Verify the GEM PID CLTCHSW displays ACTIVE.
Verify that the GEM PID CLTCHSW indicates notACT when the transmission is in any position
other than NEUTRAL or PARK.
Do the GEM PIDs display correctly?
Yes
GO to
B24
.
No
DIAGNOSE the starter interrupt circuit and digital TR sensor; REFER to
Section 303-06
. If the
circuits are OK, REPLACE the GEM; REFER to
Section 419-10
. CLEAR the DTCs. TEST the
system for normal operation.
B24
CHECK THE DIGITAL TR SENSOR — MONITOR THE GEM PID NTRL_SW
Monitor the GEM PID NTRL_SW.
Verify the GEM PID NTRL_SW displays NTRL.
Verify the GEM PID NTRL_SW displays notNTRL when the transmission is in any position
other than NEUTRAL.
Do the GEM PIDs indicate correctly?
Yes
GO to
B28
.
No
GO to
B25
.
B25
CHECK THE GROUND TO THE DIGITAL TRANSMISSION RANGE (DTR) SENSOR
Digital TR Sensor C182
Measure the resistance between digital TR sensor C182-7, circuit 57 (BK), and ground.
Is the resistance less than 5 ohms?
Yes
GO to
B26
.
No
REPAIR circuit 57 (BK). CLEAR the DTCs. TEST the system for normal operation.
B26
CHECK THE DIGITAL TR SENSOR — MONITOR THE GEM PID NTRL_SW
Monitor the GEM PID NTRL_SW.
