1 Scope

Note: Nothing in this standard supersedes

applicable laws and regulations.

Note: In the event of conflict between the English

and domestic language, the English language shall

take precedence.

1.1 Purpose. To determine the vehicle level

operating range performance of the Remote

Function Actuation (RFA) subsystem in various

operational environments. These include open

range, temperature, humidity, and jamming by on-

board and external sources.

1.2 Foreword. This test procedure is primarily a

performance test that can be used for development

and validation purposes. This procedure is divided

into sections that can be run independently of one

another, depending on performance concerns and

the criteria defined by the GM Component

Technical Specification (CTS) or Subsystem

Technical Specification (SSTS).

1.3 Applicability. This procedure applies to all

vehicles with active Remote Function Actuation

systems. These include but are not limited to RFA,

Remote Keyless Entry (RKE), Remote Start, and

Easy Key active systems. This procedure does not

apply to passive RFA systems.

3.5.2 Determine with the requesting engineer the

sections of 4.2.2 that will be tested and if any

functions other than lock/unlock will need to be

tested for 4.2.2.7 and 4.2.2.9.

3.6 Personnel/Skills. No special skills are

required. Driving privileges at MPG/DPG will be

needed to access those sites.

4 Procedure

4.1 Preparation.

4.1.1 Test Information. Complete the test

information data sheet, Test Information, Appendix

A, Data Sheet A2. Install the RFA receiver and

transmitter to be tested. Verify the location and

orientation of the receiver per instructions provided

by the requesting engineer. If none given, use the

production design intent location and orientation.

4.1.2 Test Setup – Test Pad. Park the test vehicle

on the center dot of the test pad facing the

direction marked zero degrees. Center the vehicle

over the dot (left/right and front/back). The front of

the vehicle is defined as zero degrees and testing

will proceed clockwise around the vehicle.

Program the vehicle, if possible, for audible and

visual RFA activation verification (usually horn

honks and flashing headlamps) to make it easier to

detect an activation. Place the vehicle in Park, turn

ignition off, remove keys/fob, close and lock all

doors as if parked at a shopping center, etc.

Measure the vehicle battery voltage and the fob

battery voltage. Replace the fob battery if

necessary. Complete the rest of the Test Data

Sheet header information.

4.1.3 Test Setup – Turntable. If a turntable is to

be used, refer to ISO Work Instruction EN-6.3-W-

EMCTV0071 or specific setup instructions for the

equipment.

4.1.4 Test Setup – Remote Site. Create an angle

template as shown in Appendix B. Affix the

template to the center of the roof of the vehicle,

with 0 degrees facing front center. Cut an 11 m

length of rope and mark it with tape every 1 m.

Attach one end of the rope to the center of the

template on the roof of the vehicle.

Test with the vehicle parked facing the closest

visible jamming source (antenna tower). Also test

with the vehicle parked facing perpendicular to that

direction.

4.1.5 Holding the Key Fob. Measure 1 m from the

ground to a point along the right side of your body.

This is the height you must hold the fob for the

entire test. Hold the fob in your hand with index

finger curled under fob (current fobs have a groove

on the underside). The fob polarization positions

shown in Figure 1 are the most common.

4.1.5.1 Place your forearm and elbow against your

body, extending your hand so that the fob is 1 m in

height from the ground and 15 cm (6 in) in front of

your body. Press fob buttons with thumb only,

unless multiple buttons need to be pressed

simultaneously.

4.1.5.2 The most common sources of test to test

variation come from how the key fob is held

(height, distance from body, orientation) and

routing of the wire harness to the receiver. Be sure

to keep these factors in control. Do not wear

gloves or jewelry on the hand being used to hold

the fob.

4.2 Conditions.

4.2.1 Environmental Conditions. Testing can be

completed under any ambient temperature as

described in 4.2.2. See the RFA CTS or SSTS for

any limitations.

Allow enough time for the vehicle interior

temperature to come to ambient or test conditions.

Measure and record weather conditions on the

Test Data Sheet.

Unless directed by the requesting engineer, do not

test when there is standing water (rain, snow, ice)

on the test pad. Also do not test when it is actively

raining, snowing, or in dense fog. Test variations in

these conditions have not been thoroughly studied.

4.2.2 Test Conditions. Deviations from the

requirements of this standard shall have been

agreed upon. Such requirements shall be specified

on component drawings, test certificates, reports,

etc.

Validation testing should perform all of the

following conditions unless directed otherwise by

the requesting engineer.

4.2.2.1 Right Hand, Open Range, Normal

Ambient. Baseline RFA range performance with

no outside influences (jamming, temperature,

humidity) using the right hand to activate the fob in

the horizontal position from Figure 1.

4.2.2.2 Left Hand, Open Range, Normal

Ambient. Same as above, using the left hand to

activate the fob.

4.2.2.3 Vertical, Open Range, Normal Ambient.

Test using worst case hand from above using

vertical hand position shown in Figure 1.

4.2.2.4 High Temperature, Open Range. Test

with vehicle interior temperature (at receiver)

 60°C (140°F). Test using worst case hand and

position.

4.2.2.5 Low Temperature, Open Range. Test with

vehicle interior temperature (at receiver)  0°C

(32°F). Test using worst case hand and position.

4.2.2.6 On-Board EMI Jamming, Open Range.

Turn on as many continuously running EMI

sources as possible. See examples in Table 2.

Test using worst case hand and position.

Substitute variable EMI Range for Spec Range in

the instructions. If significant range degradation is

found, turn off noise sources one at a time and

retest to identify the root cause source.

Note 1: Use the highest speed settings unless another speed is

known to be worst case or specified by the requesting engineer.

4.2.2.7 Remote Start, Open Range, Normal

Ambient. Test using the worst case hand and

position from above. Substitute the Remote Start

button function for Unlock and Remote Stop button

function for Lock in the instructions. Substitute

cycle for data point in the instructions. Wait time

is time between a successful Remote Start and

Remote Stop function. Contact requesting

engineer for button press sequence and time delay

requirements to perform Remote Start and Remote

Stop functions.
