DTC Troubleshooting
Step
1 Was "Electronic Stability Program Check" performed?
2 Check ESP® control module 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 "E85-32".
4) If OK, then measure voltage between terminal "E85-32"
of module connector and body ground.
Is it 10 – 14 V?
3 Check ESP® control module ground circuit
1) Measure resistance between terminal "E85-16" and
"E85-47" ESP® control module connector and vehicle
