Is measure voltage within Specification?
YES
- Go to "SIGNAL CIRCUIT INSPECTION " procedure.
NO
- Short circuit to chassis ground between Acceleration sensor harness connector and reference voltage.
- Open circuit between Acceleration sensor harness connector and PCM connector.
- Repair as necessary and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
NOTE:
In case, when acceleration sensor connector is disconnected, the voltage at terminal 1 is 0V.
- Possible cause: Open or short circuit in harness between terminal 32 of PCM and terminal 1 of acceleration sensor or PCM
