Check ESP® control module power supply circuit
1) Turn ignition switch to OFF position.
2) Check for proper connection to ESP® control module
connector at terminals "E85-1" and "E85-32".
3) If OK, then turn ignition switch to ON position and
measure voltage between each terminal of "E85-1",
"E85-32" and vehicle body ground.
Are they 10 – 14 V?
5
Check ESP® control module ground circuit
1) Turn ignition switch to OFF and measure resistance
between each terminal of "E85-16", "E85-47" and vehicle
body ground.
Is resistance less than 2
6
CAN communication circuit check
1) Check CAN communication circuit between combination
meter and ESP® control module referring to "DTC
