2. Remove the battery from the vehicle.
3. Inspect battery carrier for damage caused by loss of acid from the battery. If
acid damage is present, it is necessary to clean area with a solution of clean
warm water and baking soda. Scrub area with a stiff bristle brush. Wipe clean
with a cloth moistened with ammonia or baking soda in water.
4. Clean the battery, especially the top with same solutions as described in step 3.
5. Inspect the battery case and cover for cracks. If cracks are present, battery must
be replaced.
6. Clean the battery post with a suitable battery post cleaning tool.
7. Clean the inside surfaces of the terminal clamps with a suitable battery
terminal cleaning tool. Replace damaged or frayed cables and broken terminal
clamps.
8. Install the battery in the vehicle.
9. Connect the positive and negative cables to the battery in the order of mention.
10. Tighten the clamp nut securely. BATTERY CHARGING Battery electrolyte temperature may temporarily be allowed to rise to 55°C (131°F).
Increase of electrolyte temperature above 55°C (131°F) is harmful to the battery,
causing deformation of battery cell, decrease in life of battery, etc.
case is cracked or leaking to protect hands from
the electrolyte. A suitable pair of rubber gloves
(not the household type) should be worn when
removing battery by hand.
WARNING:When batteries are being charged, an explosive gas
forms beneath the cover of each cell. Do not smoke
near batteries on charge or which have recently
been charged. Do not break live circuits at the
terminals of the batteries on charge. A spark will
occur where the live circuit is broken. Keep all open
flames away from the battery.

CIRCUIT OPERATION
Battery positive voltage is supplied to the stoplight switch (terminal 2 and 3). When the brake pedal is depressed, battery positive voltage is applied to the
PCM (terminal 9 and 33).
DTC SET CONDITIONS
CHECK CONDITION
The "CRUISE" indicator light illuminates.
Judgement Criteria Short in stop light switch circuit. Open circuit in the brake switch circuit (between PCM terminal 33 and
ground).
TROUBLESHOOTING HINTS (The most likely causes for this case:)
Malfunction of the stoplight switch. Damaged harness or connector. Malfunction of the PCM.
DIAGNOSIS REQUIRED SPECIAL TOOLS:
MB991223: Harness Set MB991923: Power Plant ECU Check Harness MB991958: Scan Tool (MUT-III sub assembly)
MB991824: V.C.I. MB991827: USB Cable MB991910: Main Harness A

3. Turn the ignition switch to the "ON" position.
4. Measure the terminal voltage between special tool 18-pin connector
terminal 9 (PCM connector B-18 terminal 9) and ground.
When the brake pedal is depressed, the voltage should measure
battery positive voltage (approximately 12 volts). When the brake pedal is released, the voltage should measure 1 volt
or less.

5. Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the measured voltage battery positive voltage (approximately 12
volts) when the brake pedal is depressed and 1 volt or less when the brake
pedal is released?
YES : Go to Step 21 .
NO : Go to Step 5.
STEP 5. Check PCM connector B-18 and joint connector (1) C-04 for
loose, corroded or damaged terminals, or terminals pushed back in the
connector.

2. Measure the power supply voltage between stoplight switch connector C-
03 terminal 2 and ground by backprobing.
When the brake pedal is depressed, the voltage should measure 1 volt
or less. When the brake pedal is released, the voltage should measure battery
positive voltage (approximately 12 volts).

Q: Is the measured volta
ge 1 volt or less when the brake
pedal is de
pressed
and battery positive voltage (approximately 12 volts) when the brake
pedal is released?
YES : Go to Step 9.
NO : Go to Step 12 .
STEP 9. Check stoplight switch connector C-03 and joint connector (1) C-
04 for loose, corroded or damaged terminals, or terminals pushed back in
the connector.

3. Turn the ignition switch to the "ON" position.
4. Measure the terminal voltage between special tool 23-pin connector
(without red tape) terminal 33 (PCM connector B-19 terminal 33) and
ground.
When the brake pedal is depressed, the voltage should measure
battery positive voltage (approximately 12 volts). When the brake pedal is released, the voltage should measure 1 volt
or less.
