(EL-241)Engine trouble data and
NATS trouble data have
been detected in ECMÐ
*: When NATS detects trouble, the security indicator lights up while ignition key is in the ªONº position.
*: When the vehicle is equipped with a dongle unit (RHD models for Europe), the security indicator blinks 6 times just after the ignition
switch is turned to ON. Then the security indicator lights up while the ignition key is in the ªONº position.

whether the NAVI control unit is mal-
functioning or not. If no failure is

tion
GPS input line connection error
GPS TCXO overThe transmission circuit of the GPS
board frequency synchronization oscilla-
tor (inside the NAVI control unit) is send-
ing an oscillation frequency that is
greater or less than the set value.A location error occurs. Strong electro-
magnetic wave interference may have
occurred. The GPS antenna may be in a
very hot or very cold environment. This
is usually a temporary malfunction.Ð
GPS TCXO under
GPS ROM malfunction
Internal malfunction of GPS board RAM
or ROM inside the NAVI control unit.Perform self-diagnosis to confirm
whether the NAVI control unit is mal-
functioning or not. If no failure is
detected, a momentary and/or tempo-
rary malfunction may have been caused
by strong electromagnetic wave interfer-
ence.EL-278 GPS RAM malfunction
GPS RTC malfunctionMalfunction of GPS board clock IC
inside the NAVI control unit.
GPS antenna disconnected ÐPerform self-diagnosis to confirm GPS
antenna connection. If no failure is
detected, a momentary and/or tempo-
rary malfunction may have been caused
by a strong impact.EL-278
Low voltage of GPSPower supply voltage for GPS board
inside the NAVI control unit is low.1. Check power supply circuits for NAVI
control unit.EL-306
2. Perform self-diagnosis to confirm
GPS antenna connection.EL-278
3. If above diagnosis results are OK, a
momentary and/or temporary malfunc-
tion may have been caused by a strong
