Codes erreurs

[bano]

Tout d'abord merci à Ferdinotch pour son conseil xp + rs232 car c'est parfait pour lire les codes et effacer le voyant service. avec mon elm 327 USB çà ne fonctionnait pas.

Suite à çà j'ai deux erreurs:

IMM-221/234 No Response from Key Transponder
CI-113 Fuel Level Sensor Signal too high

Pour le premier je pense que c'est parce que je laisse la commande d'ouverture à distance de la voiture à la maison car j'ai eu des problèmes d'alarme.

Pour le deuxième j'ai pu lire sur le net ceci

DTC CI-113
Fuel Level Sensor Signal Interrupted
1) This DTC will set if resistance in fuel level sensor
exceeds 335 ohms for more than 10 seconds. The fuel gauge may read
permanently empty or too low.
2) To correct this problem, check for a break in fuel level
sensor, broken fuel level sensor ground lead, signal leads shorted to
voltage, broken fuel level sensor signal lead, faulty fuel level
sensor (resistance too high), high contact resistance, or poor
contact.

FUEL GAUGE TEST
Fuel Gauge Does Not Operate
1) Turn ignition on. Activate diagnostic test mode No. 3. See
On-BOARD DIAGNOSTICS (1995 MODELS) under SYSTEM TESTING. If fuel gauge
indicates 1/2 full, go to next step. If fuel gauge does not indicate
1/2 full, replace instrument cluster.
2) Turn ignition off. Remove right side panel in trunk.
Disconnect Black 2-pin electrical connector. See Fig. 5. Connect an
ohmmeter between sensor connections. Depending on amount of fuel in
tank, if ohmmeter indicates 7.5-12.5 to 322.5-327.5 ohms, go to next
step and check sensor ground connection. If ohmmeter does not indicate
7.5-12.5 to 322.5-327.5 ohms, replace fuel level sensor.
3) Ensure ignition is off. Connect an ohmmeter between
harness connector terminal No. 2 (Yellow/Red wire) and ground. If
about zero ohms is present, go to next step and check sensor signal
circuit. If about zero ohms is not present, check for an open circuit
in wiring between connector terminal No. 2 (Yellow/Red wire) and 30-
pin connector on instrument cluster.
4) Connect voltmeter between harness connector terminal No. 2
(Yellow/Gray wire) and ground. Turn ignition on. If about 7 volts is
present, replace instrument cluster. If zero volts is present, check
for a short to ground or an open circuit. If battery voltage is
present, check wiring for a short to voltage.

Fuel Gauge Reading Incorrect
1) Turn ignition on. Activate diagnostic test mode No. 3. SeeON-BOARD DIAGNOSTICS (1995 MODELS) under SYSTEM TESTING. If fuel gauge
indicates significantly more or less than 1/2 full, replace instrument
cluster. If fuel gauge indicates 1/2 full, go to next step and check
fuel level sensor ground.
2) Turn ignition off. Remove right side panel in trunk.
Disconnect Black 2-pin fuel level sensor connector. See Fig. 5.
Connect an ohmmeter between connector terminal No. 2 (Yellow/Red wire)
and ground. If zero ohms is present, go to next step and check fuel
level sensor. If zero ohms is not present, check Yellow/Red wire
between connector in trunk and 30-pin instrument cluster connector.
3) Turn ignition off. Locate fuel level sensor Black 2-pin
connector behind right side panel in trunk. Connect ohmmeter between
connector terminals on fuel level sensor side of harness.
4) Depending on amount of fuel in tank, if ohmmeter indicates
7.5-12.5 to 322.5-327.5 ohms, replace instrument cluster. If ohmmeter
does not indicate 7.5-12.5 to 322.5-327.5 ohms, replace fuel level
sensor. If amount of fuel in tank is unknown, remove fuel level sensor
from tank and turn it upside down.
5) Connect an ohmmeter between fuel level sensor connector
terminals. Turn sensor slowly to same position that it had when in
tank. Resistance should rise from about 10 ohms (full tank) to about
325 ohms (empty tank). If resistances are incorrect, replace sensor.
If resistances are correct, replace instrument cluster.
FUEL GAUGE SENDING UNIT TEST
NOTE: On 850, fuel gauge sending unit should not be tested
independently of rest of circuit. For fuel gauge sending
unit testing, see FUEL GAUGE TEST.

Je précise que ma jauge de carburant fonctionne normalement et çà s'allume bien en réserve lorsque c'est le moment.
Ah oui en les effaçant ils ne semblent pas revenir.
Par contre impossible d'effacer le voyant lambda.

D'avance merci pour votre aide
