Programming and Relearning
Reading Off Control Module Identification
The Volvo Scan Tool (ST) identifies control modules by readingt a code from the memory of the module. This code contains the control module P/N and softeare version.
Reading Off And Programming Lock And Alarm Systems
This function can bw used to read off programmed data and program data into the control module. Programming the lock and alarm functions adapts the system to market requirements and equipment levels. To program the system a PIN is required. There are 3 codes per car, one for each function.
Programming Remote Control
As standard two transmitters are programmed. One additional remote control can be programmed without reprogramming the first two transmitters. New remote control can be added by erasing old ones (if a remote control is broken or has been lost). The number of transmitters programmed can also be read off.
Programming Lock Type
Three lock types can be programmed - Standard, Deadlocking and Two-stage locking. The programmed lock type can also be read off.
NOTE: To program deadlocking, the car must have the correct lock unit.
Programming lock and alarm functions
Status: Alarm on/off
Indicates if this function is active - if the car has an alarm.
Status: Ultrasonic sensor on/off Indicates if the ultrasonic sensors are active.
Status: Glass breakage sensor on/off Indicates if the glass breakage sensor is active.
Status: Tilt sensor on/off
Indicates if the tilt sensor is active.
Status: Relocking on/off
Indicates if the automatic relocking function is active.
Status: Automatic activation on/off Indicates if the automatic activation function is active.
Status: Key activation on/off
Indicates if key activation of the alarm is active.
Status: Key deactivation on/off
Indicates if the key deactivation function is active.
Status: Central locking alarm on/off
Indicates if the central locking switch alarm activation function is active
Status: Panic alarm on/off
Indicates if the panic alarm function is active.
Status: Visual acknowledgment signal on arming/disarming on/off
Indicates if the locking/unlocking visual acknowledgment signal function is active.
Status: Automatic activation on/off
Indicates if the automatic activation function is active.
The programmed functions can also be read off.
Reading Off Programming Data
If the VGLA control module needs to be replaced, all data in the old control module must first be read off so that the new control module can be correctly configured. This is carried out with the Volvo Scan Tool (ST) as follows: Select PROGRAMMING and then READ PROG.STAT. The lock and alarm system configuration can now be read off. Read off and note all values. Replace control module according service and repair. Replacing main control module and program in the previously noted values. If the fault in the control module makes it impossible to read off the programmed values, use visual identification to determine how the lock and alarm system is equipped and programmed.
Diagnostics / Programming
The VGLA control module is connected to the diagnostic test point. The control module has diagnostics in accordance with the new concept as well as a number of programmable functions. It is possible to communicate with the VGLA control module using the System Tester. There are four different main menus with sub-menus.
Diagnostic test
Reading error codes - counter - frozen values.
The control module can identify 21 different faults.
The LED is used to indicate system faults for 10 of the error codes. For 7 of these error codes the code must occur 5 times before the fault is indicated via the LED.
Each error code has a counter showing the number of error free cycles since the error occurred.
A cycle = ignition on + speed >5 km/h + ignition off.
Indication via LED is erased after 15 error-free cycles and error codes are erased after 255 error free cycles.
A number of values are frozen (1 or 5 depending on the error code) for each error code.
Reading the reason for the alarm
The control module can store a max of 9 alarm causes in succession, the same cause can recur many times.
Erasing
Error codes can only be erased if all the error codes have been read.
Error codes - counters - frozen values and alarm causes can be erased at the same time.
Activation
A number of output signals from the control module can be activated individually.
(11 functions can be activated)
By watching - listening - measuring it is possible to manually check if the signal reaches its component and if the component works.
Monitor test
Values and status of control module's input and output signals can be read.
(32 different parameters can be read)
Reading the control module identification
The control module's part number (hardware).
Pressing HELP when the part number is shown will also display the number of the program (software).
Programming
Reading programming status
Shows the current programming of the control module.
Programming a new control module
New control modules are delivered with error code 'GLA 113' = the control module has not been programmed. While this error code is set the central locking system, alarm and courtesy light do not work.
After fitting the control module to the car it must be programmed for the actual car, connected components as well as required functions (market dependent).
Access to 3 PIN codes is required to program the control module.
The PIN codes are stored at Volvo's central vehicle register and the codes can be obtained using the same routine as for ordering keys.
PIN code 1 -> required to program codes for approved remote controls.
PIN code 2 -> required to select lock type.
PIN code 3 -> required to activate components and select functions.
Program control module (old control module)
Program codes for remote controls (PIN code 1 is required).
Max 3 codes can be entered.
The alternatives are: add code and erase old codes/add new codes.
Program/select lock type (PIN code 2 is required).
The alternatives are: Normal Two step unlocking - Blocked locking position.
NOTE: For blocked locking position to work the door locks must have the right design.
Program/select components and functions (PIN code 3 is required).
The component choice is partly determined by the type of body selected (4/5-door). The functions that can be selected are partly determined by the market (legal and insurance requirements).
