- Check can communication system*
- Check for dtc (see page ps-11).
Result 
Hint:
- When any can communication system dtcs are output, perform troubleshooting on the can communication system first.
- When communication to the power steering ecu is not established through the intelligent tester, inspect terminals sil of the dlc3 and the power steering ecu, and the ig circuit of the power steering ecu.
- Check dtc*
- Check for dtc (see page ps-11).

Inspection
Inspect cylinder block for warpage
Using a precision straightedge and feeler gauge,
measure the warpage of the surface that is in
contact with the cylinder head gasket.
Maximum warpage:
0.05 Mm (0.0020 In.)
If the warpage is greater than the maximum, replace
the cylinder block ...
