STOREDABS MULTIPLEX SIGNAL
1.DEF: No multiplex frameworks or invalid values (signal producing computer
problem or multiplex line connection fault).
NOTESSystem effects:
The lock-up is inhibited (still open).
Customer complaint:
If the lever is in position "P", the "Apply brake" icon is not displayed on the instrument
panel.
The function reducing drag when stationary is no longer operational.
Use the Wiring Diagrams Technical Note, SCENIC II ph2.
Run a multiplex network test (see 88B, Multiplex).
Run a check on the ABS anti-lock braking system (see 38C, ABS Bosch 8.0).
Check the continuity and insulation against earth of the following connections:
●Connection code 3MS,
●Connection code 3MT,
between components 119 and 120.
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 the fault is still present, contact the Techline.
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.

ENGINE BRAKE
1.DEF: Hydraulic, mechanical or electrical fault on solenoid valves, deal with the
other faults first
NOTESOrder of priority in the event of more than one fault:
If there is a combination of the following faults:
–DF300 "Brake 2 solenoid valve circuit"
–DF306 "Lock-up/brake 1 solenoid valve circuit",
–DF307 "Engine brake",
deal first with faults DF300 "Brake 2 solenoid valve circuit" and DF306 "Lock-up/
brake 1 solenoid valve circuit".
Conditions for applying fault finding procedures to stored faults:
The fault appears after:
Lever in "Drive" position.
The solenoid valve control status corresponds to a fault
OR the pressure switch status corresponds to a fault.
System effects:
Significant engine braking.
lock-up inhibited (i.e. open) to avoid stalling.
Customer complaint:
Major engine braking when the fault appears, then a complete absence of engine
braking.
Fault warning light comes on.
Look for any damage to the wiring harness, and check the condition and connection of the automatic
transmission computer and the hydraulic distributor.
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.
Is the + after ignition feed still present?
If YES, move on to step 1.
If NO, 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.

ET018
BRAKE PEDAL
Note:
Status ET018 "Gear engaged" is applicable to the following sub-functions:
–"Driver parameters".
STATUS
DEFINITIONDEPRESSED: shows that the brake pedal is depressed.
RELEASED: shows that the brake pedal is released.
STATUS1: shows that the brake switch signal is invalid.
NOTESSpecial notes:
Apply the conformity check to see if the statuses are consistent with the operating
programs of the system.
Conformity check with engine stopped, ignition on or engine running.
"DEPRESSED"
(Brake pedal
depressed)
When the driver depresses the brake pedal status ET018 Brake pedal becomes
DEPRESSED.
If the driver depresses the brake pedal hard and status ET018 Brake pedal remains
RELEASED with the lights operating:
Check the insulation, continuity and the absence of interference resistance on the
following connection:
–Connection code 5A
between the brake light switch connector, component code 160 and the transmission
computer, component code 119.
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.
–Remove the brake light switch and carry out the following checks:
Continuity between
connectionsInsulation between
connections
Brake pedal depressed65A and SP17 5A and BPT
Brake pedal released5A and BPT 65A and SP17
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.
