Does vehicle enter PID/Data Monitor and Record?
Yes
REMAIN in PID/Data. GO to E2 .
No
REPEAT procedure to ENTER PID. If vehicle did not enter PID, REFER to thePowertrain
Control/Emissions Diagnosis (PC/ED) manual for diagnosis of PCM or NGS.
E2 DRIVE CYCLE TEST
While monitoring the appropriate sensor PID, drive the vehicle so that the transmission
upshifts and downshifts through all gears.
Does the TSS or OSS Speed PID increase and decrease with engine and vehicle
speed?
Yes
GO to E3.
No
If the TSS or OSS Speed PID does not increase and decrease with engine and vehicle speed,
INSPECT for open or short in vehicle harness, sensor, a PCM concern, or internal hardware
concern. GO to E4 .
E3 DRIVE CYCLE TEST ERRATIC
While monitoring the appropriate sensor PID, drive the vehicle so that the transmission
upshifts and downshifts through all gears.
Is the TSS, ISS, or OSS Speed PID signal erratic (drop to zero or near zero and return
to normal operation)?
Yes
If the sensor signal is erratic, INSPECT for intermittent concern in the harness, sensor, or
connector. GO to E4 .
No
CLEAR all DTCs. RERUN OBD test.
E4 CHECK PCM HARNESS CIRCUITS FOR OPENS
PCM
Inspect for damaged or pushed out pins, corrosion or loose wires.
Install the EEC V Control System Breakout Box.
For OSS, measure the resistance between pin 91 at the EEC V Control System Breakout Box
and the appropriate sensor connector pin 2 harness side.
For TSS, measure the resistance between pin 91 at the EEC V Control System Breakout Box
and the appropriate sensor connector pin 2 harness side.
For TSS, measure the resistance between pin 59 at the EEC V Control System Breakout Box
