Precautions
IAlways use a 12 volt battery as power source.
IDo not attempt to disconnect battery cable while engine is
running.
IBefore connecting or disconnecting the ECM harness
connector, turn ignition switch OFF and disconnect nega-
tive battery terminal. Failure to do so may damage the ECM
because battery voltage is applied to ECM even if ignition
switch is turned off.
IBefore removing parts, turn off ignition switch and then
disconnect battery ground cable.
IDo not disassemble ECM.
IIf 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 prob-
lem. Do not replace parts because of a slight variation.
IWhen ECM is removed for inspection, make sure to ground
the ECM mainframe.
IWhen connecting ECM harness connector, tighten secur-
ing bolt until the gap between the orange indicators disap-
pears.
: 3.0 - 5.0 N×m (0.3 - 0.5 kg-m, 26 - 43 in-lb)
IWhen 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.
ISecurely connect ECM harness connectors.
A poor connection can cause an extremely high (surge)
voltage to develop in the circuit, thus resulting in damage
to ICs.
IKeep ECM harness at least 10 cm (3.9 in) away from adja-
cent harnesses, to prevent an ECM system malfunction

due to receiving external noise, degraded operation of ICs,
etc.
IKeep ECM parts and harnesses dry.
IBefore replacing ECM, perform Terminals and Reference
Value inspection and make sure ECM functions properly.
Refer to EC-69.
IIf MI (MIL) 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.
IAfter performing each TROUBLE DIAGNOSIS, perform
ªDTC Confirmation Procedureº or ªOverall Function
Checkº.
The DTC should not be displayed in the ªDTC Confirmation
Procedureº if the repair is completed. The ªOverall Func-
tion Checkº should be a good result if the repair is com-
pleted.
IWhen 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.
IDo 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-10

IDo not disconnect pump harness connector with engine
running.
IDo not disassemble electronic fuel injection pump.
If NG, take proper action.
IDo not disassemble injection nozzle.
If NG, replace injection nozzle.
IEven a slight leak in the air intake system can cause seri-
ous problems.
IDo not shock or jar the crankshaft position sensor (TDC).
IDo not depress accelerator pedal when starting.
IImmediately after starting, do not rev up engine unneces-
sarily.
IDo not rev up engine just prior to shutdown.
IWhen installing C.B. ham radio or a mobile phone, be sure
to observe the following as it may adversely affect elec-
tronic control systems depending on its installation loca-
tion.
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.
