1. REMOVE VISCOUS HEATER RELAY

Remove the viscous heater relay from the engine room relay block.

2. INSPECT VISCOUS HEATER RELAY

Measure the resistance of the viscous heater relay.

Standard Resistance:
Tester Connection Condition Specified Condition
3 - 5 Battery voltage not applied between terminals 1 and 2 10 kΩ or higher
Battery voltage applied to terminal 1 and 2 Below 1 Ω

If the result is not as specified, replace the relay.

3. INSTALL VISCOUS HEATER RELAY

Install the viscous heater relay to the engine room relay block.

Tester Connection	Condition	Specified Condition
3 - 5	Battery voltage not applied between terminals 1 and 2	10 kΩ or higher
