PARK ASSIST / MONITORING: ADVANCED PARKING GUIDANCE SYSTEM: C1628: Vehicle Height Sensor Failure
C1628 - Vehicle Height Sensor Failure

DESCRIPTION

The rear height control sensor sub-assembly RH is connected to the parking assist ECU. This DTC is stored when the parking assist ECU judges that vehicle height sensor signal received from the rear height control sensor sub-assembly RH is abnormal or has not changed (rear height control sensor sub-assembly RH seized).

INSPECTION PROCEDURE

NOTICE:
* When the "System initializing" message is displayed on the navigation computer sub-assembly after the auxiliary battery cable has been disconnected, correct the steering angle neutral point Initialization.
* Depending on the parts that are replaced or operations that are performed during vehicle inspection or maintenance, calibration of other systems as well as the advanced parking guidance system may be needed Calibration.

PROCEDURE

1. CHECK VEHICLE SPECIFICATION

(a) Check vehicle specification.

Result:





B -- CHECK HARNESS AND CONNECTOR (PARKING ASSIST ECU - REAR HEIGHT CONTROL SENSOR SUB-ASSEMBLY)
A -- Continue to next step.

2. CHECK HARNESS AND CONNECTOR (PARKING ASSIST ECU - REAR HEIGHT CONTROL SENSOR SUB-ASSEMBLY)

(a) Disconnect the L65 connector from the parking assist ECU.

(b) Disconnect the S3 connector from the rear height control sensor sub-assembly RH.

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

Standard Resistance:





Result:





B -- CHECK REAR HEIGHT CONTROL SENSOR SUB-ASSEMBLY RH

A -- REPAIR OR REPLACE HARNESS OR CONNECTOR

3. CHECK HARNESS AND CONNECTOR (PARKING ASSIST ECU - REAR HEIGHT CONTROL SENSOR SUB-ASSEMBLY)

(a) Disconnect the L65 connector from the parking assist ECU.

(b) Disconnect the S3 connector from the rear height control sensor sub-assembly RH.

(c) 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. CHECK REAR HEIGHT CONTROL SENSOR SUB-ASSEMBLY RH

(a) Reconnect the L65 connector to the parking assist ECU.

(b) Disconnect the S3 connector from the rear height control sensor sub-assembly RH.

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





Standard Voltage:
