2) Disconnect ESP® control module connector.
3) Check for proper connection to ESP® control module
connector at terminals "E08-9", "E08-23","E08-24"h,
"E08-25" and "E08-26".
4) If OK, then turn ignition switch to ON position and
measure voltage between terminal "E08-9" and vehicle
body ground.
Is it 10 – 14 V?
3 Pump motor and solenoid valve power supply circuit
1) Turn ignition switch to OFF position.
2) Measure voltage between each terminal of "E08-24",
"E08-25" and vehicle body ground.
Are they 10 – 14 V?
4 Check ESP® hydraulic unit / control module assembly
ground circuit
1) Measure resistance between each terminal of "E08-23",
"E08-26" and vehicle body ground.
Is resistance less than 2
