• Is the TRNTEMP PID approximately equal to the motor
temperature?
4-12 CHECK TIM
• Measure the resistance between the motor temperature ports on the
Electric Motor/Transaxle Test Box, determine the motor temperature, and
compare the temperature to the TRNTEMP PID from test step 4-11.
• Is the TIMTEMP PID approximately equal to the motor
temperature?
4-13 VERIFY THE MEASURED RESISTANCE/TEMPERATURE IS IN
RANGE
• Note the measured resistance in test step 4-13.
• Is the resistance within the range indicated in the list in test step
4-12?
Powertrain Diagnostic Routines Identification
TEST STEP ACTION TO TAKE
Yes = REPLACE the TIM. REFER
to Section 303-14.
No = GO to 4-13.
Yes = REPLACE the TIM. REFER
to Section 303-14.
No = REPLACE the
motor/transaxle. REFER to
Section 303-01.
