Before You Begin Servicing
CAUTION
• Do not plug or unplug the E-ECU for a
period of at least 6 seconds after
power to the unit has been turned on
or off.
• Do not touch connector pins of the E-
ECU with bare hands.
Doing so may result in corrosion of the
connector pins and/or damage to the
internal circuits of the E-ECU due to
static electricity.
• Do not force a measuring probe into
the female coupler.
Doing so may cause contact failure of
the connector pins, resulting in
malfunction of the E-ECU.
• Take care to prevent water from
entering the couplers when plugging
or unplugging the connector.
Water inside the couplers may cause
corrosion, resulting in malfunction of
the E-ECU.
• Avoid plugging/unplugging the
connector more than approx. 10 times.
Frequent plugging/unplugging of the
connector may cause contact failure of
the connector pins, resulting in
malfunction of the E-ECU.
• Do not use the E-ECU that has ever
suffered drop impact.
CAUTION
Always check the battery for proper
charge.
Otherwise the electronically controlled
engines may fail to start.
