Section 04 ENGINE MANAGEMENT (SDI)
Subsection 03 (COMPONENT INSPECTION, REPLACEMENT AND ADJUSTMENT)
To perform verifications, a good quality multimeter
such as Fluke 111 (P/N 529 035 868) should be
used.
Pay particular attention to ensure that terminals
are not out of their connectors or out of shape.
The troubleshooting procedures cover problems
not resulting from one of these causes.
CAUTION: Ensure all terminals are properly
crimped on wires and connector housings are
properly fastened.
Before replacing an ECM, always check electrical
connections. Make sure that they are very tight
and they make good contact and that they are
corrosion-free. Check if wiring harness shows any
signs of scoring. Particularly check ECM ground
connections. Ensure that contacts are good and
clean. A “defective module” could possibly be
repaired simply by unplugging and replugging the
ECM. The voltage and current might be too weak
to go through dirty wire terminals. Check careful-
ly if terminals show signs of moisture, corrosion
or if they look dull. Clean terminals properly and
then coat them prior to assembling as follows:
If the newly replaced ECM works, try the old one
and recheck if it works.
Ensure that all electronic components are genuine
– any modification on the wiring harness may lead
to generate fault codes or bad operation.
NOTE: For diagnostics purposes, use Vehicle
Communication Kit (VCK). See DIAGNOSTIC
PROCEDURES for proper connectors/adaptors.
After a problem has been solved, ensure to clear
the fault(s) in the ECM using the VCK. Refer to
DIAGNOSTIC PROCEDURES subsection.
Resistance Measurement
When measuring the resistance with an ohmme-
ter, all values are given for a temperature of 20°C
(68°F). The resistance value of a resistance varies
with the temperature. Do not touch the sensor
itself. It may cause wrong result during measure-
ment, because of body heat.
The resistance value for usual resistor or windings
(such as injectors)
increases as the temperature
increases. However, some of our temperature
sensors are NTC types (Negative Temperature Co-
efficient) and work the opposite which means that
the resistance value
decreases as the tempera-
ture increases. Take it into account when mea-
suring at temperatures different from 20°C (68°F).
Use this table for resistance variation relative to
temperature for
temperature sensors.
