THE FAULT HAS BEEN RECORDED IN CUR-
RENT STATUS:
The control circuit gave a negative result when
switching to "ON".
AHEAD go to 8
3 Select the "PARAMETERS" function on the
menu.
Check the number of «lost synchronisations»:
1 TOOTH and > 1 TOOTH
YES go to 4 NO go to 5
4 THE INDICATION INCREASES PROGRES-
SIVELY OVER TIME WITH THE ROTATION OF
THE ENGINE.
AHEAD go to 8
5 INDICATION = 1-3
THE RPM-TIMING CIRCUIT IS IN COMPLI-
ANCE.
Make an attempt to start and use the parameters
function to check for the «engine revs» indication.
YES go to 6 NO go to 7
6 The signal panel is in conformance.
7 CHECK THE AIR GAP AND MAGNETIC AC-
TIVITY OF THE SENSOR.
See engine mechanics.
8 Check the sensor and related connection circuit
with the control unit.
AHEAD go to 9
9 Install the connection wiring between the control
unit and injection system. Do not make the con-
nection with the control unit.

10 Install the connection connector between the rpm timing sensor and injection system.
Measure the sensor resistance by connecting a multimeter between the terminals marked + and - (see
the "Electrical system" chapter).
