Inspection
Step
1 1) Turn ignition switch to ON position.
®
Does ESP warning light come ON?
2 1) Turn ignition switch to OFF position.
Are the condition of the fuses concerning pump motor and
solenoid valves good?
3 1) Disconnect ESP® control module connector.
2) Check for proper connection to ESP® control module
connector at terminal "E53-35".
3) If OK then turn ignition switch to ON position and
measure voltage between terminal "E53-35" and vehicle
body ground.
Is it 10 – 14 V?
4 1) Turn ignition switch to OFF position.
2) Check for proper connection to ESP® control module
connector at terminals "E53-1" and "E53-32".
3) If OK then turn ignition switch to ON position and
measure voltage between each terminal of "E53-1",
"E53-32" and vehicle body ground.
Are they 10 – 14 V?
5 1) Turn ignition switch to OFF position.
2) Check for proper connection to ESP® control module
connector at terminals "E53-16" and "E53-47".
3) If OK, measure resistance between each terminal of
"E53-16", "E53-47" and vehicle body ground.
Are resistance less than 2
