Inspection/Scan Tool Testing and Procedures/Preliminary Check
Start diagnosis
-
Disconnect the Selector Lever Sensor System Control Module J587 electrical harness connector.
Checking voltage
-
Using a Multimeter, check the Selector Lever Sensor System Control Module J587 electrical harness connector terminal 10 to Ground (GND) for
voltage.
-
Switch the ignition off.
Specified value: battery voltage.
If the specified value was not obtained:
-
Check the Selector Lever Sensor System Control Module J587 electrical harness connector terminal 10 to the Battery A the for an open circuit or
short to Ground (GND).
-
Check the wiring connection for damage, corrosion, lose or broken terminals.
-
If necessary, repair the faulty wiring connection.
If the specified value was obtained:
-
Using a Multimeter, check the Selector Lever Sensor System Control Module J587 electrical harness connector terminal 9 to Ground (GND) for
voltage.
Specified value: battery voltage.
If the specified value was not obtained:
-
Check the Selector Lever Sensor System Control Module J587 electrical harness connector terminal 9 to the Generator (GEN) C terminal L for an
open circuit or short to Ground (GND).
-
Check the wiring connection for damage, corrosion, lose or broken terminals.
-
If necessary, repair the faulty wiring connection.
If the wiring and voltage were OK:
-
Using a Multimeter, check the Selector Lever Sensor System Control Module J587 electrical harness connector terminal 5 to Ground (GND) for
voltage.
Specified value: battery voltage.
If the specified value was not obtained:
-
Check the Selector Lever Sensor System Control Module J587 electrical harness connector terminal 5 to the Generator (GEN) C terminal L for an
open circuit or short to Ground (GND).
-
Check the wiring connection for damage, corrosion, lose or broken terminals.
-
If necessary, repair the faulty wiring connection.
If the wiring and voltage were OK:
