Pinpoint Test Descriptions

Pinpoint tests

CAUTION: When probing connectors to take measurements in the course of the pinpoint tests, use the adaptor kit, part number 350-1358-00.

NOTE: When performing electrical voltage or resistance tests, always use a digital multimeter (DMM) accurate to 3 decimal places, and with an up-to-date calibration certificate. When testing resistance, always take the resistance of the DMM leads into account.

NOTE: Vehicles built before December 2003 have four suspension height sensors which are mounted on the front and rear subframe assemblies, two front and two rear. Vehicles built after December 2003 have only three (the right front sensor being deleted), although the functionality of the system remains the same. There may be some early vehicles which will have four sensors fitted, but which have the three-sensor module, making the right front sensor redundant To confirm the level of equipment read the module part number from the special applications menu in configuration on the Jaguar approved diagnostic system. Part numbers before 'BJ' are four sensor, while 'BJ' and after are three sensor. if the Jaguar approved diagnostic system is not available, remove the rear seat and sound deadening and read the part number from the module.

NOTE: Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.
