REV COUNTER INSTRUMENT
Fault finding - Function
System outline
The system is composed solely of an offset rev counter on the instrument panel facing the driver, which incorporates
its own computer.
The function of the “rev counter” system' is:
●To display the "engine speed" signal image in rpm sent by the injection computer on the multiplex
network.
●To identify the traction control system warnings on equipped vehicles.
Depending on the configuration, when the lights are switched on, the rev counter backlighting may vary depending
on the instrument panel backlighting dimmer request, the light signal is sent on the multiplex network by the
instrument panel.

CONFIGURATION CHECK
ESP configuration check depending on equipment:
Check if the vehicle is fitted with the ESP system (ESP button on the console).
If the vehicle is fitted with the ESP system, when the + after ignition feed is switched on, the indicator light should
come on for 3 seconds. In the event of a fault, configure the rev counter using the command CF002 ELECTRONIC
STABILITY (ESP) CONTROL (see Configuration).
Dimmer lighting function check:
With the side lights on, activate the rev counter variation control, the rev counter lighting varies at the same time.
If the rev counter lighting does not change, check the configuration of the rev counter using configuration reading
LC003 DIMMER LIGHTING (see Configuration) and configure the rev counter in accordance with the requirements
using command CF003 DIMMER LIGHTING (see Configuration).

Fault finding - Interpretation of statuses
ET002
SIDE LIGHTS SWITCH
STATUS
DEFINITION–ACTIVE: This status indicates that the side light control is active.
–INACTIVE: This status indicates that the side light control is inactive.
NOTES–Ignition on.
–Side lights on.
If the status of the side light control remains at status INACTIVE, apply the following fault finding procedure.
Check fuse F43 (10A) of the passenger compartment fuse box, component code 1016.
Check that the connection and condition of the rev counter connector are correct (see Wiring Diagram Technical
Note, Twingo II, Component code 995).
If there is a repair method (see Technical Note 6015A, Electrical wiring repair, Wiring: Precautions for repair)
repair the connector, otherwise replace the wiring.
Check the + 12 V feed on connection LPG of component 995.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair) repair the wiring, otherwise replace it.
Check the continuity and insulation of:
Connection LPG between the passenger compartment fuse box, component code 1016 and the rev
counter, component code 995.
Connection MAM of the rev counter, component code 995.
Connection MAN of the rev counter, component code 995.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair) repair the wiring, otherwise replace it.
If the fault is still present, contact the techline.
