Intermittent Fault

Internal fault. Intermittent fault

Checking supply
Check passenger compartment fuse 4 (11C/4:2)
Check the cable between the power seat module (PSM) terminal #A1 and passenger compartment fuse 4 (11C/4:2). Check for contact resistance and oxidation. See Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.
If the fuse has blown fault-trace for an intermittent short-circuit to ground. See Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults
Check the connector
Check passenger compartment fuse 24 (11C/24:2)
Check the cable between power seat supply relay (2/29) #3 and passenger compartment fuse 24 (11C/24:2). Check for an intermittent short-circuit to ground. See Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults. Check for contact resistance and oxidation. See Checking wiring and terminals.

Check that the relay is not is defective.
Check the cable between the power seat module (PSM) #B1 and power seat supply relay (2/29) #1. Check for an intermittent short-circuit to ground. See Checking wiring and terminals.

Was a fault detected?

Yes - Fault-tracing information

No - Replacing the component

-------------------------------------------------

Replacing the component
An internal relay in the power seat module (PSM) has stuck in active position.
Try to activate the motor.
Check the supply to the control modules.
If no faults were found, try a new power seat module (PSM).

Fault-tracing information




Information

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).

Do you want to view the information again?

Yes - Attempt New Test

No - Fault Found
