Engine Control Module: Service Precautions
PRECAUTIONS
Before connecting or disconnecting the ECM harness connector, turn ignition switch OFF and disconnect negative battery terminal. Failure to do so
may damage the ECM because battery voltage is applied to ECM even if ignition switch is turned off.
When connecting ECM harness connector, tighten securing bolt until the gap between orange indicators disappears.
Torque: 3.0 - 5.0 N.m (0.3 - 0.5 kg-m, 26 - 43 in-lb)
When connecting or disconnecting pin connectors into or from ECM, take care not to damage pin terminals (bend or break).
Make sure that there are not any bends or breaks on ECM pin terminal, when connecting pin connectors.
Before replacing ECM, perform Terminals and Reference Value inspection and make sure ECM functions properly.
