INSPECTION PROCEDURE

PROCEDURE

1. CHECK FUSE (P-IG-4, P S/HTR, D-IG1-3)
(a) Remove the P-IG-4 and P S/HTR fuses from the passenger side junction block.
(b) Remove the D-IG1-3 fuse from the main body ECU.
(c) Measure the resistance of the fuses.
Standard resistance:

NG -- REPLACE FUSE
OK -- Continue to next step.

2. CHECK HARNESS AND CONNECTOR (SEAT CLIMATE CONTROL ECU - BATTERY AND BODY GROUND)

(a) Disconnect the e4 ECU connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.

3. CHECK HARNESS AND CONNECTOR (SEAT CLIMATE SWITCH RH - BATTERY AND BODY GROUND)

(a) Disconnect the L68 switch connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.

4. INSPECT CLIMATE CONTROL SWITCH RH

(a) Remove the L68 switch connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:

NG -- REPLACE CLIMATE CONTROL SWITCH RH
OK -- Continue to next step.

5. CHECK HARNESS AND CONNECTOR (SEAT CLIMATE CONTROL ECU - SEAT CLIMATE SWITCH RH AND BODY GROUND)

(a) Disconnect the e4 ECU connector.
(b) Disconnect the L68 switch connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard resistance:

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- REPLACE SEAT CLIMATE CONTROL ECU
