INSPECTION PROCEDURE 1. INSPECT SHIFT LOCK CONTROL ECU
HINT: If
the results of the following inspections are as specified but a
malfunction has occurred, replace the shift lock control unit assembly. (a) Inspect wire harness:
| (1) Disconnect the shift lock control ECU connector. | |
| (2) Measure the voltage according to the value(s) in the table below.
Standard Voltage: |
Tester Connection | Condition |
Specified Condition | |
5 (IG) - Body ground |
Power switch on (IG) |
11 to 14 V | |
Power switch off |
Below 1 V | If the result is not as specified, repair or replace the shift lock control ECU wire harness. |
