Starting conditions, auxiliary heater
| Starting conditions, auxiliary heater |
| Starting conditions 1 and 2 |
The input for starting conditions 1 and 2 is supplied via relay 409a which in turn is controlled by SID which, based on the outside temperature, decides if the heater is permitted to start.
| Diagnostics |
If power is missing on the input for starting condition 1 when the input for starting condition 2 is supplied with power, diagnostic trouble code B0487 is generated.
