SUBJECT:
1983, 1984 ECI SYSTEM VOLTMETER CHECK PROCEDURE
USE OF VOLTMETER TO TEST ECI SYSTEM
The ECI system on 1983 and 1984 Starions and 1984 Turbo Cordia/Tredia models can be checked using a multimeter or any high-impedance voltmeter.
This method is useful when checking the ECI system without unplugging the computer (and consequently erasing the memory) or when the ECI checker
is not available.
Figure 1
VOLTMETER PROBES AND CONNECTIONS
To perform the tests in this bulletin, voltages will be measured right at the computer which is on the right cowl kick panel. Make up a set of thin probes
from stiff wire to attach to your voltmeter and insert into the tops of the connectors on the computer as shown in Figure 1. You don't have to unplug the
connectors, but you may findit convenient to remove the computer from the kick panel to make it easier to reach the connector terminals.
CAUTION: Short-circuiting the positive (+) probe between a connector terminal and ground could damage the vehicle wiring, the sensor, the ECU, or
all three. Use care to prevent this! Insulate the exposed part of the probe with insulating material as a precaution.
