Corrective actions

Heater error

1. Check the connections of the Heater connectors.

- Reconnect the Heater connectors.

2. Check the resistance between both ends of the Heater.

: Check the resistance between both ends of the Heater directly, or check

the resistance between the red wire of the Heater Relay and the amber

and yellow wires of the Power Relay, respectively.

Normal: Approx. 13Ω

➢



Check after disconnect circuit breaker or power cable.

- Faulty: Replace the Heater.

3. Check the connections of the Heater Relay.

: Check the voltage between the red wire of the Heater Relay on the base

and the yellow and amber wires of the Power Relay.

Normal: 120V (while operating)

➢

- Reconnect the Heater Relay connectors.

Heater Relay

red wire

connector

Power Relay

amber

wire connector

4. Check the driving signals for the Heater Relay.

- Measure the voltage between pin 6 (amber) of the Main PBA CN7

connector and pin 2 (red) of the CN7 connector.
When the Heater is off: 10.5 to 13V

➢

When the Heater is operating: < 0.5V

➢

New PBA

4-1.Check the driving signals for the Heater Relay.

- Measure the voltage between pin 6 (amber) of the Main PBA CN302

connector and pin 2 (red) of the CN302 connector.
When the Heater is off: 9.5 to 13V

➢

When the Heater is operating: < 0.5V

➢

- Faulty: Replace the Main PBA assy.

- Normal: Replace the Heater Relay.
