3. Check for External Leaks

A. Check for external leaks.

Inspect the fuel lines from the

pump to the fuel manifold.Check for pinched lines or

leaking lines.

External

leaks

Result:A leak or pinched line was not

found.


Result:A leak or pinched line was found.

Repair all damaged lines or leaking lines.

Perform the "ARD Ignition Test" by usingCat ET. Refer to System Operation and

Testing and Adjusting , "ARD Fuel

System - Test". If the "ARD Ignition Test"

was successful, return the unit to service.

If the ARD ignition test was not

successful, Proceed to Test Step 4.

4. Check for Electrical Power at the Fuel

Priming Pump

A. Turn the keyswitch to the ON position. Do

not start the engine.

B. Establish communication between Cat ET

and the engine ECM. Select "Fuel Priming

Command Override" or use the manual

priming switch (if equipped) in order to

activate the ARD fuel pump. Refer to

Troubleshooting, "Cat ET Service Features"

for information about service features.

C. Check for voltage between pin 1 and pin 2

on the connector to the fuel priming pump.

Check the voltage while the pump is in

override. Voltage is not present unless the

pump is priming.

D. Deactivate the override.

E. Turn the keyswitch to the OFF position.

F. Check the voltage at the battery.

Voltage

within 3

VDC of thebattery

voltage

Result:The voltage at

the ARD fuel pump is

within 3 VDC of the

battery voltage.


Result:The voltage at

the ARD fuel pump is notwithin 3 VDC of the

battery voltage.

Refer to the machine

troubleshooting

schematic in order to

troubleshoot the circuit

for the priming pump.

STOP.

5. Check the Pump

A. Turn the engine "OFF".

B. Disconnect the ARD fuel line

from the pump.

C. Install the required parts listed in

Table 2 at the outlet port of the

pump.

D. Start the engine.

E. Select the "Aftertreatment Fuel

Pump Relay Override" in the"Engine #1 Aftertreatment

Controller" using Cat ET in order to

activate the pump.

F. Override the pump and record

the pressure from the pressure

gauge.

G. Deactivate the override.

H. Turn the keyswitch to the OFF

position.

I. The pressure must be within

specifications. The pump pressure

must be 1900 120 kPa (275.5

17.4 psi).

1900

120 kPa

(275.5

Result:The pump is not within

specifications.

Refer to Troubleshooting, "ARD

Fuel Supply - Test" for

troubleshooting information. STOP.

Result:The pump is within

specifications.

If you are troubleshooting a E1052

(1) or 3480-17 diagnostic code or a

E1053 (1) or 4077-17 diagnosticcode with an ETI of 2 or 3, proceed

to Test Step 6.

Result:The pump is within

specifications.

If you are troubleshooting an E1052

(2) or 3480-18 diagnostic code,

proceed to Test Step 7.

If you are troubleshooting a E1053
