C1203 code on 03 sequoia


This communication code (C1203) will be set any time the check engine light comes on. The data link between the two computers becomes interrupted when there is a malfunction in the engine control computer or if the brake warning light is illuminated. The code itself is nothing to be worried about unless it won't clear and this is causing the lights for the VSC system to remain on. If this is the case then there is a problem in the communication line between the VSC computer and the engine control computer. This is extremely unlikely though. Remove the negative battery cable to erase all the memories in the on board systems then see if everything functions normally and this 1203 code disappears

My '93 suzuki sidekick automatic transmission 4 wheel drive after warm up "overdrive off" starts flashing on and off and when on the drivetrain stops working


The O/D light's flashing means there is some kind of transmission trouble.

The codes are..


Trouble Code (1) Probable Cause
12 ............................... System Operation Normal
21 ..................... No. 1 Shift Solenoid Open Circuit
22 .................... No. 1 Shift Solenoid Short Circuit
23 ..................... No. 2 Shift Solenoid Open Circuit
24 .................... No. 2 Shift Solenoid Short Circuit
25 ............................. TCC Solenoid Open Circuit
26 ............................ TCC Solenoid Short Circuit
31 ............ Vehicle Speed Sensor Open Or Short Circuit
32 ................ Throttle Position Sensor Short Circuit
33 ................. Throttle Position Sensor Open Circuit
34 ................ Defective Park/Neutral Position Switch
36 .............. (2) No Signal-Both Vehicle Speed Sensors
(1) - Check listed component for probable cause. Also check wiring and connections of specified component.
(2) - No signal from both transmission and speedometer mounted vehicle speed sensors.

If a trouble code is present, OD OFF light will flash a trouble code. The number of flashes will equal first digit of trouble code. After a one second pause, second digit will be displayed. If more than one trouble code is present, next trouble code will be displayed after a 3 second pause. Smallest number trouble code will be displayed first. Trouble codes will be repeated.

Hope this gave you some insight on the issue.

2003 toyota abs light Codes C1203, C1223


C1223 - Left Rear Wheel Speed Sensor Input Signal is 0 C1203 - The procedure for this fault is to check for an open or short in the harness and connector between the Skid control ECU and ECM.If no faults are found with the wiring, then - the MIL stays off when ignition on but engine not running (Requires ECM replacing)
- the MIL comes on when ignition on but engine not running (requires ABS & traction actuator assembly)
These parts wont be cheap so i hope its a wiring fault smile.gif
If you take it to a Toyota dealership they should be able to do this for you pretty easily.

My 2003 Hyundai Santa Fe ABS light is staying on but the ABS is not engaged.


Here are all the possible problems which can turn on your ABS light.

C1101 Battery voltage over volt: 18V or more ○ ○ BR - 69
C1102 Battery voltage low volt: 9.5V or less ○ ○ BR - 69
C1200 FL wheel sensor: open or short to ground ○ ○ BR - 66
C1201 - Range/Performance: speed jump or damaged exciter ○ ○ BR - 67
C1202 - No signal: air-gap error or wrong excite ○ ○ BR - 68
C1203 FR wheel sensor: open or short to ground ○ ○ BR - 66
C1204 - Range/Performance: speed jump or damaged exciter ○ ○ BR - 67
C1205 - No signal excite: air-gap error or wrong excite ○ ○ BR - 68
C1206 RL wheel sensor: open or short to ground ○ ○ BR - 66

C2227 Brake disc overheat δ ○
C1274 G-Sensor signal fail (only 4WD) ○ ○ BR - 72
C1275 G-Sensor open or short to ground (only 4WD) ○ ○ BR - 72
You'll need a scanner which is compatible with Hyundai's ABS system to retrieve any DTC's (Diagnostic Trouble Codes) stored in its computer. Any time the ABS light comes on, there's a DTC stored in its computer - that code will tell you where the problem exists. Then you can go from there.

