CO.1: Short circuit or open circuit to + 12 V
NOTESConditions for applying fault finding procedures to stored faults:
The fault is declared present after:
–in the event of short circuit+:
Lever in "Drive" position, gear engaged = 2, 3, 4, 5, 6,
and Inconsistency between the solenoid valve control status and the control voltage.
–in the event of open circuit:
Lever in "Drive" position, lock-up closed, gear engaged = 2, 3, 4, 5, 6,
and Inconsistency between the solenoid valve control status and the control voltage.
–in the event of short circuit-:
Lever in "Drive" position, lock-up open, gear engaged = 1, 2, 3, 4, 5, 6,
OR Gear 1 with engine braking,
and Inconsistency between the solenoid valve control status and the control voltage.
OR
Running command AC002 "Shift solenoid 2".
Effect on system:
–in the event of short circuit+:
If the fault appears with the lock-up closed, gear engaged in "Drive" position = 2, 3, 4,
5, 6, automatic transmission is locked.
–in the event of open circuit:
No effect.
–in the event of short circuit-:
Risk of stalling in 1st with engine braking.
Customer complaint:
If the fault occurs while driving, the transmission engages fixed 5th gear.
Restarting is in 3rd gear.
Fault warning light comes on.
Use the Wiring Diagrams Technical Note, SCENIC II ph2.
Look for any damage to the harness and check the condition and connection of the automatic transmission
computer and automatic transmission connectors.
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.
Check for + after ignition feed on connection 5LW of component 754.
If + after ignition feed is present, move on to step 1.
If + after ignition feed is not present, move on to step 8.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition, wait 1 minute and carry out a road test followed by another
check with the diagnostic tool.
