ET001
REVERSE GEAR ENGAGED
NOTESSpecial note:
Only carry out the checks if the YES and NO statuses are not consistent with the
position of the gear lever.
Check that the reversing lights are working properly: they should come on when reverse gear is engaged and go
out when shifting out of reverse
Check for the presence and condition of fuse F6 (15A); replace it if necessary.
Check for the + 12 V supply on connection AP3 between components 155 and 1016.
If the reversing lights fail to function as specified:
With the ignition switched off, disconnect the parking distance control computer connector to check the
insulation (against + 12 V), the continuity and the absence of interference resistance on the following
connection:
Connection code H66P between components 1222 and 172.
Connection code H66P between components 1222 and 173.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check that the reverse gear switch is operating correctly.
If the fault is still present, replace the reverse gear switch.
If the lights come on and the connections are correct, contact the Techline.
If the fault is still present, contact Techline.
AFTER REPAIRRepeat the conformity check from the start.

NOTESOnly investigate this customer complaint after a full check using the diagnostic tool
(there must be no present or stored faults).
Using the diagnostic tool Main Data screen, check
that the parking distance control system is on.
The status ET003 Parking proximity sensor
function must be READY (and the red warning light
on the parking proximity sensor switch must be off).
Is status ET003 Parking proximity sensor
"READY"?
YES
Using the diagnostic tool's Main Data screen,
check that reverse gear is selected.
The ET001 Reverse gear selected status must be
YES.
Also ensure that the reversing lights come on when
reverse gear is selected.
Is status ET001 YES?
