13
Alignment monitoring failed in azimuth
- Radar sensor is looking too low.
This code may indicate the radar
installation was damaged by impact
(frame cross-member, bumper, radar
bracket, etc.).
This code may also indicate a Radar
Service Alignment was not completed
following axle alignment.
앫
Check for damage to radar sensor, bracket and fascia.
앫
Perform Service Alignment.

4
Electrical supply voltage too low
앫
Verify that the voltage at the radar sensor connector is greater than
6 VDC with a 1 amp load (e.g. tail light or marker light bulb).
앫
Inspect the radar connector for corrosion.
앫
Inspect each of the power connections between the ignition switch
and the radar to determine where loss of power may be occurring.

3
Electrical supply voltage too high
앫
Monitor the battery voltage to determine if the battery is providing
voltage between 10 and 16 VDC.
앫
If the voltage is too high, troubleshoot the voltage regulator and
alternator system.
앫
Determine if a jump start or battery charging has occurred that
could cause a vehicle overvoltage condition.

12
Shutdown by OSEK
앫
Cycle ignition power off for 2 to 3 minutes.
앫
Verify fault does not return.

7
Motor azimuth: Blockage detected
앫
Verify no visible/physical damage to radar.
앫
Check power ground and load test at the radar harness connector.
앫
If fault persists after completing previous checks and repairs, this
may indicate the radar has failed.
