Vehicle Quiescent Current Test
WARNING: This page is about a different car, the 2019 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.
If a customer complains of a startup battery that discharges continuously or when left for a prolonged period of time, it is recommended that a quiescent drain test is done as described below.
When the vehicle is armed, the effect of the security system status indicator flashing is to cause a pulsation in the measured current drain. In this case, either the average current should be taken (using a digital multimeter) with an averaging system) or the current reading taken, ignoring the brief high current peaks.
Equipment
A digital multimeter with current clamp.
