7 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 an 6-character alphanumeric code. This is
known as an IQA code/IMA code. IQA stands for Injector Quantity Adjustment. 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.

7.1 IQA PROGRAMMING USING i-SMART

Follow the steps given below for programming the IQA code:

• Connect the i-SMART diagnostic tool with the vehicle using Garuda
• Turn the ignition ON
• Navigate to EMS ECU
1. Select ”WRITE DATA” from the left panel.

• Connect the other lead of voltmeter to selected test point. The vehicle ignition may need to
be turned ON to check voltage.

TESTING FOR CONTINUITY (RESISTANCE)

• Disconnect the power supply (battery, ignition switch OFF)
• Set the Multimeter Mode selector to measure resistance
• Connect one lead of the multimeter to one side of the circuit being tested
• Connect the other lead to the other end of the circuit being tested. Low or no resistance
means good continuity

• Disconnect the power supply (battery, ignition switch OFF)
• Set the Multimeter Mode selector to measure resistance, select resistance range
appropriately
• Connect one lead of the Multimeter to one side of the circuit being tested
• Connect the other lead to battery ground
• Starting at the fuse block, move / shake the wiring harness about six to eight inches apart
and look at the Multimeter display.
• If the Multimeter registers resistance value / audible beep, then there is a short to ground in
that area of the wiring harness.

TESTING FOR A SHORT TO GROUND ON FUSES POWERING SEVERAL LOADS

• Switch OFF the ignition and disconnect the battery.
• Referring the wiring diagrams, disconnect or isolate all items on the suspected fused
circuits.
• Replace the blown fuse.
• Supply power to the fuse by turning ON the ignition switch or re-connecting the battery as
applicable.
• Start connecting or energizing the components in the fuse circuit one at a time. When the
fuse blows, the circuit with the short to ground has been identified.
TESTING FOR A VOLTAGE DROP
• Set the Multimeter Mode selector to measure voltage, select voltage range appropriately
• Connect positive lead of voltmeter to one side of the circuit closest to battery positive
terminal.
• Connect other lead of voltmeter to the negative side of component/switch.
• Switch ON the component/load.
• The voltmeter will show the difference in voltage between the two points.

INTERMITTENT AND POOR CONNECTION

Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is
also possible for a sticking component or relay to cause a problem. First ask the customer for
details about the driving conditions, weather conditions, frequency of occurrence and trouble
symptoms and then try to recreate the trouble symptoms. Before replacing a component or
wiring assembly, check the following items.
• Connectors / inter—connector are fully locked
• Check for water traces in the fuse or relay box / connectors
• Any spread terminals or pin back out
• Terminals in the wiring assembly are fully seated into the connector/component and locked
into position
• Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an
intermittent problems
• Damaged connector/component casing exposing the item to dirt or moisture
• Wire insulation that has rubbed through, causing a short to ground
• Some or all of the wiring strands broken inside of the insulation
• Wiring broken inside of the insulation
Carry out the following checks with the connectors and components to confirm whether the
trouble symptom occurs.
• Gently shake the connector up, down and to the left and right
• Gently shake the wiring harness up, down and to the left and right.
• Gently shake the fuse / relay board, etc. by hand.
• Gently shake the wiring harness at the location of hanging and other moving parts
