Suzie errors leave trailers unbraked

• Braking and suspension systems manufacturer Wabco Automotive UK has warned vehicle operators to be particularly careful with suzie cables on vehicles fitted with electronic braking systems (EBS).
The firm says the right air and electrical connections are particularly important with EBS-equipped vehicles because EBS has to be powered continuously in order to work.
Wabco cites a fatal accident last December in which a truck driver died when his cab was struck by the swinging trailer of an oncoming artic. An investigation revealed that the artic driver had not connected the ISO 7638 cable, effectively disabling the trailer's EBS/ABS system.
No one knows how widespread this problem is, but Wabco marketing manager Arthur Waddell points out that the accident in December is "already one too many". He adds: "People are just not aware... these are wonderful systems that look after people, but they're not fully automatic—they still need to be switched on."
A Vehicle Inspectorate spokeswoman confirms that the ISO 7638 connection was a factor in the accident.
"We are aware of the serious nature regarding these connections and our staff are being trained to fully understand the implications and operations of these systems," she says. We foresee an increase in enforcement activity for non-use of ISO 7638 connections."
The VI is updating its booklet on ABS/EBS systems; in the meantime its spokeswoman says: 'Check the vehicle properly before embarking on a journey." Wabco has produced a conspicuous free warning label to remind drivers.
