DETAILS/RESULTS/ACTIONS
2 Measure the voltage between heater control
module, connector C28, pin 1, circuit 8-GB10A
(WH/BK), harness side and ground.
• Is the indicated voltage between 5 and 9 volts?
Yes
GO TO A12
No
REPAIR the open circuit(s) between instru-
ment cluster and heater control module by
using the wiring diagrams. TEST the system
for normal operation. If the concern is not
rectified REFER to Section 413-01.
2 Measure the resistance between heater control
solenoid valve, connector C49, pin 2, circuit
31S-CA82 (BK/GN), harness side and heater
control solenoid valve, connector C28, pin 5,
circuit 31S-CA82 (BK/GN), harness side.
• Is the resistance less than 2 ohms?
Yes
GO TO A13
No
REPAIR the open circuit(s) between heater
control solenoid valve and heater control
module by using the wiring diagrams. TEST
the system for normal operation.
1 Measure the resistance between heater control
module, connector C28, pin 6, circuit 91-CA83
(BK/RD), harness side and ground.
• Is the resistance less than 2 ohms?
Yes
CHECK the heater control module and
INSTALL a new one if necessary. TEST the
system for normal operation.
No
REPAIR the open circuit(s) between heater
control module and ground G5 by using the
wiring diagrams. TEST the system for nor-
mal operation.
