Detailed Description

Standard Ignition ALH203 is built as a replacement antilock brake speed sensor harness for the rear left wheel position. It is specified with one female oval connector and four terminals, using male and female terminal interfaces with wire-lead and blade terminal types. This configuration is intended to restore the electrical path between the ABS wheel speed sensor and the vehicle harness on the listed Volkswagen Beetle and Volkswagen Jetta models.

This part cross-references 1P3720 and 5C0927904A for the same application. Use ALH203 when servicing a damaged or intermittent rear left ABS sensor lead on a Volkswagen Beetle or Volkswagen Jetta with the matching equipment notes.

What It Helps Address

• ABS warning light caused by a damaged rear left sensor harness
• Intermittent wheel speed signal from broken wiring or connector wear
• Corrosion at the sensor connection point
• Open circuit or poor continuity in the rear wheel speed sensor lead
• Harness damage from road debris, moisture, or age-related cracking

Installation Notes and Tips

Verify connector shape, terminal style, and rear left position before installation. Inspect the mating ABS sensor connector and surrounding wiring for corrosion, bent terminals, or insulation damage. Confirm vehicle equipment notes: 2019, 2017, and 2015 Volkswagen Beetle, rear left, w/o HID Headlights; 2012-2013 Volkswagen Beetle, rear left, w/o HID Headlights; and 2013 Volkswagen Jetta, rear left, w/o Automatic Headlight Range Control.

After installation, clear any stored ABS fault codes and road test the vehicle to confirm the wheel speed signal is restored.

Quality Assurance

Standard Ignition is a recognized aftermarket brand for electrical and ignition components. ALH203 is listed with direct interchange references and confirmed vehicle fitment for the specified Volkswagen Beetle and Volkswagen Jetta applications.
