C1893; LEFT-HAND REAR HEIGHT SENSOR SIGNAL CIRCUIT FAULT

G256924t62: CHECK THE LEFT-HAND REAR SIGNAL CIRCUIT FOR SHORT TO B+
1. Disconnect the left-hand rear height sensor electrical connector, CV03.
2. Measure the voltage between CV03, pin 04 (BR) and GROUND.
^ Is the voltage greater than 3 volt?
-> Yes
REPAIR the short circuit. CLEAR the DTC. TEST the system for normal operation.
-> No

G256924t63: CHECK THE LEFT-HAND REAR SIGNAL CIRCUIT FOR SHORT TO GROUND
1. Measure the resistance between CV03, pin 04 (BR) and GROUND.
^ Is the resistance less than 10,000 ohms?
-> Yes
REPAIR the short circuit. CLEAR the DTC. TEST the system for normal operation.
-> No

G256924t64: CHECK THE LEFT-HAND REAR SIGNAL CIRCUIT FOR HIGH RESISTANCE
1. Disconnect the battery negative terminal.
2. Disconnect the ASU electrical connector, CR90.
3. Measure the resistance between CR90, pin 08 (BR) and CV03, pin 04 (BR).
^ Is the resistance greater than 5 ohms?
-> Yes
REPAIR the high resistance circuit. CLEAR the DTC. TEST the system for normal operation.
-> No
CHECK for DTCs indicating a sensor fault. Contact dealer technical support for confirmation of possible module failure, and/or raise an EPQR.
