Precautions
+Always use a 12 volt battery as power source.
+Do not attempt to disconnect battery cable while engine
is running.
+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.
+Before removing parts, turn off ignition switch and then
disconnect battery ground cable.
+Do not disassemble ECM.
+If a battery terminal is disconnected, the memory will
return to the ECM value.
The ECM will now start to self-control at its initial value.
Engine operation can vary slightly when the terminal is
disconnected. However, this is not an indication of a
problem. Do not replace parts because of a slight varia-
tion.
+When ECM is removed for inspection, make sure to
ground the ECM mainframe.
+When connecting ECM harness connector, tighten
securing bolt until the gap between the orange indica-
tors disappears.
: 3.0 - 5.0 Nzm (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.
+Securely connect ECM harness connectors.
A poor connection can cause an extremely high (surge)
voltage to develop in the circuit, thus resulting in dam-
age to ICs.
+Keep ECM harness at least 10 cm (3.9 in) away from
adjacent harnesses, to prevent an ECM system malfunc-

tion due to receiving external noise, degraded operation
of ICs, etc.
+Keep ECM parts and harnesses dry.
+Before replacing ECM, perform Terminals and Reference
Value inspection and make sure ECM functions properly.
Refer to EC-1068.
+If MI illuminates or blinks irregularly when engine is
running, water may have accumulated in fuel filter. Drain
water from fuel filter. If this does not correct the problem,
perform specified trouble diagnostic procedures.
+After performing each TROUBLE DIAGNOSIS, perform
ªDTC Confirmation Procedureº or ªOverall Function
Checkº.
The DTC should not be displayed in the ª DTC Confirma-
tion Procedureº if the repair is completed. The ªOverall
Function Checkº should be a good result if the repair is
completed.
+When measuring ECM signals with a circuit tester, never
allow the two tester probes to contact.
Accidental contact of probes will cause a short circuit
and damage the ECM power transistor.
+Do not use ECM ground terminals when measuring
input/output voltage. Doing so may result in damage to
the ECM's transistor. Use a ground other than ECM
terminals, such as the ground.

PRECAUTIONSZD30DDTi
Precautions (Cont'd)
EC-1009

+Do not disconnect pump harness connector with engine
running.
+Do not disassemble electronic fuel injection pump.
If NG, take proper action.
+Do not disassemble injection nozzle.
If NG, replace injection nozzle.
+Even a slight leak in the air intake system can cause
serious problems.
+Do not shock or jar the crankshaft position sensor
(TDC).
+Do not depress accelerator pedal when starting.
+Immediately after starting, do not rev up engine unnec-
essarily.
+Do not rev up engine just prior to shutdown.
+When installing C.B. ham radio or a mobile phone, be
sure to observe the following as it may adversely affect
electronic control systems depending on its installation
location.
1) Keep the antenna as far as possible away from the ECM.
2) Keep the antenna feeder line more than 20 cm (7.9 in)
away from the harness of electronic controls.
Do not let them run parallel for a long distance.
3) Adjust the antenna and feeder line so that the standing-
wave ratio can be kept smaller.
4) Be sure to ground the radio to vehicle body.
