PROCEDURE
(a) Measure the auxiliary battery voltage with the power switch off. Standard Voltage: 11 to 14 V If the voltage is below 11 V, replace or recharge the auxiliary battery before proceeding to the next step.
(a) Adjust the reflector height. Click here
(b) Place the reflector. Click here
(c) Connect the Techstream to the DLC3. (d) Turn the power switch on (IG). (e) Turn the Techstream on. (f) Turn the cruise control main switch on. (g) Enter the following menus: Body Electrical / Pre-Collision 2 / Utility / Front Beam Axis Misalignment Reading. (h) Check the amount of misalignment and make a note. Body Electrical > Pre-Collision 2 > Utility
(i) Enter the following menus: Body Electrical / Pre-Collision 2 / Utility / Front Beam Axis Offset Reading. (j) Check the amount of misalignment and make a note. Body Electrical > Pre-Collision 2 > Utility
(k) Calculate the "Dealership Axis Offset Angle (with On-line Calibration Angle)" using the values "Front Beam Axis Misalignment Reading" and "Front Beam Axis Offset Reading". (1) "Dealership Axis Offset Angle (with On-line Calibration Angle)" = "Front Beam Axis Misalignment Reading" - "Front Beam Axis Offset Reading" Standard: Dealership Axis Offset Angle (with On-line Calibration Angle)
(a) Using the Techstream, check that the CAN communication system is functioning normally. Click here OK: CAN communication system is functioning normally.
(a) Check for DTCs. Body Electrical > Combination Meter > Trouble Codes
(a) Use the Techstream to check if the electronically controlled brake system is functioning normally. Chassis > ABS/VSC/TRAC > Trouble Codes
(a) Use the Techstream to check if the electric parking brake system is functioning normally. Chassis > Electric Parking Brake > Trouble Codes
(a) Check for DTCs and note any codes that are output. Powertrain > Radar Cruise1 > Trouble Codes Powertrain > Radar Cruise2 > Trouble Codes(b) Clear the DTCs. Powertrain > Radar Cruise1 > Clear DTCs Powertrain > Radar Cruise2 > Clear DTCs(c) Recheck for DTCs. Try to reproduce the DTCs by duplicating the conditions indicated by the DTCs. Powertrain > Radar Cruise1 > Trouble Codes Powertrain > Radar Cruise2 > Trouble Codes
