(c)
Position windshield wiper switch to "O" (para 2-4).
(d)
Position master power switch to off (para 2-27f).
Step 3. Check to see if WTEC II Transmission ECU Pushbutton Shift Selector (TEPSS) or WTEC III
Transmission Pushbutton Shift Selector (TPSS) is neutral (N).
(a)
Position master power switch to on (para 2-17a or b).
If WTEC II TEPSS or WTEC III TPSS is blank, perform Transmission Troubleshooting (f4.
TRANSMISSION PUSHBUTTON SHIFT SELECTOR DOES NOT OPERATE).
(b)
If WTEC II TEPSS or WTEC III TPSS displays any other setting than neutral (N), press N or
WTEC II TEPSS or WTEC III TPSS.
If WTEC II TEPSS or WTEC III TPSS is in neutral (N), perform step 4 of this fault.
If WTEC II TEPSS or WTEC III TPSS will not go in to neutral (N), beeps or displays "--" perform
Transmission System.
(c)
Position master power switch to off (para 2-27f).
