Diagnosis - Diagnosis-fault diagnosis of electronic and electrical parts DI - 81

Standard: IN

Multimeter connection Standard value
DI
85-86 Conduction

30-87 No breakdown
EG
Check if the result is ok?
Yes>go to Step 3. TR
NO>replace the fuse or relay.

3. Check the preheating circuit. AX

a. Adopt a multimeter to separately measure the resistance between #30 hole seat of preheating relay R01 and
preheating fuse GF\L3 or between #87 hole seat and preheater F019.
FR
Standard resistance:

Multimeter connection Standard value ST

R01(30)-GF\L2
About 0Ω
BR
R01(87)-F019

Check if the result is ok?
BW
Yes>go to Step 4.

No>repair the relevant harness.
EL
4. Check the pre-heater

a. Adopt a multimeter to measure the resistance between both ends of preheater.

Standard resistance:

Multimeter connection Standard value

Two ends of pre-heater About 7Ω

Check if the result is ok?
Yes>go to Step 5.
NO>replace the pre-heater

5. Check the crankshaft/cam shaft position sensor and relevant circuit

a. Check the crankshaft position sensor(Refer to “Chapter DI Diagnosis-Diagnosis of Engine Electric Control
Fault-Fault of Crankshaft Position Sensor”)

b. Check the camshaft position sensor (refer to Chapter DI diagnosis- engine electronic control fault
diagnosis–camshaft position sensor failure)
Check if the result is ok?

Yes>go to Step 6.
No>replace relevant fault sensor or faulty harness.
