The RKE Transmitter Has Poor Range Performance

Normal Operations and Fault Conditions

REFER to: Handles, Locks, Latches and Entry Systems - System Operation and Component Description (501-14 Handles, Locks, Latches and Entry Systems, Description and Operation).

For vehicles without push-button start, the Integrated Keyhead Transmitter (IKT) sends a radio signal to the BCM internal antenna. If the BCM detects the signal is from a programmed Integrated Keyhead Transmitter (IKT), it then carries out the selected action. The RKE radio signal has a normal operating range of 20 m (66 ft).

For vehicles with push-button start, the passive sends a radio signal to the Radio Frequency (RF) receiver. The Radio Frequency (RF) receiver sends the passive key information to the RFA module over a communication circuit. If the RFA module BCM detects the signal is from a programmed passive key, it then carries out the selected action. The RKE radio signal has a normal operating range of 20 m (66 ft).

Possible Causes

Key
Key battery
Aftermarket system
High power devices
TV/radio transmission towers
Radio Frequency (RF) receiver (vehicles with push-button start)
BCM (vehicles without push-button start)

Visual Inspection and Diagnostic Pre-checks

Inspect the key for damage.
Inspect the key battery.
Inspect for aftermarket RKE systems.

PINPOINT TEST Q: THE RKE (REMOTE KEYLESS ENTRY) TRANSMITTER HAS POOR RANGE PERFORMANCE

NOTE: At least 2 programmed keys must be present to begin diagnosis of the RKE system.

NOTE: Aftermarket or dealer-installed systems may adversely affect the RKE system operation. Disconnect these systems before diagnosing any RKE system concerns.

Q1 CHECK FOR THE CORRECT KEYS

Verify at least 2 keys of the correct type for the vehicle are present.

Are the correct keys present?

Yes

GO to Q2

No	The system cannot be tested without the correct keys. INFORM the customer the correct keys must be present to proceed with diagnosis of the system.

Q2 CHECK ALL KEYS FOR POOR RANGE PERFORMANCE

NOTE: The 20m (66 ft) measurement of range is not the standard but a guideline that clearly indicates a vehicle is experiencing normal range performance. Check all keys for normal range performance (less than 20m (65.62 ft).

Do all keys experience poor range?

Yes

GO to Q4

GO to Q3

Q3 CHECK THE KEY BATTERY

Open the key.

Verify the correct battery is used (CR2032).

REFER to: Key Programming Using Diagnostic Equipment (419-01C Passive Anti-Theft System (PATS) - Vehicles With: Keyless Entry and Push Button Start, General Procedures).

No	INSTALL a new battery (make sure the battery is seated correctly). DO NOT reprogram the key (weak or dead batteries do not erase keys from memory).

Q4 CHECK THE LOCATION OF THE VEHICLE AND THE APPROACH ANGLES AROUND THE VEHICLE

Make sure the poor performance is consistent in nature and is not from one approaching angle.

The RKE transmitter range performance may be degraded in certain locations. For example, if the vehicle is within range (0.8 km (0.5 mile) of high-power devices or radio/TV towers, the operating distance of the keys may be reduced.

Is the poor range performance consistent around the vehicle?

Yes

For vehicles not equipped with push-button start, GO to Q5
For vehicles equipped with push-button start, INSTALL a new Radio Frequency (RF) receiver.
REFER to: Radio Frequency (RF) Receiver (501-14 Handles, Locks, Latches and Entry Systems, Removal and Installation).

No	The system is operating correctly at this time. The range may have been affected by environmental interference such as high-power devices or radio/TV towers.

Q5 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION

Disconnect and inspect all the BCM connectors.

Repair:
- corrosion (install new connectors or terminals - clean module pins)
- damaged or bent pins - install new terminals pins
- pushed-out pins - install new pins as necessary

Reconnect the BCM connectors and make sure they seat and latch correctly.

Operate the system and determine if the concern is still present.

Is the concern still present?

Yes

No	The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
