[Precaution after replacing ECM / PCM or Immobilizer Control Mod-
ule]

When ECM / PCM was replaced, including when replaced be-
cause rechecking by using a known-good ECM / PCM was neces-
sary during trouble diagnosis, the ECM/Immobilizer Control Mod-
ule code must be registered in ECM / PCM and Immobilizer
Control Module by performing procedure described in ªProce-
dure after ECM / PCM Replacementº on p. 8G-27. If it is not regis-
tered, the engine would not start and accurate trouble diagnosis
would not be assured.

replaced because rechecking by using a known-good Immobiliz-
er Control Module was necessary during trouble diagnosis, the
Transponder code and ECM/Immobilizer Control Module code
must be registered in Immobilizer Control Module and ECM/Im-
mobilizer Control Module code in ECM / PCM by performing pro-
cedure described in ªProcedure after Immobilizer Control Module
Replacementº on p. 8G-26. If they are not registered, the engine
would not start and accurate trouble diagnosis would not be as-
sured.
