Turn Signal/Hazard Warning Lights (Body Control Module) Input Test

NOTE:

Make sure the fuses associated with the system is OK.
If you are troubleshooting multiple DTCs, be sure to follow the instructions in B-CAN System Diagnosis Test Mode A .

1. Turn the vehicle to the OFF (LOCK) mode.

2. Disconnect body control module connectors.

Inspect the connectors and socket terminals to be sure they are all making good contact:

If the terminals are bent, loose, or corroded, repair them as necessary, and recheck the system.
If the terminals are OK, go to step 4.

Reconnect the connectors to the body control module, do the following input tests:

If any test indicates a problem, find and correct the cause, then recheck the system.
If all the input tests prove OK, go to step 5.

Cavity	Wire	Test condition	Test: Desired result	Possible cause if desired result is not obtained
A1	RED	Under all conditions	Measure the voltage to ground:There should be battery voltage.	An open or high resistance in the wire
C27	WHT	Under all conditions	Measure the voltage to ground:There should be battery voltage.	An open or high resistance in the wire
E1	BLU	Vehicle ON mode	Measure the voltage to ground:There should be battery voltage.	An open or high resistance in the wire
A2	BLK	In all power modes	Measure the voltage to ground:There should be less than 0.2 V.	Poor ground (G401) An open or high resistance in the ground wire
A8	BLK	In all power modes	Measure the voltage to ground:There should be less than 0.2 V.	Poor ground (G401) An open or high resistance in the ground wire
C2	GRN	Hazard warning switch pressed	Measure the voltage to ground:There should be less than 0.2 V.	Faulty hazard warning switch Poor ground (G402) An open or high resistance in the ground wire
C2	GRN	Hazard warning switch released	Measure the voltage to ground:There should be battery voltage.	Faulty hazard warning switch A short to ground in the wire
E6*C3	LT GRN*BLK	Turn signal switch in left position	Measure the voltage between terminals E6 and C3:There should be less than 0.2 V.	Faulty turn signal switch An open or high resistance in the wire
E6*C3	LT GRN*BLK	Turn signal switch in right or neutral position	Measure the voltage between terminals E6 and C3:There should be battery voltage.	Faulty turn signal switch A short to ground in the wire
E5*C3	RED*BLK	Turn signal switch in right position	Measure the voltage between terminals E5 and C3:There should be less than 0.2 V.	Faulty turn signal switch An open or high resistance in the ground wire
E5*C3	RED*BLK	Turn signal switch in left or neutral position	Measure the voltage between terminals E5 and C3:There should be battery voltage.	Faulty turn signal switch A short to ground in the wire

5. Turn the vehicle to the OFF (LOCK) mode.Disconnect the connectors to the body control module, and do the following input tests:

If any test indicates a problem, find and correct the cause, then recheck the system.
If all the input tests prove OK, replace the body control module .

Cavity	Wire	Test condition	Test: Desired result	Possible cause if desired result is not obtained
B17	LT BLU	Under all conditions	Connect terminal B17 and A1 with a jumper wire:The left rear turn signal light should come on.	Faulty LED Poor ground (G505) or an open in the ground wire An open or high resistance in the wire
B18	BLU	Under all conditions	Connect terminal B17 and A1 with a jumper wire:The left front turn signal light and left side turn signal light* should come on.	Faulty LED Poor ground (G351, G401*) or an open in the ground wire An open or high resistance in the wire
B34	LT GRN	Under all conditions	Connect terminal B17 and A1 with a jumper wire:The right rear turn signal light should come on.	Faulty LED Poor ground (G504) or an open in the ground wire An open or high resistance in the wire
B35	BRN	Under all conditions	Connect terminal B17 and A1 with a jumper wire:The right front turn signal light and right side turn signal light* should come on.	Faulty LED Poor ground (G251, G402*) or an open in the ground wire An open or high resistance in the wire

*: With side turn signal light
