Automatic Transmission Calibration
- Calibration must be performed at 5000 mile service, after replacement of any major system components, or after any major engine or transmission work. This is because adaptive values created by system before major repairs may no longer be valid.
- Before calibration, adjust kickdown cable by loosening clamp on cable sheath. Leave kickdown cable attached to lever. Move lever to fully extended position (right side of vehicle), against mechanical stop. Hold lever in this position until completed with step 3).
- Pull kickdown cable sheath past kickdown position to full throttle mechanical stop in transmission. Tighten kickdown cable sheath clamp while holding full throttle position.
- Start engine and bring it to normal operating temperature. Turn engine off. Connect ISAT and Capacitor Lead (86 11 048) to Black diagnostic connector. Turn ignition on. Select DIAG, ONE system from ISAT menu, and enter system No. 3. Check if any fault codes are stored in memory. If fault codes are present, perform whatever diagnosis is necessary. See ETS SYSTEM FAULT CODES table. Erase fault codes before proceeding.
- Ensure ignition is on, but engine not running. Enter command Code No. 971. Several seconds after entering command code No. 971, ISAT will terminate communications. Wait 30 seconds while ASR and ETS store baseline settings.
- Reestablish communication with ISAT. With ignition on, engine off, enter command Code No. 973. After TCS CTRL light goes on, start engine but do not touch pedals. Wait for idle to stabilize at around 850 RPM. When TCS CTRL light starts to flash, press and hold cruise control SET SPEED button within 10 seconds, and keep SET SPEED button depressed until calibration process is complete (TCS CTRL light will shut off). ETS ECU will pull KDW to its maximum position and idle position, and will also increase engine speed to about 3000 RPM.NOTE: Calibration procedure will be discontinued if SET button is not depressed within 10 seconds of TCS CTRL light beginning to flash, SET button is depressed before TCS CTRL light starts to flash, SET button is released before calibration process is completed, SET button is inoperative, pedal is depressed, vehicle starts to roll, or gear selector position is changed.
- When calibration is complete, TCS CTRL light will shut off. Stop ISAT communications, turn off engine, and recheck to see if any fault codes were stored during calibration procedure.
- If a new ETS ECU is installed, coding for engine variant must be entered by ISAT. For automatic transmission equipped vehicles, enter ISAT command Code 97A. ISAT should now display 802.3TA.
