Circuit - Suzuki Swift Sport 2004 Service & Repair Manual

4E-17 ABS:
Step
5 1) Turn ignition switch to OFF position.
2) Check for proper connection to ABS hydraulic unit /
control module connector at terminals "E03-13" and
"E03-26".
3) If OK, measure resistance between each terminal of
"E03-13", "E03-26" and vehicle body ground.
Are resistance less than 2
6 1) Check if communication is possible by trying
communication with other controller (ECM, BCM or
SDM).
Is it possible to communicate with other controller?
7 1) Turn ignition switch to ON position.
2) Measure voltage between terminal B of data link
connector and vehicle body ground.
Is voltage 10 – 12 V?
8 1) Turn ignition switch to OFF position.
2) Measure resistance between the following terminals;
• Terminal G of data link connector and vehicle body
ground.
• Terminal G1 of data link connector and vehicle body
ground.
Is each resistance 1
9 1) Turn ignition switch to OFF position.
2) Check proper connection at "E03-5" ("PPL/WHT" wire)
terminal for serial data circuit.
3) If OK, then check resistance between "E03-5" ("PPL/
WHT" wire) terminal and "PPL/WHT" wire terminal (2) for
serial data circuit in DLC (1).
