TROUBLE DIAGNOSES — Main Power Supply and Ground Circuit Check (Cont'd) — Push Control Unit Check

HA-66prose procedure

Connector M40 = push control unit; pin 14 = L/OR power feed; pin 17 = B ground (Black). Continuity table omitted on this page (matches the implicit 'Yes' criterion shown for HA-65 ground check).

Main Power Supply and Ground Circuit Check (Cont'd)

PUSH CONTROL UNIT CHECK

Power-supply circuit check (with ignition switch at ACC)

1
Disconnect push control unit harness connector.
2
Connect voltmeter from harness side.
3
Measure voltage across terminal No. 14 and body ground.

Voltmeter readings — terminal 14 vs body ground

Voltmeter terminal (+)	Voltmeter terminal (−)	Voltage
14	Body ground	Approx. 12V

Voltmeter terminal (−)Body ground

VoltageApprox. 12V

Body-ground circuit check (with ignition switch OFF)

1
Disconnect push control unit harness connector.
2
Connect ohmmeter from harness side.
3
Check for continuity between terminal No. 17 and body ground.
