TROUBLESHOOTING [LA4A-EL]
STEP
INSPECTION
ACTION
F2
CHECK CONTINUITY OF TSS HARNESS
CIRCUIT
• Key off.
Caution
•
Do not pry on connector. Pull up on
harness.
• Disconnect TSS connector.
• Disconnect PCM. Inspect for damaged or
pushed out pins, corrosion, loose wires, etc.
• Install breakout box, leave PCM disconnected.
• Refer to connector schematic of TSS.

TSS Switch Connector Component
• Measure resistance between PCM test pin 84
at the breakout box and the TSS (+) circuit at
the TSS connector.
• Measure resistance between PCM test pin 91
at the breakout box and the TSS (-) circuit at
the TSS connector and chassis/battery ground.
• Is each resistance less than 5.0 ohms?
Yes
Go to next step.
No
Service open circuit.
Remove breakout box.
Reconnect all components.
Rerun OBD test.
F3
CHECK TSS CIRCUIT FOR SHORT TO POWER
AND GROUND
• Key off.
• Disconnect TSS connector.
• Breakout box installed, PCM disconnected.
• Measure resistance between PCM test pins
84, 91 and test pins 71/97 at breakout box.
• Measure resistance between PCM test pins
84, 91, 71/97 and test pins 77/103 at breakout
box.
• Is each resistance greater than 10,000 ohms?
Yes
Go to next step.
No
Service short circuit.
Remove breakout box.
Reconnect all components.
Rerun OBD test.
F4
TSS FUNCTIONAL TEST
Caution
•
Do not pry on connector. Pull up on
harness.
• Disconnect vehicle harness at TSS.
• Install transaxle tester on to TSS.
• Connect voltmeter positive lead to (+) TSS and
negative lead to (-) TSS jacks. Set voltmeter to
20 volts AC.
• Perform drive cycle test. Monitor voltmeter.
• Does the voltage increase with an increase in
vehicle speed?
Yes
Replace PCM.
No
Go to next step.
F5
CHECK RESISTANCE OF TSS
Note
• Refer to the LA4A-EL Transaxle tester for
terminal locations.
• Connect ohmmeter negative lead to +TSS jack
and positive lead to -T S S jack on tester. This
is to test TSS.
•
Record resistance.
• Is the resistance between 140— 290 ohms?
Yes
Go to next step.
No
Replace TSS.
Rerun TSS functional test.
