How to Troubleshoot EPS OTCs
The troubleshooting flowchart procedures assume that
the cause of the problem is still present and the EPS
indicator is still on. Following the flowchart when the
EPS indicator does not come on can result in incorrect
diagnosis.
The connector illustrations show the female terminal
connectors with a single outline and the male terminal
connectors with a double outline.
1. Question the customer about the conditions when
the problem occured, and try to reproduce the
same conditions for troubleshooting. Find out
when the EPS indicator came on, such as while
turning,
after turning,
when the vehicle was at a
certain speed, etc.
2. When the EPS indicator does not come on during
the test drive, but troubleshooting is done based on
the
OTe,
check for loose connectors, poor terminal
contact, etc in the affected circuit, before you start
troubleshooting.
3. After troubleshooting, clear the DTC and test-drive
the vehicle. Be sure the EPS indicator does not
come on.
