The 10AS control unit was used on Land Rover vehicles, predominantly the Defender and Discovery.
It can be configured as a basic immobiliser (rather insecure!) as on the base Defender but has the capability of being a secure immobiliser, alarm and central locking controller with remote fobs.
It also supports many different immobiliser protocols, EDC, Spider, TD5/MEMS, DDS.
I can repair any fault on this unit and keep all common components in stock.
Typical faults include...
Missing immobiliser data output signal.
No courtesy light operation.
Poor fob range.
Central locking faults.
Board/component damage due to water ingress.
The 10AS module has now been discontinued by Land Rover and is no longer available as a new spare part.
All diagnostic options are available, re-configuring software settings and fob programming.
Please contact me with your requirements.
The 10AS uses a now obsolete Motorola processor, to provide modules for Defender production Land Rover had the module redesigned around a modern processor but retained the same connectors and pinouts. This module was introduced in 2012 and has proven to be troublesome with a distinct lack of support by aftermarket diagnostic tool manufacturers.
This module is easily distinguished as it uses a black plastic case and 10AS is not printed on the white label.
The label will show a part number such as
CH12-15K600-BC or similar.
At this time I do not currently repair this later black cased module.
The 10AS module has many software settings to enable various options and to suit a wide range of engine configurations, it will also memorise up to four remote fobs.
I can carry out all option and fob programming for a fixed charge.
Ths service can also be used if you simply need your unit tested. I will carry out a full functional hardware and software test, a full list of the unit's
configuration will be
supplied in printed form.

I can upgrade the basic version of the 10AS, as fitted to the Defender, so that it can control central locking and has all of the standard alarm features enabled.
The following 10AS part numbers are basic units which DO NOT contain the central locking components;
The upgrade consists of:
Fitting the correct NEC relay.
Fitting the associated components.
Enable full alarm and central locking features.
There is the option to include two fobs fully programmed with the upgrade, ideal for the basic Defender setup where no fobs were originally supplied with the vehicle.
This service requires that you remove and send your 10AS to me for the work to be carried out, the existing immobiliser settings will not be altered. Upon return the unit is simply connected back to the vehicle. I will provide full technical help if you need assistance with wiring central locking components to the 10AS.
