Parts Involved
How to Fix
- 1
1. Check if Main PCB Connector CN30 is inserted correctly
- 2
2. Check if F DEF Sensor unit is normal by measuring resistance at CN30 #6 to #8 — compare with temperature table
- 3
3. Measure voltage between Main PCB Connector CN30-#6 (Pink) and REG1 Heat Sink — should be between 0.6V and 4.6V
- 4
4. Check input voltage of IC10 MICOM #58 — should match CN30-#6 voltage
- 5
5. If all normal, recheck bad contact of connector
