PINPOINT TEST E

Pinpoint Tests

NOTE: Use a digital multimeter for all electrical measurements.

PINPOINT TEST E : THE POWER SEAT DOES NOT RECLINE - HIGH SPECIFICATION SEAT ONLY

E1 : CHECK THE LH FRONT SEAT BACKREST MOTOR FOR CORRECT OPERATION
1. Operate the LH seat control switch to the REARWARD RECLINE position.

- Is the LH seat recline adjustment inoperative?

-> YES
GO to Pinpoint Test E2.

-> NO
GO to Pinpoint Test E6.

E2 : CHECK THE LH FRONT SEAT BACKREST MOTOR CIRCUITS
1. Disconnect the seat backrest motor electrical connector LS6.
2. Operate the seat control switch to the REARWARD RECLINE position.
3. Measure the voltage between the seat backrest motor electrical connector LS6 pin 2, (WR), and LS6 pin 1, (YR).

- Is the voltage greater than 10 volts?

-> YES
INSTALL a new seat backrest motor.

-> NO
GO to Pinpoint Test E3.

E3 : CHECK THE LH FRONT SEAT BACKREST MOTOR CIRCUIT
1. Operate the seat control switch to the REARWARD RECLINE position.
2. Measure the voltage between the seat backrest motor electrical connector LS6 pin 2, (WR), and ground.

- Is the voltage greater than 10 volts?

-> YES
GO to Pinpoint Test E4.

-> NO
GO to Pinpoint Test E5.

E4 : CHECK THE LH FRONT SEAT BACKREST MOTOR CIRCUIT FOR OPEN
1. Disconnect the seat control switch electrical connector LS1.
2. Measure the resistance between the seat backrest motor electrical connector LS6 pin 1, (YR), and the seat control switch electrical connector LS1 pin 7, (YR).

- Is the resistance less than 5 Ohms?

-> YES
INSTALL a new seat control switch.

-> NO
REPAIR the circuit. TEST the system for normal operation.

E5 : CHECK THE LH FRONT SEAT BACKREST MOTOR CIRCUIT FOR OPEN
1. Disconnect the seat control switch electrical connector LS1.
2. Measure the resistance between the seat backrest motor electrical connector LS6 pin 2, (WR), and the seat control switch electrical connector LS1 pin 12, (WR).

- Is the resistance less than 5 Ohms?

-> YES
INSTALL a new seat control switch.

-> NO
REPAIR the circuit. TEST the system for normal operation.

E6 : CHECK THE RH FRONT SEAT BACKREST MOTOR CIRCUITS
1. Disconnect the seat backrest motor electrical connector RS6.
2. Operate the seat control switch to the REARWARD RECLINE position.
3. Measure the voltage between the seat backrest motor electrical connector RS6 pin 2, (YR), and RS6 pin 1, (WR).

- Is the voltage greater than 10 volts?

-> YES
INSTALL a new seat backrest motor.

-> NO
GO to Pinpoint Test E7.

E7 : CHECK THE RH FRONT SEAT BACKREST MOTOR CIRCUIT
1. Operate the seat control switch to the REARWARD RECLINE position.
2. Measure the voltage between the seat backrest motor electrical connector RS6 pin 2, (YR), and ground.

- Is the voltage greater than 10 volts?

-> YES
GO to Pinpoint Test E8.

-> NO
GO to Pinpoint Test E9.

E8 : CHECK THE RH FRONT SEAT BACKREST MOTOR CIRCUIT FOR OPEN
1. Disconnect the seat control switch electrical connector RS1.
2. Measure the resistance between the seat backrest motor electrical connector RS6 pin 1, (WR), and the seat control switch electrical connector RS1 pin 7, (WR).

- Is the resistance less than 5 Ohms?

-> YES
INSTALL a new seat control switch.

-> NO
REPAIR the circuit. TEST the system for normal operation.

E9 : CHECK THE RH FRONT SEAT BACKREST MOTOR CIRCUIT FOR OPEN
1. Disconnect the seat control switch electrical connector RS1.
2. Measure the resistance between the seat backrest motor electrical connector RS6 pin 2, (YR), and the seat control switch electrical connector RS1 pin 12, (YR).

- Is the resistance less than 5 Ohms?

-> YES
INSTALL a new seat control switch.

-> NO
REPAIR the circuit. TEST the system for normal operation.
