Self-Diagnosis - SSANGYONG 1999 Musso Service Manual

SELF-DIAGNOSIS

ECS-ECU indicates ECS circuit defectives to the driver by flickering ECS indicator lamp in the meter cluster 0.5
second of interval if there are defectives.

1. Turn the ignition switch ON and if ECS system is normal, ECS indicator lamp will turn on for 3 seconds and then go
off. However if defective, ECS indicator lamp will flicker in the interval of 0.5 second continuously.
2. Identify fault code with Scanner.
Judging Conditions
When sensor output
voltage is less than
0.5-4.5V, more than
4.5V.
When sensor output
voltage is less than
0.55±0.15V, more than
4.45±0.1V.
When sensor output
voltage is less than
0.5-4.5V, more than
4.5V.
Check step motor
power supply detecting
circuit for open and
short.
check for relative
connectors.
When defective detect-
ing circuit has detected
defectives during
output OFF.
When ECU does not
work normally.
