Toyota RAV4 Service Manual: Starter relay circuit high
Description
While the engine is being cranked, the positive battery voltage is applied to
terminal sta of the ecm. If
the ecm detects the starter control (sta) signal while the vehicle is being
driven, it determines that there
is a malfunction in the sta circuit. The ecm then illuminates the mil and sets
the dtc.
This monitor runs when the vehicle is driven at 20 km/h (12.4 Mph) for over 20
seconds.

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 ...