Air bag sensor keeps flashing


If a concern is detected, the air bag control module will communicate by flashing the warning indicator. A diagnostic trouble code (DTC) is logged by the air bag control module in a nonvolatile memory. For additional information, refer to Diagnosis and Testing in this section.
Lamp Fault Codes (LFC)
Item Part Number Description 1 One flash cycle: Driver air bag trouble code 2 Two flash cycle: Passenger air bag trouble code 3 Three flash cycle: Trouble code common to both driver and passenger air bag circuit 4 Four flash cycle: Safety belt pretensioner trouble code common to both driver and passenger pretensioner circuits 5 Five flash cycle: Driver side air bag trouble code 6 Six flash cycle: Passenger side air bag trouble code 7 Not used 8 Not used

Airbag flashes 10 times misses a flash then repeats


Try clearing the codes & see if it returns. I do not see a code fault 10. Starts at 12.

---------------------------------------------------------------------
Section 01-20B: Restraints, Passive — Supplemental Air Bag System 1995 Town Car, Crown Victoria, Grand Marquis Workshop Manual DIAGNOSIS AND TESTING Diagnostic Trouble Code Clearing Procedure to Clear Diagnostic Trouble Codes from Diagnostic Monitor Non-Volatile Random Access Memory.
Normal Operation
The air bag diagnostic monitor (14B056) continually checks the air bag system for readiness. When a fault condition is detected, the DTC associated with that fault is stored in the air bag diagnostic monitor's Non-Volatile Random Access Memory (NVRAM). After writing the DTC to NVRAM, the air bag diagnostic monitor signals the fault by flashing the appropriate diagnostic trouble code on the air bag indicator. The diagnostic trouble code written to NVRAM is permanently stored in the air bag diagnostic monitor until cleared by the diagnostic trouble code clearing procedure.
  • Upon each cycle of the ignition switch (11572) , the air bag diagnostic monitor checks for diagnostic trouble codes written in NVRAM. If any diagnostic trouble codes exist in NVRAM, the air bag diagnostic monitor will then check to see if these fault conditions are still present.
  • If the conditions of the diagnostic trouble code in NVRAM are still present, then the air bag diagnostic monitor will use the air bag indicator to flash out the diagnostic trouble code number that was written in memory.
  • If the conditions of the diagnostic trouble code are not still present (indicating an intermittent or serviced fault), the air bag diagnostic monitor will use the air bag indicator to flash out a DTC which is the sum of the diagnostic trouble code in NVRAM plus 40.
Example: Due to corrosion, high resistance develops on the driver side air bag circuit. The air bag diagnostic monitor stores a diagnostic trouble code 32 in NVRAM. Upon each cycle of the ignition switch , the air bag diagnostic monitor checks the resistance of the driver air bag circuit.
  • If the resistance is still high, the air bag diagnostic monitor causes the air bag indicator to flash out a DTC 32.
  • If the resistance falls within the normal range due to service or an intermittent condition, the air bag diagnostic monitor causes DTC 72 to be flashed on the air bag indicator.
Once a fault has been serviced, the associated diagnostic trouble code may be cleared from NVRAM. Only diagnostic trouble codes that the air bag diagnostic monitor sees as repaired or intermittent may be cleared (diagnostic trouble codes 52 and above). In no circumstances can hard fault conditions (diagnostic trouble codes 45 and below) be cleared.
  1. Follow the diagnostic procedures as outlined to service the fault condition flashing on the air bag indicator.
  1. Cycle the ignition switch to OFF and then to RUN.
  1. Observe air bag indicator prove-out (six ± two seconds) followed by diagnostic trouble code (52-85) flashing completely one time.
  1. Locate the Diagnostic "Trouble Code Clear" Connector located underneath the glove compartment (06010) containing Circuits 631 (T/R) and 57 (BK).
  1. Use a jumper wire to short Circuit 631 (T/R) to Circuit 57 (BK) or to another good ground. This short must be made after the diagnostic trouble code flashes completely one time, but before the warning light stays on continuously.
  1. Hold short until air bag diagnostic monitor tone sounds (approximately five seconds).
  1. Release short on Circuit 631 (TAN/RED STRIPE) to Circuit 57 (BLACK). This short must be released within 25 seconds after the diagnostic monitor tone sounds. Diagnostic trouble code is now cleared from NVRAM. Next highest priority diagnostic trouble code stored in NVRAM (if one exists) will begin flashing.
