Step
9 CHECK HARNESS BETWEEN BODY INTE-
GRATED UNIT AND "P" RANGE SWITCH.
1) Disconnect the connector of the "P" range
switch.
2) Measure the resistance of harness
between body integrated unit and the "P" range
switch.

(B116) No. 1 — (B281) No. 13:
10 CHECK HARNESS BETWEEN "P" RANGE
SWITCH AND CHASSIS GROUND.
Measure the resistance of harness between
"P" range switch and chassis ground.
Connector & terminal
(B116) No. 2 — Chassis ground:
11 CHECK "P" RANGE SWITCH.
1) Shift the select lever to the "P" range.
2) Measure the resistance between "P" range
switch connector terminals.
Terminals
No. 2 — No. 1:
12 CHECK "P" RANGE SWITCH.
1) Shift the select lever to other than "P"
range.
2) Measure the resistance between "P" range
switch connector terminals.
Terminals
No. 2 — No. 1:
13 CHECK BACKUP POWER SUPPLY CIR-
CUIT.
Inspect the backup power supply circuit.

14 CHECK TEST MODE CONNECTOR.
1) Check that the test mode connector is dis-
connected.
2) Measure the resistance between the body
integrated unit and chassis ground.
Connector & terminal
(i84) No. 3 — Chassis ground:
15 CHECK OPERATION.
1) Connect all the connectors.
2) Operate the key lock solenoid.
