Disconnect Connector C16 from CJB.
1
Measure the resistance between the control panel
2
for the climate control system, connector C380, pin
8, circuit 29-FA13 (OG), wiring harness side and
the CJB, connector C16, pin 9, circuit 29-FA13
(OG), wiring harness side.

Yes
CHECK the CJB and RENEW as necessary. CHECK
the operation of the system.
No
LOCATE and RECTIFY the break in circuit 29-FA13
(OG) between the control panel for the climate
control system and the CJB using the Wiring
Diagrams. CHECK the operation of the system.
