Special tools, testers and auxiliary items required
‹› Crimping Pliers (VAS 1978/1 A)
‹› Exchange Head, 0.35mm - 2.5mm (VAS 1978/1-1)
When repairing wires with a cross-section up to 0.35 mm2, new contacts must always be crimped on using Crimping Pliers of JPT Contacts (VAS
1978/9A), or Crimping Pliers (Base Tool) (VAS 1978/1-2) with Head Adapter for JPT Contacts (VAS 1978/9-1) installed. Due to the low current
strengths of these wires in the micro- to milli- range, contacts crimped on incorrectly lead to continuity resistances and cause malfunctions or failure of
the respective system. The most frequent applications of these contacts are:
‹› Heated oxygen sensor (HO2S)
‹› Speed (RPM) sensor
‹› Mass Air Flow (MAF) Sensor
By using (VAS 1978/9A) or (VAS 1978/1-2) with (VAS 1978/9-1) installed, correct connection between crimp contact, wire and single wire seal is
guaranteed. The tool is to be used only for the purpose described.
‹› Contacts in a normal and a gold-plated version are crimped onto repair wires. The same version of the contact that was installed at the factory must
always be used for repairs.
