Hint:
The standard normal voltage between each pair of ecm terminals is shown in the table below. The appropriate conditions for checking each pair of terminals are also indicated. The result of checks should be compared with the standard normal voltage for that pair of terminals, displayed in the specified condition column. The illustration above can be used as a reference to identify the ecm terminal locations.
Hint:
*: The ecm terminal voltage is constant regardless of the output voltage from the sensor.

Engine immobiliser system malfunction
Description
This dtc is output when one of the following occurs: 1) the ecm detects
errors in its own
communications with the transponder key ecu; 2) the ecm detects errors in the
communication lines; or
3) the ecu communication id between the transponder key ecu and ecm is different
an ...
