(a) Remove the AM2 fuse from the engine room junction block.
(b) Remove the GAUGE, FR DOOR and ECU-IG fuses from the driver side junction block.
(c) Measure the resistance of the fuses.
Standard resistance:
Below 1 Ohms
NG -- REPLACE FUSE
OK -- Continue to next step.

2. INSPECT IG1 RELAY




(a) Remove the IG1 relay from the driver side junction block.
(b) Measure the resistance of the relay.
Standard resistance:






NG -- REPLACE IG1 RELAY
OK -- Continue to next step.

3. CHECK WIRE HARNESS (MASTER SWITCH - BATTERY AND BODY GROUND)




(a) Disconnect the P17 switch connector.
(b) Measure the voltage or resistance of the wire harness side connector.
Standard voltage:






Standard resistance:






OK -- REPLACE POWER WINDOW REGULATOR MASTER SWITCH ASSEMBLY
NG -- Continue to next step.

4. CHECK WIRE HARNESS (MASTER SWITCH - JUNCTION BLOCK)




(a) Disconnect the P17 switch connector.
(b) Disconnect the 1G and 1H junction block connectors.
