INSPECT BATTERY VOLTAGE |
(a) Measure the battery voltage with the ignition switch off.
Standard Voltage:
11 to 14 V
If the voltage is below 11 V, replace or recharge the battery before proceeding to the next step.

(c) Connect the Techstream to the DLC3.
(d) Turn the ignition switch to ON.
(e) Turn the Techstream on.
(f) Turn the cruise control main switch (ON-OFF) 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.
(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.
(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)
|
Vertical |
-5.2 to 5.2 deg. |
|
Horizontal |
-0.6 to 0.6 deg. |
|
Result |
Proceed to |
|---|---|
|
The dealership axis offset angle (with on-line calibration angle) is within the specified range. |
A |
|
The dealership axis offset angle (with on-line calibration angle) is not within the specified range. |

Wireless Charger Illumination Circuit
DESCRIPTION
When the light control switch is turned to the tail or head position, this circuit
sends an illumination signal to the mobile wireless charger cradle assembly. Based
on this signal, the mobile wireless charger cradle assembly dims the indicator lights
(green and amber).
