INSPECTION CHART FOR TROUBLE SYMPTOMS
warningWhen touching the throttle valve, surely shut off the driving circuits of the throttle valve. In the event that the throttle valve is operated, a finger might be injured as the result of being caught by the throttle valve.
cautionDuring troubleshooting if the ignition switch is turned to ON with the connectors, etc. disconnected, some diagnosis code may be saved in other system. After the troubleshooting is completed, always make sure the diagnosis codes of the entire systems. If it is found that some diagnosis codes have been set, erase them.
noteWhen the racing (2,000 to 5,000 r/min or more) continues on the vehicle stopped with no load during the specified time or more, the increase in the engine speed might be limited. This comes from the engine protection and control functions and is not a malfunction.
ItemTrouble SymptomInspection Procedure No.Reference Page
Engine warning lampThe engine warning lamp does not illuminate right after the ignition switch is turned to the ON position.1
The engine warning lamp remains illuminating and never goes out.2
StartingStarting impossible
(starter operative but no initial combustion)
The starter is operative and cranks the engine, but no initial combustion occurs in the cylinders to start the engine.3
Starting impossible (initial combustion but no complete combustion)Initial combustion occurs, but the engine stalls soon due to the incomplete combustion.4
Improper starting (long time to start)The engine starts, but it takes too long for cranking.
Improper idlingUnstable idling
(rough idling, hunting)
The engine speed is not constant and fluctuates during the idling. Usually, this malfunction can be judged from the shaking tachometer pointer or vibrations transmitted to the steering wheel, shift lever, vehicle body and so on.5
Improper idling speed (too high or too low)The idling speed is not within the normal range.
Engine stalls during idling
(die out)
The engine stalls during the idling in no relation to the vehicle movement.
Engine stallsThe engine stalls when starting the car (pass out)The engine stalls when the accelerator pedal is depressed in the idling speed, or during the operation.6
The engine stalls when deceleratingThe engine stalls at the deceleration.
DrivingEngine does not revolve upThe engine speed does not increase even when the accelerator pedal is depressed.7
Hesitation, sagThe response of vehicle speed (engine speed) is delayed when the accelerator pedal is depressed to accelerate vehicle speed, or the vehicle speed (engine speed) is temporarily dropped during the acceleration.
This phenomenon is called "hesitation" and a serious hesitation is called "sag".
8
Poor accelerationThe engine operates smoothly at a constant-speed run, but the vehicle does not accelerate properly as the throttle valve opening changes. In addition, vehicle will not run in the specified maximum speed.
StumbleThe engine speed increase is delayed when the accelerator pedal is initially depressed at the starting.
SurgeAt a constant-speed or acceleration the vehicle is subject to repeated jerking (in terms of the drive speed) in the driving direction.
The feeling of impact or vibration when acceleratingThe driver feels a sudden impact when the vehicle is accelerated.9
The feeling of impact or vibration when deceleratingThe driver feels a sudden impact when the vehicle is decelerated.10
KnockingSharp sound like a hammer striking on the cylinder walls during the driving can be heard and wrongly affects the driving.11
Ignition timing deviationThe basic ignition timing is deviated from the datum value.12
Exhaust gasOdour, white smoke, black smoke and high-concentration of CO/HC during idlingThe exhaust has an abnormal odour. Either white or black exhaust gas comes out. The concentration of CO/HC is high during the idling.13
Charging performanceBattery run downThe battery is soon rundown.
Or, the charging ability of battery is small.
14
Cooling performanceOverheatingThe temperature of engine cooling water is extremely high.15
AS&G systemStarting impossible (starter not operative) Although the key or the engine is operated, the engine cannot be started.16
AS&G OFF display screen is not turned ON right after the ignition switch is turned to the ON position17
Although AS&G OFF switch pressed, AS&G system not switchedAlthough the AS&G OFF switch is pressed, the AS&G system is not switched to ON/OFF.18
AS&G system abnormal (auto stop not carried out)Although the auto stop requirements are satisfied, the auto stop cannot be carried out.19 <M/T>,
<CVT>
AS&G system abnormal (auto start not carried out)
  • Although the auto stop requirements are satisfied, the auto stop cannot be carried out. <M/T>
  • Although the brake pedal is not depressed, the auto start cannot be carried out. <CVT>
20
AS&G system abnormal (auto start carried out under condition that clutch pedal not operated) <M/T>Although the clutch pedal is depressed, the auto start cannot be carried out.21
AS&G system abnormal (auto start carried out under condition that brake pedal is operated) <CVT>Although the brake pedal is depressed, the auto start is carried out.22
Audio equipment is reset or sound jump occurs at auto start23Refer to GROUP 54A - DC/DC converter - Symptom Procedures .
