 1 V, so pump controller deter-
mines that circuit shorts.

Action of con-

troller

If cause of failure disappears, machine becomes normal by itself.

Problem on

machine

Regardless of the hydraulic oil temperature, hydraulic oil temperature gauge meter is equivalent to
50 degrees.

Related infor-

mation

Signal voltage from hydraulic oil temperature sensor can be checked with monitoring function.
(Code: 04402: Hydraulic oil temperature sensor voltage)

Method of reproducing failure code: Start engine.

Cause

Procedure, measuring location, criteria and remarks

Defective hydraulic oil tempera-
ture sensor
(internal open or short circuit)

1. Turn starting switch to OFF position.
2. Disconnect connector P22 and connect T-adapters to male side.

Between P22 (male) (1)
and (2)

80 °C

Resistance

Approx. 6.5 k

100 °C

Resistance

Approx. 3.5 k

Between P22 (male) (2) and ground

Resistance

Min. 1 M

Open circuit or short circuit or
ground fault or hot short circuit in
wiring harness

1. Turn starting switch to OFF position.
2. Disconnect connector P22 and connect T-adapters to female side.
3. Turn starting switch to ON position.

If voltage is 0 V, wiring harness has open circuit, ground fault, or short cir-
cuit, and if voltage is 24 V, wiring harness has hot short circuit.

Voltage of about 5 V is applied to temperature sensor signal lines through
resistor in pump controller.

Between P22 (female) (1) and (2)

Voltage

Approx. 5 V

Short circuit or ground fault in wir-
ing harness

1. Turn starting switch to OFF position.
2. Disconnect connector C01 and connect T-adapters to female side.

Use Temperature-Resistance characteristics table for troubleshooting on
cause 1 as resistance criteria.

If resistance is above 1 M

, wiring harness has open circuit. If resistance

is below 1

, wiring harness has short circuit.

Between C01 (female) (29) and (46)

Resistance

Ground fault in wiring harness
(contact with ground circuit)

If no failure is found by check on cause 2, this check is not required.

1. Turn starting switch to OFF position.
2. Disconnect connectors C01 and P22, and connect T-adapters to either

female side.

Between C01 (female) (29) and ground, or
between P22 (female) (2) and ground

Resistance

Min. 1 M

5 Defective pump controller

If no failure is found by above checks, pump controller is defective. (Since this
is an internal defect, troubleshooting cannot be performed.)
