1. Ignition OFF, disconnect the harness connector at the appropriate B88 seat position sensor.
2. Test for less than 10 ohm between the low reference circuit terminal 1 and ground.
瀚慖f greater than the specified range, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the K36
SDM.
3. Ignition ON, test for 4-9 V between the signal circuit terminal 2 and ground.
瀚慖f less than the specified value, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace
the K36 SDM.
瀚慖f greater than the specified range, test the signal circuit for a short to voltage. If the circuit tests normal, replace the K36 SDM.
4. If all circuits test normal, replace the B88 seat position sensor.
