Toronado V6-231 3.8L (1986)
Test Description:
The following numbered steps correspond with the step numbers on the diagnostic chart.
8.
Verifies ignition feed voltage at terminal "M" of the C(3)I modules. Less than battery voltage would be an indication of a CKT 639 fault.
9.
The test light to 12 volts simulates a reference signal to the ECM which will result in an injector test light blink if the CKT 430, the ECM and the
injector driver circuit are all OK.
10.
If the Cam Sensor signal circuit terminal "A" is jumpered to the ground circuit terminal "B", the response will be an injector test light blink. This
is a result of this artificial "Cam Signal" being transmitted through the C(3)I module to ECM terminal "A11" and the ECM activating the injection
driver circuit.
11.
Verifies a proper Cam signal circuit voltage of 7 to 9 volts and a good ground from the C(3)I module to terminal "B" of the sensor connector.
12.
Determines if reason for incorrect voltage reading was due to a fault in CKT 633, an open in CKT 632 or a faulty C(3)I module.
