(1) terminals a pair of applicable sensor terminals is
no continuity (circuit short check)
• Resistance of applicable sensor terminal of ESP®
control module connector and vehicle body ground is
no continuity (ground short check)
• Resistance of applicable sensor terminal of ESP®
control module connector and corresponding terminal
of wheel speed sensor connector (2) in main harness
(for front sensor) or floor harness (for rear sensor) is
continuity (continuity check)
• Voltage of applicable sensor terminal of ESP® control
module connector and vehicle body ground is 0 V with
ignition switch turned ON (power short check)
