NAVIGATION SYSTEM (for HDD) - Steering Pad Switch Circuit |
DESCRIPTION
This circuit sends an operation signal from the steering pad switch to the navigation receiver assembly.If there is an open in the circuit, the audio system cannot be operated using the steering pad switch.If there is a short in the circuit, the same condition as when a switch is continuously depressed occurs.Therefore, the navigation receiver assembly cannot be operated using the steering pad switch and the navigation receiver assembly itself cannot function.

INSPECTION PROCEDURE
- CAUTION:
- The vehicle is equipped with an SRS (Supplemental Restraint System) which includes components such as airbags. Before servicing (including removal or installation of parts), be sure to read the Precaution in the Supplemental Restraint System (RAV4_ACA30 RM000000KT106QX.html).
| 1.INSPECT STEERING PAD SWITCH ASSEMBLY |
Remove the steering pad switch assembly (RAV4_ACA30 RM000001H7K00HX.html).
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection
| Switch Condition
| Specified Condition
|
10 (AU1) - 8 (EAU)
| No switch is pushed
| 95 to 105 kΩ
|
Seek+ switch is pushed
| Below 2.5 Ω
|
Seek- switch is pushed
| 312 to 345 Ω
|
Volume+ switch is pushed
| 950 to 1050 Ω
|
Volume- switch is pushed
| 2954 to 3265 Ω
|
9 (AU2) - 8 (EAU)
| No switch is pushed
| 95 to 105 kΩ
|
MODE switch is pushed
| Below 2.5 Ω
|
On Hook switch is pushed
| 312 to 345 Ω
|
Off Hook switch is pushed
| 950 to 1050 Ω
|
Voice switch is pushed
| 2954 to 3265 Ω
|
| 2.INSPECT SPIRAL CABLE SUB-ASSEMBLY |
Remove the spiral cable sub-assembly (RAV4_ACA30 RM000001DNS00EX.html).
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection
| Condition
| Specified Condition
|
8 (EAU) - 4 (EAU)
| Spiral cable is turned 2.5 rotations counterclockwise
| Below 1 Ω
|
Spiral cable is centered
|
Spiral cable is turned 2.5 rotations clockwise
|
10 (AU1) - 6 (AU1)
| Spiral cable is turned 2.5 rotations counterclockwise
|
Spiral cable is centered
|
Spiral cable is turned 2.5 rotations clockwise
|
9 (AU2) - 5 (AU2)
| Spiral cable is turned 2.5 rotations counterclockwise
|
Spiral cable is centered
|
Spiral cable is turned 2.5 rotations clockwise
|
- CAUTION:
- The spiral cable is an important part of the SRS airbag system. Incorrect removal or installation of the spiral cable may prevent the airbag from deploying. Be sure to read the Precaution for the SRS (RAV4_ACA30 RM000000KT106QX.html).
| 3.CHECK HARNESS AND CONNECTOR (NAVIGATION RECEIVER - SPIRAL CABLE) |
Disconnect the E106 navigation receiver connector.
Disconnect the E10 spiral cable connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection
| Condition
| Specified Condition
|
E106-7 (SW1) - E10-6 (AU1)
| Always
| Below 1 Ω
|
E106-8 (SW2) - E10-5 (AU2)
|
E106-6 (SWG) - E10-4 (EAU)
|
E106-7 (SW1) - Body ground
| Always
| 10 kΩ or higher
|
E106-8 (SW2) - Body ground
|
E106-6 (SWG) - Body ground
|
| | REPAIR OR REPLACE HARNESS OR CONNECTOR |
