  Q: How to install the Cruise Control Module Assembly and perform the necessary initialization steps on Toyota Avalon?

  A:

  Begin Distance Control ECU Assembly installation by fixing the bolt at 5.0 Nm (51 kgf-cm, 44 in-lbf) torque and then attach the connector. Start by installing the Instrument Panel Air Bag Assembly Lower No. 1 and then connect the cable to the negative battery terminal before a system initialization if needed since disconnecting the cable can require it. Users must inspect the SRS warning light while initializing the Distance Control ECU Assembly through this procedure: Turn on the Ignition Switch (IG) then activate the cruise main switch while keeping the brake pedal depressed and pressing the cruise control main switch to RES/ACC three times within three seconds followed by verifying a buzzer sound. The optical axis should not be adjusted by operating the headlight Dimmer Switch while performing this process. In case a mistake with the switch occurs, reset the optical axis.

  Q: How to service and repair the Cruise Control Module on Toyota Avalon?

  A:

  The first step when servicing or repairing the Distance Control ECU requires disconnecting the battery cable from the negative terminal before waiting 90 seconds to avoid Air Bag deployment. The first step of servicing the Distance Control ECU involves removal of the instrument cluster finish panel garnish No.1 followed by the instrument panel finish plate then the instrument panel sub-assembly along with the instrument panel finish lower panel LH and instrument panel Air Bag assembly lower No.1. The Distance Control ECU assembly needs to be removed once the bolt is unscrewed and the connector is detached. Installation starts with placing the Distance Control ECU assembly and tightening its bolt to 5.0 N.m (51 kgf.cm, 44 in.lbf) before reattaching the connector. Reinstall the instrument panel Air Bag assembly lower No.1 but keep the cable connected to the negative battery terminal before doing system initialization that becomes necessary upon battery disconnection. During SRS warning light inspection turn on the Ignition Switch (IG) then activate the cruise main switch followed by pressing the cruise control main switch to RES/ACC three times within three seconds while depressing the brake pedal to produce buzzer sounds. Turning on the headlight Dimmer Switch must be avoided because it leads to wrong optical axis adjustments but optical axis adjustment is needed if the switch turns on by mistake.
