Breakout box and checking ground terminals

Is the breakout box connected? Have the ground terminals been checked?

1. YES Refer to «Checking the voltage for the outside temperature sensor»(ref-441376-S32776268122011121500000)
2. NO Refer to «Areas of use for the breakout box»(ref-441376-S20679460852011121500000)

Areas of use for the breakout box

Breakout box 9813190 is designed to facilitate reading off

1. the control module input and output signals when the control module is connected
2. the resistance of cables and components with the control module disconnected.

The breakout box makes it safer to take readings because it is easier to see and access measurement points. The risk of accidental short-circuits and damaged connector pins is also reduced.

Turn off the power to the ECC control module when connecting the breakout box otherwise the control module may be damaged and incorrect diagnostic trouble codes (DTCs) stored.
