HIGH SPEED FAN RELAY CONTROL CIRCUIT
CC.1 : Short circuit to +12 V
NOTESSpecial notes:
The function is inhibited when the fault is present.
Reactivating the function via a new ignition request.
Measure the resistance between tracks 1 and 2.
If the resistance is not 65 ΩΩ Ω Ω
± 10 ΩΩ Ω Ω
, replace the relay.
Take the relay out and make sure that it is insulated from the +12 V for the connection:
UPC connector PPM2 track 2 Track 2 of the fan relay connector
Repair if necessary.
If the fault is still present, check for the absence of +12 V on track 2 of the UPC connector PPM2.
If +12 V is present, contact the Techline.
AFTER REPAIRClear the computer memory.
Turn the ignition off and then on again, then run a new check using the fault finding tool

+ APC CIRCUIT
DEF : Consistency
NOTESNone.
Check the voltage of the battery.
Check that ET026 + ignition status is consistent
Check the condition of the fuses on the battery positive terminal.
Repair if necessary.
Check the status and the connection of the + battery on the UPC mounting and on the P2 connector.
Repair if necessary.
With the ignition turned off, check that there is no +12 V supply on track 6 of UPC connector PPM2
If the +12 V feed is present, disconnect the following fuses one by one in order to isolate the faulty track:
–fuse 5C (track 6 connector PPM2),
–fuse 5D (track 1 connector PEH),
–fuse 5E (track 10 connector PPH2),
–fuse 5F (track 11 connector PPH2),
–fuse 5G (track 7 connector PPM2),
–fuse 5H (track 10 connector PPM2).
Using an electrical diagram, check the insulation against +12 V, of the connection between the track which
the UPC detected as faulty and the computers or consumers linked to this track.
With the ignition on, check for the presence of +12 V on one of the following UPC tracks:
–track 1 of connector PEH
–tracks 6, 7 and 10 of connector PPM2
–tracks 10 and 11 of connector PPH2
If the fault is still present, contact the Techline.
AFTER REPAIRClear the computer memory.
Turn the ignition off and then on again, then run a new check using the fault finding tool.
