Jaltest · DTC · EBS

Why diagnose roadside

A lamp, limp or ‘it won’t crank’ is not enough to order parts. Jaltest splits electrics, AdBlue, DPF and mechanical. On a trailer: ISO 7638 / EBS with a PTE tester.

Makes

Mostly DAF and Scania. MAN, Volvo, Mercedes, Iveco and Renault as well — if the interface allows.

Without a workshop visit?
Often yes. That is why Rescue asks for a dash photo.
Diagnostics = repair?
