Explanation

Not all the parameters described need to be implemented in the control module. This varies from system to system.

Frozen values are parameter values that are stored when a diagnostic trouble code (DTC) is stored.

Bank 1 indicates cylinders 1-3 on 6 cylinder engines and all cylinders on 5-cylinder engines.

Bank 2 indicates cylinders 4-6 on 6-cylinder engines.

Condition, fuel trim bank X

Fuel trim can assume 5 different conditions

1. no fuel trim, the start conditions have not been met. . This condition occurs at the crank or immediately after start before fuel trim has started
2. fuel trim with 2 probes . This situation occurs during driving when both probes are used during fuel trim (part load).
3. no fuel trim, operation with predefined values . This situation occurs during hard acceleration or during fuel shut-off when there is no fuel trim and operation is under predefined values.
4. no fuel trim, operation with system fault . This situation occurs when an earlier diagnostic trouble code (DTC) was stored that caused the fuel trim to be disabled
5. fuel trim with one probe (front) . This situation occurs at idling speed or during light acceleration when one probe (front) is used during fuel trim.

Precautions when replacing control module

Scheme 53

1. Ignition off. Wait for 2 minutes
2. Remove the cover over the control module box. Put the cover to one side. NOTE: Do not touch the control module's pins with your fingers. Static electricity may damage components in the control module.

5. Carefully pull up the control module.

Scheme 54

1. Check that no pins or sockets are damaged on the connector.
2. Gently press the control module down into the grooves inside the control module box. Press to the limit position.
3. Insert tool «9995722»(ref-403953-S10522720692011061000000) around the control module.

6. Check that the air ducts are correctly positioned.

Ordering software

Order software. See

After downloading the software or replacing the engine control module (ECM), the throttle unit must be adapted according to vehicle communication input: "Adapting the throttle unit". Remedy as necessary.
