PROCEDURE
| 1. | CHECK HARNESS AND CONNECTOR (STEERING SENSOR POWER SOURCE) |
(a) Disconnect the G62 steering sensor connector.
(b) Measure the voltage according to the value(s) in the table below.
Standard Voltage:
| Tester Connection | Condition | Specified Condition |
|---|---|---|
| G62-9 (IG1) - G62-6 (ESS) | Power switch on (IG) | 11 to 14 V |
| NG |  | REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
| 2. | CHECK HARNESS AND CONNECTOR (STEERING SENSOR POWER SOURCE) |
(a) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
| Tester Connection | Condition | Specified Condition |
|---|---|---|
| G62-6 (ESS) - Body ground | Always | Below 1 Ω |
(b) Measure the voltage according to the value(s) in the table below.
Standard Voltage:
