1. Turn the ignition switch to ON (II).
2. Clear the DTC with the HDS.
3. Turn the ignition switch to LOCK (0).
4. Turn the ignition switch to ON (II).
Go to step 5.
Check for loose terminals or poor connections.
If the connections are good, the system is OK at
this time.
5. Start the engine.
6. Wait 10 seconds or more.
7. Check for DTCs with the HDS.
Check for loose terminals in the EPS control
unit connectors, and repair if necessary. If no poor
connections are found, replace the EPS control unit
(see page 17-84).
Troubleshoot the indicated DTC. If there are
no DTCs, the system is OK at this time. 1. Turn the ignition switch to LOCK (0).
2. Connect the HDS to the data link connector (DLC).
3. Turn the ignition switch to ON (II).
4. Check the ADVT1 in the DATA LIST with the HDS.
Go to step 5.
Go to step 6.
5. Check the ADVT2 in the DATA LIST with the HDS.
Check for loose terminals or poor
connections. If the connections are good, the
system is OK at this time.
Go to step 6.
6. Turn the ignition switch to LOCK (0).
