Direction indicators
Direction indicators |
1. |
If only a single lamp is faulty,
first check the bulb and its connector.
|
2. |
If
none
of the direction indicator lamps work,
check the direction indicator lamp fuses in the main fuse box in the dashboard.
|
3. |
Plug in the scan tool and select "READ FAULT CODES" from the menu. If any
trouble codes are present, continue on page
.
|
5. |
Check the grounding of the direction indicator lamps for continuity/shorting
by taking readings of the wiring as follows:
|
• |
between pin 3 of the connector for the front direction
indicator lamps and a good grounding point.
|
• |
between one of the side direction indicator connectors (black lead) and a good
grounding point.
|
• |
between pins 4 (left-hand) and 2 (right-hand) of the rear direction indicator lamp
connectors and a good grounding point.
|
6. |
Activate the direction indicator switch and check the power supply to the
direction indicator lamps by taking readings as follows:
|
• |
between pin 2 of the connector for the front direction
indicator lamps and a good grounding point.
|
• |
between pins 2 (left-hand) and 4 (right-hand) of the rear direction indicator lamp
connectors and a good grounding point.
The voltage readings should change between 0 V and 12 V. |
7. |
If they do not, check the wiring for continuity/shorting as follows between ICE
module connector pins 1 (left-hand) and 48 (right-hand) and:
|
• |
pin 2 of the connector for the front direction indicator
lamps.
|
• |
the connector for the side direction indicators (yellow/black (LH) and
green/black (RH) leads).
|
• |
pins 2 (left-hand) and 4 (right-hand) of the connector for the rear direction
indicator lamps.
|
10. |
If they do not work, check the leads for continuity/shorting by taking
resistance readings as follows:
|
• |
across pin 18 of the ICE control module connector
and pin 4 of the direction indicator switch connector.
|
• |
across pin 19 of the ICE control module connector and pin 2 of the direction
indicator switch connector.
