DTC Detecting Condition Trouble Area
Mismatching solenoid output and solenoid monitor is
detected.
• ESP® control module
Step Action Yes No
1 Was “Electronic Stability Program Check” performed? Go to Step 2. Go to “Electronic
Stability Program
System Check”.
2 Check solenoid valve power supply circuit
1) Turn ignition switch to OFF position.
2) Disconnect ESP® control module connector.
3) Check for proper connection to ESP® control module
connector at terminal “E85-1”, “E85-16” and “E85-47”.
4) If OK, then measure voltage between terminal “E85-1” of
module connector and “E85-16, E85-47”.
Are they 10 – 14 V?
Substitute a known-
good ESP® hydraulic
unit /control module
assembly and recheck.
“WHT/BLU” or “BLK”
circuit open.
