Precautions When Working On ABSNLBR0149+Use recommended tyres in combination with ABS.
+Please fit tyres or studded tyres, etc. with the same size.
+If different sizes of tyres, or tyres other than the ones rec-
ommended for use with the ABS, are fitted, stopping dis-
tance will increase and control and stability could deterio-
rate.
+When changing brake pads, please use Nissan genuine
parts.
+When fitting radios etc, do not position the radio itself,
antenna, or antenna cables within an area of about 100
mm (3.94 in) of the control unit.
+When doing any work that requires electro-welding, first
remove the control unit.
+Please take care when taking a power supply for the
audio, lamps etc., not to take this from any ABS-related
harness. (Please refer to the electrical wiring diagrams for
ABS-related harnesses)
Wiring Diagrams and Trouble DiagnosisNLBR0003When you read wiring diagrams, refer to the following:
+GI-11,“HOW TO READ WIRING DIAGRAMS”
+EL-10,“POWER SUPPLY ROUTING”
When you perform trouble diagnosis, refer to the following:
+GI-32,“HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSIS”
+GI-21,“HOW TO PERFORM EFFICIENT DIAGNOSES FOR AN ELECTRICAL INCIDENT”
