DIAGNOSIS SYSTEM
1. DESCRIPTION
(a) When troubleshooting OBD II (On-Board Diagnostics) vehicles, an OBD II scan
tool (complying with SAE J1978) must be connected to the DLC3 (Data Link Connector
3) of the vehicle. Various data in the vehicle ECM (Engine Control Module) can be
then read.
(b) ...
Freeze Frame Data
FREEZE FRAME DATA
DESCRIPTION
(a) Whenever a lane departure alert system is stored, the forward recognition
camera stores the current vehicle state (ECU and sensor information) as Freeze Frame
Data.
CHECK FREEZE FRAME DATA
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch ...
Front Camera Module Circuit (C1AA0)
DESCRIPTION
The millimeter wave radar sensor assembly receives information about the area
in front of the vehicle from the forward recognition camera.
If the millimeter wave radar sensor assembly detects a malfunction in the forward
recognition camera, it will store DTC C1AA0.
