Service Bulletin 14: Parking Brake Connector/Wire Failure
Type: Service Bulletin
Affected Models: All Models From FEB 2020 until JUNE 12, 2020.
Model year 2020 (L) delivered from February to June 2020.
Garia has discovered a potential failure where the cable for the brake unit connector can fail. This can cause the parking brake to engage, resulting in stuttering or a sudden stop of the vehicle.
On some vehicles the wiring loom that contains the connector for the electric parking brake can be fixed too tight to ensure enough clearance for the movement of the motor when driving the vehicle at higher speeds on bumpy surfaces. Over time, this can potentially cause the wire/connector for the parking brake to fail.
To prevent unwanted engagement of the parking brake, we recommend to check that the wiring harness is fixed as close to the right hand crossmember as possible, ensuring enough space to clear the motor. Please refer to example below.
Please also verify that there is enough slack in the wire for the parking brake, so that full movement of the rear beam and engine is possible without stressing the wires.
Locate the electric parking brake installed at the end of the motor and follow the two wires to the connector assembly. Disconnect the parking brake connector by pressing the tap on located the plug on the vehicle harness.
Inspect the insulation of the wires for visible damages. Hold the the parking brake plug firmly and give the two wires a solid pull one after the other to ensure that they still are firmly connected to the connector pins in the plug.
When the wiring harness is correctly fixed and if the wires doesn't come loose, your vehicle will not be affected by the issue. You can reconnect the parking brake plug again.
If the wires have physical signs of damage, or they detaches from the plug housing, we recommend that the complete parking brake unit is replaced the ensure trouble-free operation of the vehicle. Please contact us at firstname.lastname@example.org with VIN-number of the affected vehicle so that we can supply you with a replacement parking brake unit.
The spare parts required for this repair must be ordered directly from Garia.
When ordering, present the VIN of the vehicle, Garia will then ship part free of charge.
