THE HOME OF MG-Rover RESCUE
I can repair all problems associated with the MG-Rover Pektron SCU, I can offer full diagnostics and programming including options not available on the dealer T4 tool.
These units have the part numbers YWC001540 and YWC001541 and were fitted to vehicles from 2003 onwards.
I can also repair the 315MHz versions of this unit as fitted to Australian, New Zealand and Japan vehicles, these units have the part numbers YWC001550 and YWC001551.
The most common problem with the SCU is relay failure. This stems from the fact that poor quality relays were used in the original manufacture.
Other common faults are;
Damage by water ingress (Rover 25/Streetwise & MG ZR)
Horn operates constantly.
Indicators flash too quickly.
Indicators and/or Hazards do not operate.
Lack of remote fob transmission range.
Tailgate (boot) release does not work.
Circuit board burn-up caused by tailgate wiring loom faults and
surges caused by jump starting.
Unit does not power up.
This section lists the repair services and spare parts I can supply for the Pektron SCU.
I offer an SCU relay replacement service and can repair any SCU fault.
I also offer a number of parts that can be used for a DIY repair.
Relay failure is the most common fault with the Pektron SCU, I can offer a relay replacement service if you don't want to carry out soldering on the circuit board yourself.
The relays control the following circuits...
Windscreen Washers, front and rear.
Superlocking (Door deadlocking).
Intermittent Front Wiper.
The standard repair consists of replacing all five relays and a full working test of the SCU.
For UK customers the cost is £50 and for EU customers it is £60.
This repair service requires that you send your original faulty SCU module to me for repair.
Repairs are carried out on the same day as received and the EKA Code is retrieved from the SCU memory at no extra cost.
Return delivery in the UK is by Royal Mail 1St Class Recorded or Special Delivery 1pm, this is included in the repair cost.
Return delivery in the EU is by Royal Mail International Signed / Signed & Tracked, this is included in the repair cost.

A quality relay that is a direct replacement for the 0662P04A relay as fitted to the MG-ROVER Pektron SCU and the ESA and ETACS modules as fitted to the LDV Maxus range of vans.
The reliability of this relay is such that I offer a 5 year warranty on this item, over 9000 have been sold to date.
The price for a quantity of 5 relays contains a discount.
The faulty relays must be desoldered from the SCU circuit board and the replacements soldered in place. Please use my Replacement Relay Service if you don't want to have to solder!
To make a purchase please select the quantity required from the drop down menus below, postage is
included in the relay price for UK, EU and Rest Of World customers.
Due to the cost of postage for Rest Of World locations (Australia, New Zealand , Americas etc.) it only makes economic sense to purchase 5 relays.
All prices include postage to your location.
I can offer full fob programming services including the ability to program fobs to SCU modules which have no working fobs and cannot be accessed using standard "on vehicle" diagnostic tools.
I always have new OE fobs in stock, priced at £75 each supplied and programmed.

The TPIC6A595 and TPIC6C595 driver IC's are used in the Pektron SCU to switch on the internal relays and also control external relays and low power circuits.
The TPIC6A595 is used to drive the external indicator relays. When this IC fails it can cause the indicators to remain on.
There are two TPIC6C595 IC's fitted to the board, when one of these IC's fails it keeps the horn
All of the IC's are surface mounted devices, these can be difficult to replace. Please only attempt the
replacement of these IC's if you have the correct equipment and experience.
