ET042
(CONTINUED 1)
INACTIVEWhen the main switch is in the rest (or neutral) position, status ET042 is INACTIVE.
If "CRUISE CONTROL" or "SPEED LIMITER" appears despite the main button being in
the rest position (or neutral), carry out the following operations:
Check the connections of the cruise control/speed limiter main switch.
Check for + 12 V APC on the main switch connector.
Disconnect the main switch and with it in the rest position, check the insulation
between:
Injection computer A black,
●32-track track A2 Cruise control On/Off button, 6-track
connector track A3
●32-track track C3 Speed limiter On/Off button, 6-track
connector track B1
– Check the continuity between track C3 (injection computer, connector A, black) and
the speed limiter On/Off button 6-track connector track B1 in the speed limiter
position.
– Check the continuity between track A2 (injection computer, connector A, black) and
the cruise control On/Off button 6-track connector track A3 in the cruise control
position.
If these checks are not in order, replace the switch.
Check the continuity, insulation and the absence of interference resistance on the
following connections: Injection computer connector A, black,
●32-track track A2 Cruise control On/Off button, 6-track
connector track A3
●32-track track C3 Speed limiter On/Off button, 6-track
connector track B1
Repair if necessary.
Check the engine management computer connections.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
tool.
