Electronic Troubleshooting

The sequence for the flash code is started by cycling

the keyswitch twice within a period of 3 seconds.

After a delay of 2 seconds, the  “Shutdown” lamp will

flash once for half a second. This sequence indicates

the start of the active fault codes. After a further delay

of 2 seconds, the “Warning”  lamp will flash

repeatedly in order to indicate the active diagnostic

codes. Each flash will be on for half a second and off

for 300 ms. The “Warning”  lamp will remain off for 2

seconds between each digit of a code. If there is

more than one active diagnostic code, the

“Shutdown” lamp will go off for 2 seconds. The lamp

will then come on for half a second. The  “Warning”

lamp will go off for 2 seconds before starting the next

code. If there are no active diagnostic codes, the

“Warning” lamp will flash the code “551” . Refer to

Troubleshooting Guide, “No Diagnostic Code

Detected”.

As an example, an active diagnostic code of  “21”  is

indicated by the “Warning”  lamp operating in the

following sequence:

•   On for 500 ms

•   Off for 300 ms

•   On for 500 ms

•   Off for 2000 ms

•   On for 500 ms

•   Off

Timing of the flash codes

After all of the active diagnostic codes have been

displayed, the “Shutdown”  lamp will go off for 2

seconds. The “Shutdown”  lamp will flash twice in

order to indicate the start of the sequence that will

display the logged diagnostic codes. The process for

flashing logged diagnostic codes is identical to the

process for flashing active diagnostic codes.

Note: If there are no logged codes, the  “551”  code

should be flashed again.

Electronic Troubleshooting

After all of the codes have been displayed, the

“Shutdown” lamp will flash three times in order to

indicate that there are no further codes. Cycling the

keyswitch twice within a period of 3 seconds will start

the process again. All codes will be displayed in

ascending numerical order.

Use the electronic service tool to read the parameters

in the suspect ECM. Record the parameters in the

suspect ECM. Install the flash file into the new ECM.

After the ECM is installed on the engine, the

parameters must be programmed into the new ECM.

Note: When a new ECM is not available, an ECM can

be used from an engine that is not in service. The

ECM must have the same serial number suffix.

Ensure that the replacement ECM and the part

number for the flash file match the suspect ECM. Be

sure to record the parameters from the replacement

ECM. Use the “Copy Configuration ECM

Perform the following procedure in order to replace

the ECM.

NOTICE

Care  must be  taken to  ensure  that fluids  are  con-

tained  during   performance  of  inspection,   mainte-

nance, testing, adjusting and repair of the product. Be

prepared to  collect the fluid  with suitable containers

before  opening any  compartment  or disassembling

any component containing fluids.

1. Connect the electronic service tool to the

diagnostic connector.

2. Use the “Copy Configuration ECM Replacement”

function from the electronic service tool. If the

“Copy Configuration” is successful, proceed to

Step 4. If the “Copy Configuration” failed, proceed

to Step 3.

Dispose of all fluids according to local regulations and

mandates.

records.

Contaminants may cause  rapid wear and  shortened

component life.

3. Record the following parameters:

•   Record all of the parameters on the

“Configuration”  screen.

The engine is equipped with an Electronic Control

Module (ECM). The ECM contains no moving parts.

Follow the troubleshooting procedures in this manual

in order to be sure that replacing the ECM will correct

the fault. Verify that the suspect ECM is the cause of

the fault.

•   Record all of the parameters on the “Throttle

Configuration”  screen.

•   Record all of the parameters on the “Mode

Configuration”  screen.

Note: Ensure that the ECM is receiving power and

that the ECM is properly grounded before

replacement of the ECM is attempted. Refer to the

schematic diagram.

•   Record the serial numbers of the electronic unit

injectors. The injector serial numbers are

shown on the “Injector Trim Calibration”

screen.

A test ECM can be used in order to determine if the

ECM on the engine is faulty. Install a test ECM in

place of the suspect ECM. Install the flash file with the

correct part number into the test ECM. Program the

parameters for the test ECM. The parameters must

match the parameters in the suspect ECM. Refer to

the following test steps for details. If the test ECM

resolves the fault, reconnect the suspect ECM. Verify

that the fault returns. If the fault returns, replace the

ECM.

Note: If the parameters cannot be read, the

parameters must be obtained elsewhere. Some

parameters are stamped on the engine information

plate, but most parameters must be obtained from the

TMI data on the Perkins  secured web site.

4. Remove power from the ECM.

5. Remove the ECM. Refer to Disassembly and

Assembly, “Electronic Control Module - Remove

and Install”.

Note: If an ECM is used as a test ECM, select  “Test

ECM Mode” on the electronic service tool before the

engine serial number is entered.
