Pinout Values and Diagnostic Parameters

MIRROR (EXT): POWER MIRROR CONTROL SYSTEM: TERMINALS OF ECU

1. CHECK AIR CONDITIONING AMPLIFIER ASSEMBLY

(a) Disconnect the L17 air conditioning amplifier assembly connector.





(b) Measure the voltage and resistance according to the value(s) in the table below.

HINT
Measure the values on the wire harness side with the connector disconnected.





If the result is not as specified, there may be a malfunction in the wire harness.

(c) Reconnect the L17 air conditioning amplifier assembly connector.

(d) Measure the voltage according to the value(s) in the table below.





If the result is not as specified, the air conditioning amplifier assembly may have a malfunction.

2. CHECK AIR CONDITIONING CONTROL ASSEMBLY (CENTER CLUSTER MODULE CIRCUIT)

(a) Disconnect the L20 air conditioning control assembly (center cluster module circuit) connector.





(b) Measure the voltage and resistance according to the value(s) in the table below.

HINT
Measure the values on the wire harness side with the connector disconnected.





If the result is not as specified, there may be a malfunction in the wire harness.

(c) Reconnect the L20 air conditioning control assembly (center cluster module circuit) connector.

(d) Check for pulses according to the value(s) in the table below.





If the result is not as specified, the air conditioning control assembly (center cluster module circuit) may have a malfunction.
