Pinpoint Tests

PINPOINT TEST EM : EMISSION COMPLIANCE

NOTE: Canada and some states or metropolitan areas in the United States require periodic emission, or inspection/maintenance tests. All Ford products are designed to pass these tests. If a Ford product fails the test, the most likely causes are:

The engine or catalyst temperature are not warm and stabilized before the test.
Excessive idling by the vehicle before the test.

Normal Operation and Fault Conditions

If any new emission components are installed, carry out the following steps before repeating the inspection/maintenance test procedure:

Reset the KAM. Refer to Resetting The KAM.
To relearn some basic adaptive learning (trim) values, run the engine at 2,500 RPM for 1 minute and idle the engine for 2 minutes.

Verifying an excessive grams per mile (gpm) indication using a parts per million (ppm) reading.

For excessive vehicle gas readings, compare the actual gpm reading to the gas cutpoint level needed to pass testing. This gives an indication of how much the ppm reading has to be reduced (if the actual reading is twice the cutpoint, the baseline reading has to be cut in half or more).

Example:

The actual HC produced by a vehicle is 1.6 gpm. The cutpoint for HC in this example is 0.8 gpm. The actual reading is twice the cutpoint.
The HC reading obtained for the same vehicle during the baseline drive averages 440 ppm. In order for this vehicle to pass the inspection/maintenance test, the HC reading from the verification trip must be at least half of the baseline reading, or an average of 220 ppm or less.
This method only gives a general idea of how much the ppm reading needs to be reduced in order for the vehicle to pass an inspection/maintenance test that calculates gpm. This test is not exact. Experience still has to be used to determine if the emission readings are reduced enough for the vehicle to pass the inspection/maintenance test.

Normal Operation and Fault Conditions

Refer to the DTC Fault Trigger Conditions.

DTC Fault Trigger Conditions

DTC	Description	Fault Trigger Condition
PCM P0420:00	Catalyst System Efficiency Below Threshold (Bank 1): No Sub Type Information	Sets when PCM detects the bank 1 catalyst system efficiency is below the acceptable threshold. Under normal closed loop fuel conditions, high efficiency catalysts have oxygen storage capability. As catalyst efficiency deteriorates, its ability to store oxygen declines. Refer to the Catalyst Efficiency Monitor description for additional information. Diagnose any base engine concerns. Refer to the appropriate 303-00 section, Engine System.
PCM P0430:00	Catalyst System Efficiency Below Threshold (Bank 2): No Sub Type Information	Sets when PCM detects the bank 2 catalyst system efficiency is below the acceptable threshold. Under normal closed loop fuel conditions, high efficiency catalysts have oxygen storage capability. As catalyst efficiency deteriorates, its ability to store oxygen declines. Refer to the Catalyst Efficiency Monitor description for additional information. Diagnose any base engine concerns. Refer to the appropriate 303-00 section, Engine System.

Emergency Locking

Each door has a backup power system which allows the door to function if your vehicle has no power. The system has a limited number of operations before the power is depleted and turns off. When the system turns off, the door remains open and unlatched and does not close.

If your vehicle has no power and the backup power system is turned off, you can close and secure your vehicle by manually resetting each door latch using a key in the position shown.
