No Power Supply. Intermittent Fault

No power supply. Intermittent fault

Checking cables

Note! This diagnostic trouble code (DTC) may have been stored during transportation between the factory and dealership. Check that the transit safety catch in the integrated relay/fusebox in the engine compartment is correctly connected.

Check that battery voltage is normal and that the charging system functions. When the generator (GEN) is charging the voltage should be 12-15V.
Check the climate control module connector A (30-pin) and the integrated relay/fusebox in the engine compartment. Check for contact resistance and oxidation.
Check fuse 8 (10 A) in the engine compartment integrated relay / fusebox.
Check the cable between climate control module terminal #A1 and fuse 8 (10 A) in the integrated relay/fusebox in the engine compartment. Check for a short-circuit to ground. Check for an open-circuit.

Hint: For further information about the circuit after the fuse, see the Wiring Diagram Service Manual.

Remedy as necessary

- To connect the breakout box, see Connecting the breakout box, climate control module Connecting The Breakout Box
- The cable should have battery voltage regardless of the position of the ignition switch. For other values, see Climate control signal specifications Signal Specification

Fault-tracing information
If the fault is intermittent, do not verify fault-tracing if the fault does not recur.
It is possible to view the information again, or leave fault-tracing for this diagnostic trouble code (DTC).
