INITIALIZATION RESET TRANSAXLE COMPENSATION CODE NOTICE:
HINT: The ECM (ECT) memorizes the vehicle conditions when controlling the automatic transaxle assembly and engine assembly. Therefore, if the automatic transaxle assembly or ECM has been replaced, it is necessary to reset the memory so that the ECM can memorize the new information. The reset procedure is as follows: (a) Make sure the shift lever is in P or N. (b) Connect the Techstream to the DLC3. (c) Turn the engine switch on (IG). (d) Turn the Techstream on. (e) Enter the following menus: Powertrain / Transmission / Utility / A/T Code Reset. Powertrain > Transmission > Utility
(f) Press "Next" again to proceed. NOTICE: After the transaxle compensation code is initialized, perform Reset Memory and Perform Road Test to Allow ECM to Learn. (g) Press "Exit". RESET MEMORY NOTICE:
HINT: The ECM (ECT) memorizes the vehicle conditions when controlling the automatic transaxle assembly and engine assembly. (a) Connect the Techstream to the DLC3. (b) Turn the engine switch on (IG). (c) Turn the Techstream on. (d) Enter the following menus: Powertrain / Transmission / Utility / Reset Memory. Powertrain > Transmission > Utility
(e) Press "Next". NOTICE: After performing Reset Memory, be sure to perform Perform Road Test to Allow ECM to Learn. PERFORM ROAD TEST TO ALLOW ECM TO LEARN CAUTION:
(a) The "road test" procedure is as follows: (1) Warm up the engine. (2) According to the replaced parts, perform the appropriate road test shown below.
HINT:
NOTICE:
(3) Repeat the road test until the shift shock and engine speed overrun (engine speed flare when shifting) reach an acceptable level. NOTICE: When repeating the acceleration/deceleration cycle of a road test pattern, bring the vehicle to a complete stop before accelerating again. PERFORM ATF THERMAL DEGRADATION ESTIMATE RESET NOTICE: If either of the following conditions is met, perform ATF Thermal Degradation Estimate Reset:
(a) Turn the engine switch off. (b) Connect the Techstream to the DLC3. (c) With the shift lever in P, turn the engine switch on (IG). NOTICE: Do not start the engine. (d) Turn the Techstream on. (e) Enter the following menu: Powertrain / Transmission / Utility / ATF Thermal Degradation Estimate Reset. Powertrain > Transmission > Utility
(f) According to the display on the Techstream, initialize the estimated thermal degradation value. |
Toyota Avalon (XX50) 2019-2022 Service & Repair Manual > Lane Departure Alert System (w/ Steering Control)(for Gasoline Model): Yaw Rate Sensor Circuit (C1AA4,C1AA5)
DESCRIPTION The forward recognition camera receives vehicle stability signals from the yaw rate sensor (airbag ECU assembly). If the yaw rate sensor (airbag ECU assembly) detects an abnormal yaw rate sensor signal or yaw rate sensor power supply voltage, it informs the forward recognition camera via ...
