Gauge Control Module Input Test

NOTE:

Make sure the fuses associated with the system are OK.
If you are troubleshooting multiple DTCs, be sure to follow the instructions in B-CAN System Diagnosis Test Mode A .
Before testing, do the gauge control module self-diagnostic function , and make sure the B-CAN communication lines are OK.

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

2. Disconnect the gauge control module connector A (32P).

3. Inspect the connector 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.

4. Reconnect the connector, 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 gauge control module .

Cavity	Wire	Test condition	Test: Desired result	Possible cause if desired result is not obtained
A1	WHT	Under all conditions	Measure the voltage to ground:There should be battery voltage.	An open or high resistance in the wire

*1: With auto idle stop system

*2: Without auto idle stop system

*3: With washer fluid level switch

Cavity	Wire	Test condition	Test: Desired result	Possible cause if desired result is not obtained
A17	LT BLU* 1BRN* 2	Vehicle ON mode	Measure the voltage to ground:There should be battery voltage.	An open or high resistance in the wire
A4	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
A32	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
A11	GRN	Vehicle ON mode, brake fluid is at full level in the reservoir	Measure the voltage to ground:There should be battery voltage.	Faulty brake fluid level switch A short to ground in the wire
A11	GRN	Vehicle ON mode, brake fluid is at lower level in the reservoir	Measure the voltage to ground:There should be less than 0.2 V.	Faulty brake fluid level switch Poor ground (G251) or an open in the ground wire An open or high resistance in the wire
A8	GRN	Vehicle ON mode, ECON switch pressed	Measure the voltage to ground:There should be less than 0.2 V.	Faulty ECON switch Poor ground (G402) or an open in the ground wire An open or high resistance in the wire
A8	GRN	Vehicle ON mode, ECON switch released	Measure the voltage to ground:There should be battery voltage.	Faulty ECON switch A short to ground in the wire
A24* 3	PUR	Vehicle ON mode, washer fluid is half or more in the washer reservoir	Measure the voltage to ground:There should be battery voltage.	Faulty washer fluid level switch A short to ground in the wire
A24* 3	PUR	Vehicle ON mode, washer fluid is empty in the washer reservoir	Measure the voltage to ground:There should be less than 0.2 V.	Faulty washer fluid level switch Poor ground (G251) or an open in the ground wire An open or high resistance in the wire
