ET047 Inconsistency without depressing the pedal.
Check the condition and connection of the brake pedal switch connector.
If the connector is faulty and if there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the connector; otherwise, replace the wiring.
With the brake pedal switch disconnected:
Check the insulation between connections 65A and SP17 of component 160 (brake light switch piston pressed).
Only replace the brake pedal switch if it is not correct.
Check the condition and connection of the UCH connector PE2.
If the connector is faulty and if there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the connector; otherwise, replace the wiring.
With the UCH and brake pedal switch disconnected:
Check the insulation in relation to + 12 V of connection 5A between components 645 and 160.
The line is shared with the ABS computer or the electronic stability program (ESP) relay (depending on equipment)
and the brake lights.
In the event of faulty insulation, use a wiring diagram to check the connections between the brake pedal switch
connector and these components.
If the fault is still present, contact the Techline.
AFTER REPAIRCarry out another fault finding check on the system.
Clear the stored faults.
Deal with any other faults.

ET047 Undetermined with the pedal depressed.
Check the condition and connection of the brake pedal switch connector.
If the connector is faulty and if there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the connector; otherwise, replace the wiring.
With the brake pedal switch disconnected:
Check for + 12 V on component 160 on connection SP17.
If not correct:
–Check the condition and connection of fuse 1H in the passenger compartment relay and fuse box.
–Check the condition and the connection of the passenger compartment fuse and relay box connector. If the
connector is faulty and if there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the connector; otherwise, replace the wiring.
–Check the insulation and continuity of connection SP17 between components 160 and 260. If the connection
is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair, Wiring:
Precautions for repair), repair the wiring, otherwise replace it.
If it is still faulty, contact Techline.
With the brake pedal switch disconnected:
Check the continuity of the following connections:
●Connection code 65A,
●Connection code SP17 of component 160 (brake pedal switch piston free).
Only replace the brake pedal switch if it is not correct.
Check the condition and connection of the UCH connector PE2.
If the connector is faulty and if there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the connector; otherwise, replace the wiring.
With the UCH and brake pedal switch disconnected:
Check the insulation and continuity of the following connection:
●Connection code 65A between components 645 and 160.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
The line is shared with the ABS computer or the ESP relay (depending on equipment) and the brake lights. In the
event of faulty insulation, it is therefore necessary, using a wiring diagram, to check the connections between the
brake pedal switch connector and these components.
AFTER REPAIRCarry out another fault finding check on the system.
Clear the stored faults.
Deal with any other faults.
