12.CHECKING OF ENGINE SPEED SIGNAL(ESS)CIRCUIT
Fault code number is displayed by MIL
CHECKING CIRCUIT
Coupler terminal is based on the side of Wire-Harness.
CHECK PROCEDURE
1) Turn off the ignition key .
2) Check the ESS coupler is loose, or bad.
If there is no problem, check the resistance of tachometer.
3) Check the resistance between each terminals and ground.
Measuring terminal: B electric wire ~ EARTH, ECU NO. 32 (B/Y:BLACK/YELLOW)
~ EARTH
The resistance between each terminals and ground :
∞
[ ]
If the measured resistance value is abnormal, replace the part with new one.
Refer to ( ) for assembly and disassembly
Remark : Measuring unit of voltage : Resistance [ ]
4) If the measured resistance and continuity are abnormal,
. Replace the tachometer with new one, and it rechecks.
5) If the resistance and continuity are normal, contact the tachometer coupler.
