PINPOINT TEST G531332p31 : "FLIGHT RECORDER" DATA IS STORED IF ANY ONE OF FIVE CONDITIONS OCCUR

G531332t148 : CHECK THE INERTIA SWITCH TO ECM CIRCUIT FOR SHORT CIRCUIT TO POWER VOLTAGE
1. Make sure the inertia switch is not tripped.
2. Disconnect the inertia switch electrical connector, CR02.
3. Disconnect the ECM electrical connector, EC300.
4. Measure the voltage between:

Inertia switch connector ECM connector EC300,
CR02, harness side harness side
Pin 03 Pin 42

- Is the voltage greater than 3 volts?

-> YES
REPAIR the short circuit. CLEAR the DTC. TEST the system for normal operation.

-> NO
INSTALL a new inertia switch. CLEAR the DTC. CLEAR the flight recorder information. TEST the system for normal operation.
