Diagnostic Procedure with Diagnostic Trouble Code (DTC)
Step
1 CHECK HARNESS.
1) Disconnect the body integrated module
connector.
2) Measure the resistance between body inte-
grated module connector and chassis ground.
Connector & terminal
(B280) No. 6 — Chassis ground:
2 CHECK HARNESS.
1) Disconnect the body integrated module
connector.
2) Disconnect the shift lock solenoid connec-
tor.
3) Measure the resistance between body inte-
grated module connector and shift lock sole-
noid connector.
Connector & terminal
(B280) No. 6 — (B116) No. 3:
3 CHECK SHIFT LOCK SOLENOID.
1) Disconnect the shift lock solenoid connec-
tor.
2) Measure the internal resistance of shift lock
solenoid.
Connector & terminal
(B116) No. 3 — No. 4:
4 CHECK GROUND CIRCUIT.
1) Disconnect the shift lock solenoid connec-
tor.
2) Measure the resistance between shift lock
solenoid connector and chassis ground.
Connector & terminal
(B116) No. 4 — Chassis ground:
5 CHECK HARNESS.
1) Disconnect both the body integrated mod-
ule connector and shift lock solenoid connector
(B116).
2) Measure the resistance between body inte-
grated module connector and chassis ground.
Connector & terminal
(B280) No. 6 — Chassis ground:
Check
Is the resistance 10 — 30 Ω?
Is the resistance less than 10
Ω?
Is the resistance 10 — 30 Ω?
Is the resistance less than 10
Ω?
Is the resistance more than 1
MΩ?
