Pinpoint Tests

CAUTION: When probing connectors to take measurements in the course of the pinpoint

tests, use the adaptor kit, part number 3548-1358-00.

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:

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

PINPOINT TEST G307559p1 : C1095;
PUMP MOTOR FAULT

G307559t1 : CHECK THE BATTERY POWER SUPPLY (1) TO THE ABS/DSC
MODULE

1. Turn the ignition switch to the OFF position. 2. Disconnect the ABS/DSC module electrical

connector EC30. 3. Measure the voltage between EC30, pin 01 (NR) and GROUND.

•

Is the voltage less than 10 volts?

-> Yes

REPAIR the circuit. This circuit includes the engine compartment fuse box (fuse 20). For additional

information, refer to the wiring diagrams. CLEAR the DTC. TEST the system for normal operation.

-> No
