REAR SUNSHADE SYSTEM - Rear Sunshade does not Operate with Rear Sunshade Switch

Remove the LH-IG fuse from the cowl side junction block LH.

Measure the resistance of the fuses.

• Standard resistance:
• Below 1 Ω

Disconnect the Q24 relay connector.

Disconnect the Q2 cowl side junction block LH connector.

Disconnect the J12 rear sunshade switch connector.

Measure the resistance of the wire harness side connectors.

• Standard resistance:

• Tester Connection	Specified Condition
  REV (Q24-2) - OP02 (Q2-20)	Below 1 Ω
  SW (Q24-3) - J12-3	Below 1 Ω
  E (Q24-5) - Body ground	Below 1 Ω
  REV (Q24-2) - E (Q24-5)	10 kΩ or higher
  SW (Q24-3) - E (Q24-5)	10 kΩ or higher

Turn the engine switch on (IG).

Measure the voltage of the wire harness side connector.

• Standard voltage:

• Tester Connection	Specified Condition
  IG (Q24-1) - Body ground	10 to 14 V

Disconnect the connector from the rear sunshade switch.

Measure the resistance between the terminals according to the value(s) in the table below.

• Standard resistance:

• Tester connection	Condition	Specified condition
  J12-3 (ECU) - J12-4 (E)	Rear sunshade switch is pressed	Below 1 Ω
