Checking the glow plug resistor (ZS-T)
Using an ohmmeter, check for continuity between the resistor terminals.
- Resistance at 20°C - 0.65 ohm
If there is no continuity, replace the resistor.
Checking the coolant temperature sensor (ZS-T)
1. Check the continuity between the sensor leads.
Resistance:
- at 20°C - 2-3 kOhm
- at 80°C - 0.2 - 0.3 kOhm
Checking the glow plug relay (ZS-T)
1. Check continuity between relay outputs.
Resistance at 20°C:
- "g" And "e" - 52.2 - 80.0 ohms
- "+V" And "G" - infinity
2. Apply battery voltage to terminals "g" And "e", check for continuity between terminals "+V" And "G".
Checking the starter relay (ZS-T)
1. Check continuity between relay outputs.
Resistance:
- "1" And "2" - 50-90 Ohm
- "3" And "5" - infinity
2. Apply battery voltage to terminals "1" And "2", check for continuity between terminals "3" And "5".
