TROUBLE SHOOTING

If  there  are  any  failure  with  this  instrument,  check  the  following  trouble  shoots  before  asking 
repair service. Ask KAISE AUTHORIZED SERVICE AGENCY through your local dealer when there 
are any questions or troubles with this instrument. 

●

 Batteries are exhausted.

 

→

 Replace the batteries.

●

 Batteries are installed in the wrong polarity.

 

→

 Install the batteries in the correct polarity.

●

 Pressing time of the POWER Key is too short or not enough.

 

→

 Press POWER Key for 1 second or more.

Symptoms

Possible Causes and Necessary Treatments

Cannot turn on

the instrument

●

 The temperature of the O2 sensor is cooler than the certain temperature.

 

→

 Warm up the O2 sensor keeping constant engine speed at approx. 

        2,500rpm for 3 or 4 minutes. Keep the engine speed at approx. 2,500rpm
        during the normal test.

Displayed value

is unstable

●

 Test lead or check harness are broken.

 

→

 Inspect whether they are disconnected. (see page 18 to 20)

●

 O2 sensor or the other parts are broken.

 

→

 Make the same test with the other cars and check if the display still have

        the failure.

LCD does not display
