INTERMITTENT PROBLEMS

Check the following for intermittent problems

 Poor mating of the connector halves/damage of connector locking

 Terminals not fully seated in the connector body

 Damage of harness and terminals

 Connector pin separation from wire

 Corrosion on pin contact points

IQA/IMA CODE PROGRAMMING

An ECU controlled engine needs precise metering of fuel. Due to manufacturing tolerances, each injector

deviates slightly from its idealized behavior. Thus, each injector has a correction factor, which is engraved

on top of it, in the form of a 8-character alphanumeric code , out of which the last character "W" is a

dummy value. This is known as an IQA code/IMA code. For optimal performance of the engine, the ECU

needs to know the IQA code/IMA code of each injector. This information is programmed into the ECU

when the vehicle is manufactured. However, if you need to replace an injector(s), then the IQA code/IMA

code for that new injector has to be updated in the ECU. The cylinder number starts from the right side of

the vehicle.

As a first step, you need to select the cylinder number of the injector being replaced. After the cylinder

number is selected by clicking on the check-button next to the number, the IQA code/IMA code should be

entered in the box provided.

Click the button to the right of the text box. If the Injector code is valid and accepted by the ECU, a

message is displayed, indicating that the operation is performed successfully.

A message “Invalid IQA code” will be displayed , if an incorrect IQA/IMA code is keyed in. IQA codes are

case sensitive.

Programming IQA codes is an extremely important activity. In order to ensure that the correct code has

been entered and that it has been entered in the correct cylinder, SMART tester allows you to verify the

codes that you have entered.

Caution

Even though on the injector, 8 character alphanumeric code is engraved , while writing the IQA

code only the first 7 digits need to be entered

`

Select an injector, and click the button below the ”Verify” line in figure. The IQA codes present in the ECU

will be read back and displayed in the text box before this button. It is recommended that you carry out

the verification activity whenever you change an IQA code.

PLEASE ENSURE TO PROGRAM IQA/IMA CODES WHEN YOU REPLACE AN INJECTOR, ECU or ENGINE.

The following are the fonts of the alphanumeric characters of the IQA/IMA code, as etched on the

injectors.

EMS ECU FLASHING

The EMS ECU required to be flashed in the following conditions

BLANK ECU

 Procure blank EMS ECU from spare part dept.

 Check for the correct/latest part no in parts catalogue/Technical Service Bulletins.

Flash the EMS ECU dataset with a latest dataset as per TSB or at the advice of TEKline.

NOTES -

1. Flash the EMS ECU with the correct/latest dataset. The matrix of the vehicles and the related latest

dataset will be released through TSB - if in doubt ask the TEKline.

2. Wrong dataset flashing may result in vehicle not starting and can lead to ECU failure.
