STEERING SHIFT SWITCH INSPECTION

BHE051446102W05

1. Remove the driver-side air bag module. (See DRIVER-SIDE AIR BAG MODULE REMOVAL/INSTALLATION.)

2. Connect the connector to the steering shift switch.

3. Connect the negative battery cable.

4. Measure the voltage at the steering shift switch.

  • When inspecting terminal C for continuity, disconnect the steering shift switch connector.

5. If the value are not as specified in the Terminal Voltage List (Reference), inspect the parts under "Action" and related wiring harnesses.

6. If the parts inspected under "ACTION" are found to be normal but the system still does not operate normally, replace the up or down switch according to the following conditions:

  • The voltage is normal when the up switch is on and is abnormal when the down switch is on: Replace the down switch.
  • The voltage is normal when the down switch is on and is abnormal when the up switch is on: Replace the up switch.

## Terminal Voltage List (Reference)

Terminal | Signal | Connected to | Test condition | Voltage (V)/ Continuity | Action
--- | --- | --- | --- | --- | ---
C | Steering shift switch ground | GND | Under any condition: inspect for continuity to ground | Yes | • Inspect GND
D | TNS | • Clock spring • Headlight switch | Headlight switch TNS or on | B+ | • Inspect clock spring • Inspect headlight switch • Inspect related harness
Headlight switch off | Below 1.0
F | Shift change signal | • Clock spring • TCM | M range | Up switch and down switch off | 3.96 | • Inspect clock spring • Inspect TCM • Inspect related harness
Up switch on | 1.95
Down switch on | 2.48
Up switch and down switch on | 1.50
