Fault Trigger Conditions
B1108:77
Driver door central locking motor: Set position not available
Sets continuously when the BCM detects an incorrect feedback on the door lock/unlock monitor circuit after a central lock or unlock event. When the BCM commands the doors to lock, it expects the lock/unlock monitor circuit to be open. When the BCM commands all doors to unlock, it expects the lock/unlock monitor circuit to be grounded.

RKE transmitter has poor range
Normal Operation and Fault Symptoms
Refer to: Door Handles, Locks, Latches and Entry Systems - System Operation and Component Description (501-14 Door Handles, Locks, Latches and Entry Systems, Description and Operation).
For vehicles without push button start, the integrated key head transmitter (IKT) sends a radio signal to the internal antenna of the BCM. If the BCM detects that the signal comes from a programmed integrated key head transmitter (IKT), it then performs 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 key sends a radio signal to the Radio Frequency (RF) receiver. The RF receiver sends passive key information to the RFA module over the communication circuit. If the RFA module (BCM) detects that the signal is from a programmed passive key, it performs 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
Television/radio transmitting towers
Radio Frequency (RF) receiver (vehicles with Push Button Start)
BCM (vehicles without Push Button Start)
Visual Inspection and Preliminary Diagnosis
Inspect the key for damage.
Inspect the key battery.
Inspect for aftermarket RKE systems.
PINPOINT TEST Q: RKE (REMOTE KEYLESS ENTRY) TRANSMITTER HAS POOR RANGE PERFORMANCE
NOTE: At least 2 programmed keys must be present to begin RKE system diagnosis.
NOTE: Aftermarket or dealer-installed systems may adversely affect RKE system operation. Disconnect these systems before diagnosing any RKE system concern.
Q1 CHECK THAT THE KEYS ARE CORRECT
Make sure at least 2 keys of the correct type for the vehicle are available.
Are the correct keys present?
Yes
GO to Q2
No
The system cannot be tested without the correct keys. INFORM the customer that the correct keys must be present to continue with system diagnosis.
Q2 CHECK ALL KEYS FOR POOR RANGE PERFORMANCE
NOTE: The 20 m (66 ft) range measurement is not a standard, but a guideline that clearly indicates normal range performance of the vehicle. Check all keys for normal range (less than 20 m (65.62 ft)).
Do all keys have poor range?
Yes
GO to Q4
No
GO to Q3
Q3 CHECK THE KEY BATTERY
Open the key.
Make sure the correct battery (CR2032) is being used.
Remove the key battery and measure the voltage.
Is the voltage greater than 2.5 volts?
Yes
For vehicles without Push Button Start, REPLACE the suspect key. PROGRAM the PATS key transponder. REFER to: Key Programming with Diagnostic Equipment (419-01B Passive Anti-Theft System (PATS) - Vehicles Without: Keyless Entry and Push Button Start, General Procedures). PROGRAM the RKE transmitter portion of the key. REFER to: Remote Keyless Entry (RKE) Transmitter Programming (501-14 Handles, Locks, Latches and Entry Systems, General Procedures). For vehicles equipped with Push Button Start, REPLACE the suspect key. PROGRAM the key. REFER to: Key Programming with 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 discharged batteries do not erase keys from memory).
Q4 CHECK VEHICLE LOCATION AND APPROACH ANGLES AROUND THE VEHICLE
Confirm that the poor performance is consistent in nature and not related to a single approach angle.
RKE transmitter range may be reduced in certain locations. For example, if the vehicle is within 0.8 km (0.5 mile) of a high-power device or radio/TV tower, the operating range of the keys may be reduced.
Is the poor range consistent around the vehicle?
Yes
For vehicles without 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 currently operating correctly. Range may have been affected by environmental interference such as high-power devices or radio/TV towers.
Q5 CHECK BCM (BODY CONTROL MODULE) OPERATION
Disconnect and inspect all BCM connectors.
Repair:
corrosion (install new connectors or terminals - clean the module contacts)
damaged or bent pins - install new terminal pins
pushed-out pins - install new pins as necessary
Reconnect the BCM connectors and make sure they are fully seated and locked.
Operate the system and determine if the concern is still present.
Is the concern still present?
Yes
CHECK OASIS for any applicable technical service bulletins (TSBs). If a TSB exists for this concern, STOP this test and FOLLOW the TSB instructions. If no TSBs apply to this concern, INSTALL a new BCM. REFER TO: Body Control Module (BCM) (419-10 Multifunction Electronic Modules, Removal and Installation).
No
The system is currently operating correctly. The concern may have been caused by module connections. ADDRESS the root cause of any connector or terminal issues.
