Signal Faulty. Intermittent Fault

Signal faulty. Intermittent fault

Checking the components and wires
The engine control module has detected a fault in the communication between the immobilizer and the engine control module on an earlier occasion.
Visually check the immobilizer connections and connector as described in Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults
Check the signal wire between engine control module B22 ( B32) and immobilizer B5 ( A35) for an intermittent open circuit as described in Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults , for an intermittent short circuit to ground as described in Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults , and for an intermittent short circuit to voltage supply as described in Checking wiring and terminals.

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).
